User interface

Each module has a similar user interface and consists of the following parts:

Menu bar | Tab menus | Toolbars | Application window | Quick tools | Status bar | Tool palette | Dialog

Window-001c.gif
 

Menu Bar

The Menu bar contains file operations (File), editing commands (Edit), drawing (Draw), assistant tools (Tools), settings (Settings), views (View), window-system (Window) and user-guides, license info and about (Help).

Menu commands having icons next to their names can be organized in Toolbars around the Application window. Some commands can be executed by hotkey displayed behind the command name.

Tab menus

Tab menus contain the main functionalities and their order displays the recommended structural design workflow.

Performance based designOnly available for Turkish seismic analysis

By default, Tab menus have different Object layer settings to protect their elements from the others. That means, for example, structural elements (defined at Structure tab) are protected against load editing (Load tab) although they can selected for load definition. Of course, the available layers of tabs can be customized (Status bar > Current layer). The optional module Documentation can be launched from the Tab menus bar

Toolbars

The Menu bar commands can be grouped in toolbars with their icons and placed next to Application window.

By default, all five toolbars are displayed. If you right-click anywhere on the menu or on one of the displayed toolbars, a list appears, where toolbars can be set visible or hidden.

customize toolbar 001.png

Customize… allows you to edit the command content of the toolbar, on which the right-click is used. A toolbar can be moved into new position by dragging it with its “Top/Left thick horizontal/vertical line”.

Application window

Two main windows types are available in FEM-Design:

  • Graphical window
    It works as a drawing board and displays the model defined in the current project.
  • Detailed result window
    Analysis and design results with detailed background calculation formulas (code references), figures and tables can be displayed by single elements or by design groups in separate windows. Quick navigation is powered with zooming details.

An arbitrary number of windows can be opened (Window menu) to show for example a model in different views at the same time. The list of the currently available windows is shown at the bottom of the windows (tabs) and in the Window menu. You can swap between the windows by clicking on their name tabs or by choosing the requested one in the Window menu. Applied windows can be arranged by Window > Arrange. Right-clicking on a window tab, the window’s name can be edited.

application window_FD19.00.001.png

Quick tools

Quick tools is a tool window that contains the often used functions such Layers, Results and Filter.

Quick tools 001.png

Quick tools can be enabled in several ways:

  1. Settings > Environment > General > Quick tools
  2. Right click on the toolbars > Quick tools
  3. Window tab > Other windows > Quick tools

Quick tool window can be placed anywhere on the screen and it can be docked to the left and right side of the FEM-Design model view area. The docked Quick tool window can be also collapsed.

Quick tools 002.png

Status bar

The Status bar is situated under the Application window and separated into the following parts.

status bar_FD19.00.001.png

  • Command
    Field to enter coordinates and shortcut commands. Command line also displays additional messages to show the steps of the current command.
  • Selection
    Number of the selected elements (bars, shells, supports, loads, etc.) can be seen in the lower part of design area.
  • Co-ordinate box
    It shows the exact coordinates of the crosshair cursor in the current co-ordinate system. Coordinates can be also given for point/direction definition in a dialog appears after clicking on the Co-ordinate box (see Entering Co-ordinates).
  • Layer button
    Clicking the button opens the Quick tools-tab. All layer operations like defining new, renaming, color-assignment, showing/hiding and deleting are available in the layer-system dialog.
  • Point/Direction editor
    Editor tools provide reference points and lines by using existing lines and points during element definition, drawing and editing.
  • Object snap tools
    Here you can set the snapping distance and turn object snaps on and off.

Tool palette

In most cases, a command/tool has own palette (Tool palette) that contains its definition and setting tools.

toolbar 001.png

Figure: An example for tool palette (Beam command in 3D Structure module)

The parts of a tool palette are:

  • Toolbar - It gives the editing modes and their additional tools. The main editing modes are:
    • Define: creates new objects according to its current settings (“Default settings”).
    • Properties: asks and/or changes the properties of selected object(s).
  • Default settings - If this button has 3D shape, then you can set all default parameters for the new object. Otherwise, it only shows the symbol of the function.
  • Main settings - The frequently changed parameters of the new object (Define) can be set directly in tool palette.

