# Parametric model (Beta)

Contents

The parametric model is an editor module, where the User can create parametrized model as templates. The templates later can be imported into the Structure module with customized settings.

This module can be found in the command center.

# Available structural and analytical elements

In the first version of the parametric model module the user can use point and straight line objects, like point and line foundations, bars, point and line supports, and fictitious bars.

# Parameter tab

The parameter tab is where the tools placed to parametrize the model element’s number and placement.

## Base rays and base planes

These objects can be used as the frame of the parametric model. Structural and analytical elements can be attached them.

For 3D parametric models it’s advised to use only base planes, and for 2D models base rays should be preferred.

The following example, which is a simple roof structure with columns, shows a practical way to use base planes and base rays. The base planes defines the plane where the supports, the columns will be placed, the bottom and the top level and the first and last plane of the roof structure. The base rays will defines the beams x’ direction (and for locking, see on Lock chapter).

## Grids

Grids are used to create iterative patterns, like a series of columns or an array of point foundations.

With this function the User can create one, two or three dimensional grids:

Structural and analytical elements can be attached to the grid. The attachable elements should be fit in one cell of the grid:

The user can draw anywhere in the cells, it will be attached to that grid.

The grids can be warped in every possible way by the corner points.

If the grid's cell is triangular shape the structural element cannot be attached to the triangular edges.

The User can set the number of cells in one direction by any given numbers or parameters:

The User can set where he/she wants to multiply structural objects on the grid:

Using the Local y’ axis option to follow the objects local y’ axis in the grid after the structural element assigned to grid.

## Locks

Locks are used to bound nodes of structural elements, analytical elements, base lines and grids to the cross points of base elements. The locked objects are marked with the lock symbol in the model space.

Cross points can be a intersections of two base line, an intersection of a base line and base plane and a cross point of three base plane. The following example shows how to define the middle beam position with lock object, simply The base ray and base plane intersection will be the position of the middle beam.

If the base objects are moved, the locked objects are moving with them

## Constraints

Constrains are used to set distances between parallel base objects.

The following example shows how to use the parameters on a practical example.

Parameters

Parameters are used to control the parametric model. It can be created new parameters directly in the parameter dialogs or indirectly from parametric objects’ dialogs (grid and constraint).

If one of the parameters (which are assigned to the parametric model) changed the modifications will automatically apply to the paramteric model.

## Import parametric models to structure module

The parametric model can be imported to 3D modules by

• Tools / Apply parametric model
• Edit / Paste file
• Open (file with *.prm extension)

After selecting the .prm file the parameter dialog will appear where the previously defined parameters can be set and with that parameters the model will be applied.
