Correct model tool

Correct model tool is a revolutionary function to fix the models having geometrical errors, in semi-automatic way, with supervision of the user. This tool helps to fix the following types of errors in the model:

  • object multiplication and overlap
  • geometrically incorrect objects (very small region parts, very small angles, divided region edges, etc.)
  • incorrectly positioned objects

Correct model tool is a semi-automatic system which necessarily needs user-interaction. It draws attention to the possible errors of the model and in most cases also offers solution(s), but you have to decide whether it is really an error or not and if it is, how to fix it.

Pick Correct model from Tools/Correct model or from the toolbar (1585543145115-858.png ).

Select the elements to be checked.

Then in the pop-up dialog, select the task(s) to be run.

1585543188761-387.png

All correction tasks can be selected or cleared in one click. Use the Select all and Clear all buttons for it.

1585543198098-713.png

Press Start to start the correcting process. It runs row by row and the current step turns green. The view is focused on the incorrect object (part).

1585543223602-220.png

The table below contains the meaning of the flashing red object depending on the current correction task:

Correction task (type)What is flashing?
Delete identical copiesobject to be deleted
Fix overlapcurrent object and its modified version are both flashing
Chamfer sharp anglesthe part of the region to be removed
Fix small areas and linesthe part of the line/region to be removed
Merge region linesthe region line to be merged
Fixing geometrically incorrect objectsthe object to be fixed
Fit objects to storeys, axes and reference planesthe suggested new position of the incorrectly placed object
Fit objects to each other

You can choose from the following choices:

  • Ignore: the object is not modified
  • Mark: the object is marked according to the colour and text set in the Marker dialog
  • Fix: the object is deleted/modified according to the program’s suggestion. The number in the table in Fixed cell of the current correction task’s row is increased by one. The fixed object turns into green

Ignore all, Mark all, Fix all acts on all further incorrect objects found by the current correction task (highlighted by green in the table).

After one of the abovementioned button is pressed, the next incorrect object – if exists – gets into focus and highlighted 

Show again focuses on the current objects. It can be useful at a large model.

Break cancels the correction process but the previously performed modifications are kept.

Once the correction process is finished (or cancelled) the modifications can be applied on the model by pressing either Apply or OK. In case of OK the dialog closes. All modifications can be discarded by pressing Reset if they were not yet applied on the model.

Settings commands let the user save/load the selected correction tasks and their tolerances.

Using Auto button and applying its modification on the model is not recommended, because in practice in most cases there is no exact solution:

  • fixing an error may generate or eliminate other problems
  • fixing the same error in different ways may generate/eliminate different problems
  • consequently, the correcting process can be iterative. 

However, Auto is useful to get an estimation of errors and type of them in the model.

See detailed description of each correcction task as follows.

Delete identical copies

If more identical element exist in the same position, it deletes all multiplication, and counts as one correction in the Fixed column on the Correct model dialog.1585543329069-374.png
warning.pngThis is not working for intermediate sections, post-tensioned cables and corbels.

Fix overlaps

It fixes the overlapping regions and lines. The existing objects can be shrunk or erased, but function will not generate new objects (e.g. a region can not fall apart).

Overlapping is allowed for the Loads.

Sharp angles

Sharp corners under 10° will be fixed according to the given tolerance. The highlighted part of object will be removed. If the element has smaller dimension than the given tolerance, the whole element will be removed.1585543454555-804.png

Fix small areas and lines

Objects within the tolerance range will be removed. It will fix small holes, long narrow areas etc.1585543522189-257.png

Merge region lines

Merge region lines function merges two lines/curves of a region into one line/curve if they are in the range of tolerance. Too flat curves may be replaced by line. The figure below shows examples how the tolerance is measured.1585543575339-823.png

1585543594834-871.png

Align to structural grid

This function aligns objects to the structural grids (axesstoreys or reference planes). Alignment is done by orthogonal projection of object’s checkpoints to the structural grid within the tolerance. The check-points are shown below for line, arc and circle:

1585543612436-600.png

warning.pngOnce an object is placed on a grid by Correct model tool, it will not be detached from it by any next correction step.
warning.pngCorrect model tool does not check structural grid for possible errors, like axes too close to each other or not perfectly parallel.

Stretch to structural grid

This function will stretch the regions and lines to the intersection of axis within given tolerance.1585543658719-705.png
warning.pngIf the geometry of the object is incorrect (e.g. shell is not laying in plane) this function cannot be performed.

Align regions

It aligns the regions (projection) to an other region’s plane which is within the given tolerance both in direction perpendicular to and parallel with  the region’s plane.1585543698519-884.png

1585543714537-539.png

Stretch to crossing regions

This function will stretch the objects to the crossing regions within given tolerance.1585543746459-631.png

Stretch regions in plane

Regions laying in same plane will be stretched to each other within given tolerance.1585543768491-979.png
Lines laying within given tolerance to other objects will be stretched.1585543853367-668.png

Align points

Points (objects) will be aligned to closest object within tolerance.1585543878561-290.png

Example

The following example shows the process of fixing geometrical errors of a small model with different types of errors:

1585543943304-748.png

Query

Starting  1585543958173-382.png  in Tools menu helps to get geometrical informations in the model.  You can get the point coordinates, length between two point, angle, region and solid parameters.