You can usually use a dialog to modify the settings, the properties of a command; it contains text and number fields where you can set parameter values.
The main difference between dialogs and Tool palettes is that you can work beside an opened tool palette, but cannot at a dialog.
There are three main switch types at a dialog or a tool palette: check boxes, radio and chain buttons.

Chain button 001.png

Figure: Function of chain buttons

In case chain button exists and it is “Active” (pushed in), any changes made to the related edit box will be transferred to the next edit box automatically. It gives a quick definition of defining surface elements with constant thickness, loads with constant intensities etc.

Dialog

The Default settings dialog is used to change the properties of new objects. It usually contains a General tab where many commands and identifiers are shown, some dialogs also contains tabs for cross sections, materials and boundary conditions/connections.

dialog 001.png

Program Settings

Clicking Settings > All opens a dialog with all available settings of the program and the current project.

1584526396270-287.png

Figure: Project and program settings

The settings are valid for the current project, but they can be extended for later projects by saving them as default settings. OK closes the dialog and validates the settings for the current project. Save as default set the “selected” project settings available for next projects and new files.

warning.png

“Selected” means that Save as default works only for the branch belongs to the list/folder title selected by the cursor. For example, apply Save as default for “Environment” to save the General, the Directories and the Cursor settings as default, or select “Settings” and click Save as default to store all current settings as default values.

The range of available settings depends on the currently opened Tabmenu. For example, all setting are available at launched “Structure” tabmenu, but the settings are reduced with e.g. finite element (Mesh) settings in case of activated “Analysis” tabmenu.

The program stores project and default settings in the fem.ini file can be found in the “FEMData” folder of the installed program.

New program release can use the default settings of the previous release, if you keep them after the first running of the new release in a warning message dialog.

Environment

General settings enable the user to adjust the main program settings affect on startup, system, rendering and display style.

  • Check for update at start
    By default, the program informs the user if a new official release of the current FEM-Design version is available.
     
  • Check for upgrade at start
    It sends a message if a newer commercial FEM-Design version is released. In this case, the newer version can be downloaded, but it can be run only in demo mode till renewing the current license agreement (please contact your local distributor).
     
  • Auto load last drawing
    Checking this box opens the last project at program start-up.
     
  • Language
    By default, the user interface is displayed in the installation language. Ask your local distributor about the available languages in your country.
     
  • Timesave [min]
    It defines the time period in minute for automatic project saving. Read more at Data safety.
     
  • Undo steps
    The number of executable undo steps can be set in the field. But do not forget, that there are some complex calculation processes (analysis, mesh preparing etc.) Undo does not work on.
     
  • Graphic engine
    The suitable graphic engine can be set here by choosing “DirectX” or “OpenGL” according to the video card.
    The DirectX graphic engine is faster than OpenGL on most of the computers. We recommend the User to check which graphic engine performs better on his computer.1584526922243-872.png
    light.png

    For more information about the graphic engine read the Remarks.

    warning.png

    If you have any rendering problem with the default graphic engine, apply the other one. In case of further troubles, download the latest driver of your graphic card.

    Safe mode” is developed to protect the program from possible video drive crashes. If no graphic problem is detected with the current driver, uncheck this box to take the full advantage of the new powerful graphic engine and to reach the maximum rendering speed.

  • Enable Win8/Win7/Vista style
    By default, the user interface is developed in the height of Microsoft Windows 8, 7 and Vista fashion. Unchecking the box a simpler interface will be available after restarting the program.
     
  • Window background
    The color of the drawing background (graphical windows) can be set here. The default and suggested color is white. Objects having the same color with the background are always displayed in inverse color.
     
  • Display information pop-up
    If there is no running command, moving the cursor over an element displays an Information pop-up with the element’s main properties. Depending on the currently used working mode (Structure, Loads etc.), pop-up is available for different elements (structural elements, loads etc.) only. For example, the pop-up displays the ID, the material, the thickness, the alignment and orthotropic features for Plates in Structure mode.
    1584527171977-275.png
    Figure: Information pop-up examples

Directories settings allow the user to specify the location of FEM-Design files.

  • Temporary
    The program stores temporary files during calculations and mesh generations in the given folder, which will be automatically removed, if the operations are done successfully. Remained temporary files can be erased from the Temporary folder after closing the currently opened project. The changes made in Temporary directory will affect after the program is restarted.
     
  • Working
    The default favorite folder can be set here for the open and save commands.

The style of cross-hair cursor can be set in Cursor dialog. It can be full-sized in graphical windows or custom-sized (Limited) by the scroll tool.

Drawing

Title dialog allows the user to specify the content of drawing title block (Draw > Title information table) and the header title of printing (File > Print). Project, Description, Designer, Signature and Comments attributes are autotexts. That means, modifying their content updates all titles used in the current project. These five title attributes can be used in documentation and reinforcement list templates with the help of Field tool (Draw menu).

1584527715406-518.png 1584527732558-607.png

Figure: Title information table

Scale has effect in displaying texts, line types and wall hatches in graphic windows. Of course, printing scale can be set independently from drawing scale.

Param settings allow the user to specify the default initial settings for drawing (Draw menu commands) in the current or later projects (Save as default). Line type, pen width and drawing color can be edited independently from the default values with the Status bar tools “Current style”, “Current layer” and “Current color”.

Text settings enable the user to set the default font style and sizes for general text items.

Table: List of elements on which Text setting has effect or not

Dimension, Axis and Storey tools and the finite element display have individual text settings from the general Text settings.

light.png

Script solves the character problems of different languages. For example character “ő” appears as “õ” in “Western”, but as correct “ő” in “Central European” script.

Size is defined in real values (mm), so text size varies on drawings by modifying its Scale.

The Width factor 1.0 refers to the normal character width, so factor smaller/greater than 1.0 results a condensed/extended text.

For “italic” style use Slant between 10 or 15 degrees.

Calculation

Calculation includes settings influence structural behavior, finite element mesh generation, analysis and result.

Code displays the current and available design code for the current project. Code influences:

  • the range of available modeling materials,
  • automatic combination of load groups, and
  • the method and result of reinforcement, steel and timber design.

Changing the current code erases the materials, the design parameters and the results in the project, so these properties have to be redefined to run valid calculations later.

Read more details from other Calculation settings in the connected topics:

  • “Rigid” values
    The default value of “infinite rigidity” can be set for supports, connections and fictitious bars by types.
  • Mesh
    Mesh and peak smoothing settings of automatic finite element mesh generation.
    Perform gives additional features to data safety.
  • Analysis
    In Analysis you can decide the way of Automatic save, in Find identical copies before calculation for you can set if the program should check the identical copies of structural elements and/or loads and in Warnings it can be checked if the program should warn about using non-linear elements in a linear calculation.
  • Result
    Options define the calculation sections of bars and affect on detailed results of bars.

Display

The current and default display settings of the drawing elements, numbers, structural objects, loads and finite elements/mesh can be set here.

Displaying structural and analytical element ID’s is separated in order to avoid duplicate labels on the screen. The required ID can be set by Bar and Shell elements in Display settings dialog.

1584527995499-252.png

Figure: Display settings (Bar, Shell)

Window

Co-ordinate systems include the display settings of the Global and the User-defined (UCS) co-ordinate system symbols. The symbols are shown in the defined size in working windows, but they can be hidden by unchecking the Display co-ordinate systems box.

Grid defines the distribution settings of the visible Construction grid. The grid can be hidden by unchecking the Display grid box. The grid lines can be set to be parallel with the axis directions of the Global (Ground) or UCS system.

All default settings of Object Snap tools are grouped in Snap dialog.

In different windows different scales can be defined, which is especially useful in documentation module. By choosing an appropriate scale factor the displayed labels are easy to read. In another window the parameters can be decreased to highlight another result.

Units setting offers various unit types for modeling (length, angle, force, mass and cross-sectional data) and for results. Stress and displacement units can be set independently of the length and force units.

Data Safety

Time saving and protection system ensures more the data safety of working files.

Time Save

FEM-Design automatically saves copy of the working file by given time period.

The saving time period can be set in minutes at Settings > All > Environment > General > System > Timesave.

1584528146302-798.png

Working on a project file called e.g. “steel construction.str” in the 1584528158180-507.png  3D Structure module with a 15-minute time save period, an extra file will be generated and updated by the time period (0, 15, 30min …) with special extension and in a hidden folder:

Rules of time save:

  • In case of a program crash, the last saved copy opens automatically in the right module.
  • If you successfully exit from FEM-Design after saving the current project, its time save copy will be erased from the recovery folder.
  • The location of time save files cannot be modified for data safety.
warning.png

Additional automatic savings can be set before and after calculations at Settings > Calculation > Analysis > Automatic save…, but automatic savings overwrite the original project file.

Recovery files

Recovery file command in File menu is for managing time-save files which are generated after some unexpected events. Its tool-window:

1584528246118-584.png

Figure: Recovery file dialog

You can open the desired version and delete the useless ones, and you can also set the sorting criterion, by clicking on File / Date / Size.

Protected Work File

All working files are locked not to be modified, overwritten by another user or process. Starting a project, a file having the project name with .lck extension is generated automatically, which guarantees the protection till closing the working file.

Opening a protected file sends the warning message: “The file is locked by another user or process.” You are allowed to open and modify the content of a protected file, but changes can be saved only under a new name (File > Save as).

Element Types

Two main types of elements are available in FEM-Design: Drawing elements and (structural) Objects. These element types are stored in different Layer-systems and have different kind of property and display settings.

Layers

The FEM-Design layer-system helps you to work in a well-organized way in drawings and in models while constructing and documenting. The layers can be considered as transparent papers put on top of each other will seem to be one drawing. All layers can be reached in a dialog appears by pressing the Current layer button.

Layer Types

Regarding the element types there are two main layer types: “Drawing” and “Objects”.

1584538310191-735.png

Figure: “Drawing” and “Objects” layers

Drawing” layer contains all drawing elements defined by the Draw menu commands or generated from DWG and DXF imports. Drawing layers can be renamed and erased, and their colors and states can be edited. Only the default “0” layer cannot be deleted and edited. At the same time only one drawing layer called “Current” can be used for drawing. The name of the “Current” layer is appears on the Current layer button. The “DIM” layer is a special drawing layer for the dimensions. It is automatically created by using the Dimension command (Draw menu). ”Drawing” Layers can be excluded from the Object Snap by dechecking the „No snap” option in the Sn column.

1584538330044-725.png

Figure: „No snap” option

Objects” layers are built-in layers for objects like plate, wall, column, supports, loads etc. Each object type has an own layer (e.g. walls are displayed on the “Wall” object layer). Objects layers are not allowed to be deleted and renamed, but their states and the display colors and pen width of objects can be edited. ”Objects” Layers can also be excluded from the Object Snap by checking the „No snap” option.

Point Definition with Co-ordinates

Points can be defined with their co-ordinates in Descartes or Cylindrical co-ordinate systems.

1584538716679-278.png

Figure: Co-ordinate system types for point definition

Point co-ordinates can be defined in various unit types available at Settings > Units (Length and Angle).

The crosshair cursor position can be displayed on the Status bar in the Descartes or in the Cylindrical co-ordinate system by clicking the 1584538745675-880.png  symbol of the Co-ordinate box.

Descartes Orthogonal Co-ordinate System

(Cartesian co-ordinate system)

The individual co-ordinates represent the distance of the point from the origin of the orthogonal co-ordinate system (absolute) or from a previously defined point (relative) measured along X, Y and Z axes. Cartesian co-ordinate system is available for co-ordinate definition both in the Global co-ordinate and the UCS systems.

Cylindrical Co-ordinate System

(Polar co-ordinate system)

Point is defined by three components: an angle (a1) and two distances (d1 and d2). The a1 and d1 co-ordinates define the point position in the XY plane of the Global co-ordinate and the UCS systems, d2 sets the distance from the XY plane. The angle and the distances can be given from the origin of the co-ordinate systems (absolute) or from a previously defined point (relative).

