|summary||use of the same parameterization for profiles in IFC2x2 and IFC2x3 based on center of bounding box|
DescriptionBetween IFC2x2 and IFC2x3 the definition on how the parameter of all asymmetric (in at least on direction) parameterized profile definitions are applied have changed:
- in IFC2x2 all parameter have beed applied relative to the center of gravity,
- in IFC2x3 all parameter are applied relative to the geometric center (the center of the bounding rectangel), the offset of the center of gravity in now only for informational purposes.
NOTE: There is no schema change between 2x2 and 2x3, only a change in the convention on how the parameters are applied.
The following entities are effected by this agreement:
