BIMANALYTICALMODEL command

Creates an analytical model from a fully classified BIM model.

Description

Allows you to generate an analytical model from a full 3D model of a structure.

Method

The command opens the Allowed Deviations From Center Axis dialog box and starts with an automatically generated proposal but allows users to further adapt the model. For more information, see the related article Allowed deviations from center axis dialog box.

The automatic proposal will try to minimize rigid links (eccentricities) as much as possible by shifting, extending and even rotating some axis lines. The number of such changes can be controlled by the deviation settings.

Note: The generated proposal can be modified afterward by using the options inside the Allowed Deviations From Center Axis Dialog Box.

Options within the command

Visual settings
Opens the Visual settings dialog box. Allows to tick and untick different features of axes and nodes to highlight (in yellow) the axes and nodes that match these features. Also, the size of the disks representing the nodes can be changed from here.
Recalculate
Propagates the effect of a local change further, allowing modifications in the complete model. It will launch a global solution that again tries to minimize rigid links, respecting the changes made.
Export and exit
Exports the model to an IFC (*.ifc) or CIS/2 (*.stp) file.

Options in a node

Select connected axes
Selects the axes connected to the node.
Remove
Removes the node and the connected axes will be disconnected.
Connect from axes
Connects the node to a chosen axis (axes).
Disconnect from axes
Disconnects the node from a chosen axis (axes).
Auto split
Automatically splits the node into two nodes.
Split along axis
Manually splits the node along an axis.
Merge
Merges two or more selected nodes together.

Options in an axis

Select connected nodes
Selects the nodes connected to the axis.
Remove
Removes the axis.
Connect to node
Connects the axis to a chosen node.
Disconnect from node
Disconnects the axis from a chosen node.
Add restrictions
Adds a restriction on the axis.
The restriction you can add depends on the restrictions that are already imposed.
If there are no restrictions yet, you can add the following restrictions:
  • Parallel to the centerline.
  • Inside profile bounds.
  • To closest midplane.
  • To closest base position.
  • To center.
  • No length extension.
Relax restrictions
Relaxes a restriction on the axis.
The restriction you can relax depends on the restrictions that are imposed.
Mostly these will be the restrictions that you can relax:
  • Inside profile bounds.
  • Outside profile bounds.
  • Non-parallel.
  • Allow length extension.