Co-ordinate Definition Modes

Point co-ordinates can be defined by typing them in the Command line or the Co-ordinate box of the Status Bar, or just by mouse-clicking combined with the Object snap tools in the drawing area or in special points.

Absolute co-ordinate definition

Co-ordinates of a point are defined as distances/positions from a co-ordinate system origin.

Table: Absolute co-ordinate definition modes

Rules of co-ordinate definition:

  • Co-ordinates given in Command line are valid only in UCS. But, if the UCS and Global system are in the same position (same origin and same axis directions), the defined point will be in the similar position in both two systems.
  • Decimal point has to be defined as “. ” and not “,”.
  • If you do not give Z value in the 3D modules, its value will be automatically zero.

Relative co-ordinate definition

There are three ways to define a point with given distance from another point (called “relative co-ordinates”).

Relative coordinates can be defined both in the Descartes and the Cylindrical co-ordinate systems and both in the Global and the UCS systems.

Relative (A): Distance from the last defined point

Distance from the last point can be defined in the Command line or with the Co-ordinate box. This mode is useful while creating line/polyline/polygon/surface with the distance from the start/previous point.

Relative (B): Distance from a selected point

With the help of function key 1584539434842-740.png  and the Co-ordinate dialog box, a point can be defined from the point on which the cross-hair cursor is left. The steps of definition:

  1. Leave the cursor above the required point found by one of the Object snap tools, which you would like to define the distance from.
  2. Click 1584539435991-327.png  function key.
  3. Set the distance co-ordinates in the Co-ordinate dialog according to a selected co-ordinate system.

Working Plane

The default working plane – where the points and coordinates are defined – is the following by different FEM-Design modules.

warning.pngIt is very important to set correct position (plane) for the structural model. For example, although the default working plane is the Global XY plane in the 3D design modules, place the model of a 2D frame in a vertical (Global Z) plane with the help of a vertical working plane, because the gravity direction is always the Global Z axis direction.

1584539816294-746.png

The program automatically sets the working plane into the reference plane of a planar element (plate, wall, surface support, surface load etc.), if you use the Hole tool to cut hole in a structural element or a load.

Grid Systems

The program offers a number of aid tools finding specific points and directions while drawing and editing. These are the Grid system and the Object snap tools.

Two grid systems are available in the program: Construction grid and Snap grid.

Construction grid

By default, Construction grid is the grid visible in the working plane. Of course, it can be hidden at the program settings (Settings > All > Window > Grid). That grid sets the characteristic sizes of your project.

1584538159454-437.png

Figure: Construction grid and its settings

You can snap to the raster points of the Construction grid permanently by activating the 1584538172177-485.png  “Raster” Object snap tool and temporarily by holding down 1584538179396-485.png  function key. By default, the grid directions are parallel with the UCS axis directions, so you can rotate the grid together with the UCS.

Snap grid

Although Snap grid is an invisible grid, you can join to its raster points permanently (Raster tool) or temporarily 1584538182403-581.png  as written before at Construction grid. The distribution of the grid can be set at Object snap tools or at Settings > All > Window > Snap. The grid distribution can be set as default for the project/program in the latter setting dialog.

1584538202100-801.png

Figure: Snap grid and its settings

The X and Y directions are always parallel with the UCS axes.

Settings affect the Snap grid (Raster dialog box):

  • Dot cursor
    If it is active, a small black dot shows the grid points at applied Raster snap.
     
  • Sensitivity
    It sets the sensitivity area of the raster snap for both the grids and other snapping tools. The sensitivity is constant while zooming.

Object Snap Tools

The Object snap tools finds and joins to special points of drawing elements and objects. The cursor form changes to the symbol of the actually used Object snap tool. A snap tool can be activated permanently by clicking its icon on the Status bar or checking its box in the Raster dialog box. The dialog shows the hotkeys of the snap tools activate the current tool temporarily while holding down the key.

Settings affect to the Object snap tools (Raster dialog box):

  • Dot cursor
    If it is active, a small black dot shows the points found by the applied Raster tool.
     