Point coordinates

Choosing a point with 1585543969229-409.png   shows the point coordinates in orthogonal and cylindrical Global co-ordinate system.

1585543974911-811.png

Figure: Point coordinate

Length

Choosing two points with 1585543983242-613.png  shows distance between the selected points and their projection to the  co-ordinate axes.

Angle

Choosing two lines with 1585543987665-664.png  shows the angle between the lines.

Region

Choosing or drawing a region with 1585543992499-220.png  shows area, perimeter, center of gravity (co-ordinates).

Solid

Choosing a solid with 1585543996601-369.png  shows volume, perimeter, area and center of gravity (co-ordinates).

Scripting

We support a basic automation workflow through scripting. It is capable to load/save file, execute analysis calculation and crate outputs as .csv list or .docx documentation.  With that you can batch-analize models created in other programs or directly in .struxml. Or execute long calculations during the night.

The script commands approximate the usual interface, as if you filled inputs on the dialog and press the OK button. So for the meaning of the parameters look at the corresponding panel in the UI.

To launch the script use the menu command Tools/Run script or start the program with the /s command line:

   fd3dstruct /s c:\mydir\example.fdcsript

The installation creates the fdscript.xsd and an example.fdcsript in the templates folder, the latter can be used as a starting point of custom scripts. It has all the commands intended for users and useful comments on how to proceed.

Script execution writes a log file (specified within the script header), you have to look into that to see what was actually executed and any warning/error message that would normally appear on the screen. The execution stops at first serious error.

If you launch FEM-Design many times to execute script for many inputs it's a good idea to turn off all the satellite executables it may launch: update and upgrade in settings and set environment FD_NOLOGO=1 to avoid the splash screen.

We also allow users to use the API.

Block

Blocks can contain only drawing elements (point, line, arc, circle, region, solid and text) for editing these elements in one step.

1585544039366-834.png
Figure: Block toolwindow

Similarly to filter, for definition, you have to type the name first, then select the desired objects. If required, members can be added with the “+”, and removed with the “-“ buttons, and exploded with the explosion symbol at the right hand side. With properties “?”, you can also change the name of the block.

For grouping structural elements or loads User defined filter function can be used.

Archive

This command deletes the result files for save free space in the hard drive. To see the result, you have to run calculation again.

External reference

With this command User can display a drawing of dwg or dxf format as an image in the background. The main advantage of external reference is that  modifcations made in the source file will be executed in the FEM-Design file each time it is reopened, or Refresh function called.

1585544149721-187.png
Figure: External reference toolwindow

After Clicking on Define you can specify the insertion coordinate system:

1585544154970-350.png
Figure: Insertion coordinate system of DWG/DXF drawing

With the third click, you specify the coordinate system’s second axis. The second axis can define reverse polarity compared to the polarity of the referenced image and thus you can get a reverse image (with wrongly directed texts, etc.).

light.png

If the origin in the dxf or dwg file is far away from the drawing, you may not find the image in FD’s workspace. Click on „Zoom margin” in this case:

1585544195978-738.png

Figure: Inserted DWG drawing

In the import window, you can set the conversion scale, select the desired layers, with different colour representations:

1585544231045-625.png
Figure: Import dialog

With the display option in the red box, you can turn the picture on and off.

1585544235828-622.png
Figure: Turning on the Display option

In “off” state, the file path is printed at the insertion point, and you can set its font parameters in the window below, which opens in default settings during definition1585544243805-624.png , or when clicking on an existing external reference with 1585544249426-513.png  active:

1585544255531-795.png

If the source file has changed, you can refresh 1585544262642-681.png it, or refresh it with different parameters 1585544268044-499.png .

Statistics

Starting 1585544286269-992.png  in Tools menu opens the Statistics dialog, where User can find information about the quantities of different objects in the model.

1585544290488-987.png

Get GUID

The Get GUID function enables the query of the GUID of elements. This can be useful for identification of structural objects imported/exported via Struxml.

Picking 1585544317553-218.png  in Tools menu launches Get GUID. You needs to select teűhe elements, of which GUID you wish to know.

The pop-up window shows the General Unique IDs which can be sent to the clipboard by clicking on “Send to clipboard” button. GUIDs for analytical and physical model of a bar are different.

Analytical view:

1585544323213-325.png

Physical view:

1585544327694-917.png

If the bar is saved in struxml format, these GUIDs can be found there as well.

1585544333018-781.png

Feedback mail

In Help/FEM-Design Support you are able to reach the support easily and get answers for specific model dependant questions.

1585544346122-774.png

1585544350029-664.png

In the dialog you can decide how to receive answer, via email or phone and/or Teamviewer (remote desktop). The Help button links to a guide, how to write a request.

Local support button opens StruSoft’s support website, where the local contacts are listed.
If the Attach current model is active, the last saved model will be send to the support. If the model includes linked DWG files, those files will be attached as well.

There is an option to add more files (e.g. pictures) to the report.

Company settings

It is a very fast way to export all FEM-Design settings and libraries to any other computer. You are able to deliver your company preferences from one computer to another very easy and quickly.

1585544374923-843.png

The following items can be exported:Pick export 1585544388486-233.png  or import 1585544393106-357.png  settings in the FEM-Design Center and select the items, which wanted to be forwarded. The company settings file has *.fdcs format.
