|summary||non vertical walls shall not be exchanged as instances of IfcWallStandardCase|
The value range of geometric representations for instances of IfcWallStandardCase is restricted (and written in the IFC specification). In addition the following requirement has to be met:
- instances of IfcWallStandardCase shall be extruded vertically, i.e. the wall body extrusion direction shall be along the positive z axis of the local placement of the wall and along the global positive Z axis.