  • Symbol cursor
    If it is active, the symbol of the current Object snap tool when the cursor finds the similar snap point.
     
  • Sensitivity
    It sets the sensitivity area of the raster snap for both the grids and other snapping tools. The sensitivity is constant while zooming. Too high Sensitivity value makes more difficult to find a point from the neighbors close to it.
light.pngSnap will not work on objects obscured by other elements (such as surfaces) outside of Wireframe.

User can exclude entire Drawing layers from the snapping on its objects. For more information see „No snap” option.

Selections

Mouse and keyboard selection

FEM-Design offers various selection modes to select objects for requiring and modifying their properties and for editing. If selection is possible, the available selection modes appear in the Command line.

1584540453885-722.png

Figure: Selection modes displayed in the Command line

light.pngUse 1584540503252-693.png  to restart selection, if you make mistakes while selecting.

Box selection

Rectangular selection box can be defined with two points placed with the 1584540512028-683.png  mouse button. Depending on the box definition, the box selects elements:

  • that are fully in the defined rectangular area                       →     the end corner of the box is on the right from the start one,
  • that are fully or partly (intersected) in the defined area       →     the end corner of the box is on the left from the start one.

1584540526312-870.png

Figure: Box selection modes

Object selection

Use 1584540537074-157.png  on an object to select it directly. If you click on a common part of more objects, the first drawn one will be selected.

Holding 1584540558567-862.png  pressed and by using 1584540564551-407.png  objects can be added to or subtract from the current selection.

Selection of same type elements

It is a quick selection to select visible elements defined with the same command (e.g. selection of all walls created by the Wall command). Just hold down 1584540570950-302.png  and select on element (e.g. one wall element) with 1584540539457-811.png , and all same type elements will be selected (e.g. all walls) independently their properties differ or not.

Select all

Depending on the current command, all visible elements (e.g. for the Edit > Move command) or all visible same type elements (e.g. for the Properties tool) will be selected by using 1584540593271-434.png  and 1584540601842-916.png  together.

Multiple-selection

  • ‘+’ sign is drawn if multiply selection is active (by pressing 1584540591106-171.png )
    1584540614110-832.png
  • The selection box has different colours depending on the way of the selection:
    1. By ‘left-to-right’ selection (the included objects get selected) the colour of the selection box is blue.
      1584540634349-461.png
       
    2. By ‘right-to-left’ selection (all intersected objects get selected) the colour of the selection box is green.
      1584540674388-107.png
       
    3. By area selection (e.g. to print the selected area) the colour of the selection box is grey.
      1584540696608-820.png
       

Multiple selection can be ended by 1584540709849-138.png  + 1584540542433-847.png  (it has the same effect like pressing 1584540722536-649.png ).

  • For pressing 1584540712365-549.png  + 1584540544465-727.png  in the application window (without any active tool palette) the quick menu appears.
  • When a tool palette (e.g. Beam tool palette or Point load tool palette) is active, for pressing 1584540715819-107.png  + 1584540546512-678.png  the properties of the items belonging to the active window appear.

Filter selection

Filter is a pop-up window in the workspace, which helps to select the requested objects easily for all kind of editing and modifying functions. When clicking on it, the following appears:

1584540735817-825.png

With the cursor pointing on Point support group +, -“ and ”&” buttons appear, enabling the user to add or remove point support group elements. If you want to select most, but not all of the point support groups, you should click +, and then “Continue” for deselecting the few individual supports not needed for the selection.

The ”&” button works as an “AND” boolean operator: If you want to select the columns on the second storey, you have to click +” at column and then ”&” at storey 2.

After closing the Filter palette, it can be switched on again by a right click on any toolbar, or on the main menu zone. Another way is available through Settings>All…>Environment>General>View, where filter palette can switched on and off:

1584540811194-956.png

User defined filter 1584540834379-665.png  in Tools menu is a function for saving some frequently used selections. If you define a filter of your own, it will appear at the bottom of the list. When defining, a name has to be given and then desired objects have to be selected. A window appears “Filter has been created.”After this, if needed, with properties ”?”, the name of the block can be modified; with “+” you can add other members, and with “-“, you can remove undesired ones.

