IFC representation for Box #12

Closed Supporting closed 8 years ago

Supporting commented 8 years ago

Currently, Boxes get tessellated and are represented as IfcConnectedFaceset. Find a suitable representation that represents the box more efficient and information conserving.

A RVM Box could be represented using the IfcBlock entity. The tool support for this entity is however poor:

FZK Viewer 4.5
~~Tekla BIMsight 1.9.5~~
~~Solibri Model Viewer 9.5.24~~
~~Autodesk Navisworks 2014~~
IfcOpenShell 0.4.0

Here a simple generated IFC file used for testing: box-block.zip

A better alternative is to map to an extruded rectangle using IfcExtrudedAreaSolid + IfcRectangleProfileDef :white_medium_square:

Tool support is good:

FZK Viewer 4.5
Tekla BIMsight 1.9.5
Solibri Model Viewer 9.5.24
Autodesk Navisworks 2014
IfcOpenShell 0.4.0