It also can be exploded with 1584541535319-672.png :

1584541545545-912.png

At first (like in the figure above) “OK” is grey, but after clicking on Explode button “OK” becomes active. Don’t forget to validate the explosion with “OK”, before closing this window.

Thanks to the improved video engine, the advantage of all modern displaying technologies such as live pan, live rotation, live zoom, special display modes and transparency (see the next chapter) is available in FEM-Design.

light.pngThe suitable graphic engine can be set at Settings > All > Environment > General > Graphic engine.

Pan

Panning view on the drawing area can be done in different ways. “Panning” modifies the current view only and not the position of elements.

1584541879497-911.pngFirst start Animate pan from the View menu or View toolbar, then press 1584541912084-338.png or 1584541940233-167.png and drag the mouse to pan the current view. If you are in panning mode, you cannot edit the model and the currently running command is also paused. Click 1584541953389-453.png  to exit panning mode and return to editing mode.

However, while in editing mode, you can temporarily simulate Animate pan by pressing the 1584541962993-884.png to pan the view. Release the mouse button to stop panning.

With the command Pan (View menu) the current view can be moved with a displacement vector defined by two points.

Orbit

View rotation can be done in different ways. “Orbit” modifies the current view only and not the position of elements.

1584542063828-524.pngFirst start Orbit 1584542090957-850.png  from the View menu or View toolbar, then press 1584542096375-762.png or 1584541930926-995.png and drag the mouse to turn the model around its center point. If you are in rotation mode, you cannot edit the model and the currently running command is also paused. Click 1584542103577-570.png  to exit rotation mode and return to editing mode.

However, while in editing mode, you can temporarily simulate Orbit by pressing 1584542109198-582.png  together with 1584541933761-337.png to orbit the model. Release the keys to stop rotating.

Alternatively, you can press 1584542131701-486.png  together with 1584542137439-171.png  to orbit around the closest valid snapping point to the cursor; in some cases, this may result in a more predictable orbiting behaviour. Valid snapping points include points specified by the Object Snap tool, or outside Wireframe view mode, also the closest surface point to the cursor.

1584542169711-962.png

Rotation view can be set in a dialog box too with the command 3D Rotation (View menu).

Views

Besides of navigation tools, specific built-in 2D and 3D views can be used to set the required project view. All views can be stored with given names (user-defined views).

Built-in views

1584542320420-959.png

Just click one of the following view buttons to set a specific 2D view or a general 3D view:

User defined views and Home view

To return frequently to a view of the current project, you can save it as “Home view” (View > Home view > Save as). Choose View > Home view > Return to set this view just with one-click. Home view is saved with the project.

Current view can be also saved with names in a dialog appeared by clicking 1584542391298-734.png  (View > User defined views) or using 1584542400506-274.png +1584542439686-465.png . Define a name and click Add to store the view. If you have more than one user defined views, Select displays preview of them. To use a stored view as the current one, click Select and exit. The list does not contain the Home view. User defined views can be saved with the 2D and 3D View commands too.

1584542418145-971.png      1584542423218-831.png

Figure: 2D and 3D View commands

Vertical plane

Creates a section/view parallel with the global Z axis by selecting two points.

Horizontal plane

Creates a section/view perpendicular to the global Z axis by selecting two points.

Object plane

The section/view plane is parallel with a selected region (Plate, Wall etc.) plane. The final direction can be set by moving the cursor at the selected storey. The view direction is always the opposite of the local Z’ direction of the selected surface object.

3 points

The section/view plane is defined by adding three points. The first point defines the origin, then the second point defines the X direction together with the first one, and finally the third point defines the Y directional extension of the plane. The last point also defines the view direction (an arrow shows it).

User Co-ordinate System

The section/view plane is set to the X-Y plane of the UCS. The view direction is always the opposite of the Z axis of the UCS.

Dialog

With this tool, you can define the position of the section/view plane in a dialog box. At 3D View, Dialog opens 3D Rotation.

Axis

Axes (Axis objects) have multifunction in FEM-Design. They can be used to find special points and to define different kind of planes:

  • Intersections of axes
    1584534114970-331.png
    Figure: Intersections may define column base points
     
  • Working plane
    1584534155666-909.png
    Figure: Working plane defined on an axis by UCS
     
  • View planes (2D View and 3D View commands)
  • Project planes (used in the model transfer between the FEM-Design modules)
    1584534224633-899.png Wall module can open an axis plane defined in the 1584534243024-768.png  3D Structure model and imports the walls attached to the view.

New axis or axis-system can be defined with the  1584534263441-700.png  Axis command of the 1584534270926-937.png  tabmenu. Both constant and variable distribution of axes can be defined in the Axis tool palette.

Definition steps

  1. Set the required horizontal working plane (UCS), where you would like to place axis/axes.
  2. Use the 1584534286532-863.png  Define tool. Define the distribution in the Multiple axes description field. If distance is not defined, you can place one axis object as a line on the UCS working plane.

    Constant spacing:
    (n-1)xd                                       where n means the numbers of axes, x is the multiplication sign and means the distances between the axes.

    Variable spacing:
    (n1-1)xd1,(n2-1)xd2,...              where ni means the numbers of axes per different spacing, x is the multiplication sign and di means the different distances.

    1586250172471-403.png
    Figure: Axis-system with constant and variable spacing
  3. Label type (Number or Letter), starting character (No/Letter) and Prefix can be defined for the new axis/axis-system in the Axis tool palette.
  4. Display settings of axis symbols, colors and label can be set at 1584537384178-315.png  Default settings.
  5. An axis or the start axis of a system can be easily defined as a line with 2 points in the working plane. The distribution orientation can be changed by clicking 1584534358296-971.png  before the definition of the axis end point. The program places all axes on the Axes object layer.

Optional steps:

  1. The numbering of an axis or one direction of an axis-system can be modified with the 1584534352090-284.png  Renumbering tool. Define new (start) numbering value in No/Letter field, and then select the axis you would like to renumber.
  2. Display settings of the axis symbols can be modified with the 1584534345415-258.png  Properties tool.

Storey

Stories (Story objects) have multifunction in the 1584534307330-961.png  3D Frame and 1584534315446-217.png  3D Structure modules. They can be used to define different kind of planes:

  • Working plane

New storey or storey-system can be defined with the 1584536653224-615.png  Storey command of the 1584536659573-171.png  tabmenu. Both constant and variable distribution of stories can be defined manually in the Storey dialog box.

1584536668129-734.png

Figure: Storey dialog box

Definition steps

  1. Set the Horizontal size of the building. This rectangular size will be the floor plane size of the storey object.
    warning.pngThe horizontal size and the summa height (see later), which define the whole model size, effect the automatic wind load calculation.
  2. Set the height of the Ground level and Bottommost level.
    warning.pngGround level also effect to the automatic wind load calculation, because the load values depend on the distance from the foundation level.

    Bottommost level
    This is the storey’s origin height, so the storeys are starting from this level.
     

  3. To define the first storey, set a name for it in the Storey cell of the first row, and then give the Height of the storey. Then, define further required stories in the same way. You can also edit the level of a storey that automatically updates the story height.
  4. Set the display settings (symbol and label size of the level dimensions) at Properties.
  5. Clicking OK generates and displays the storey-system in the project. The program places all stories on the Stories object layer.

Creating a storey-system automatically generates view planes by stories. Fast navigation among those storeys can be done with the keyboard or by using Select view:

1584536865347-655.png

Figure: Navigation by Storey

In Settings/Display/Storey dialog you can choose from three options for the appearance of the given storey.

1584536902572-360.png

All objects are displayed which are in the plane of the storey or crossing the storey above or below according to the selected setting.

If the Modify structure is enabled the structure follows the storey system modification, otherwise not.

The modifications displayed with three color code, if the Modify structure is active:

  • green: new storey
  • yellow: modified stroey
  • red: deleted storey

When the Apply button is pressed the modifications proceed immediately without closing the dialog. The following pictures shows this feature though a 4-storey building, where the Storey 4 will be deleted, a new storey is added and the Storey 3 height is increased to 4.0 meters.
