Profile Definitions

Lately I am reading up on Profile Definitions, specifically Parameterized Profiles, but I can’t quite seem to grasp the subject fully. As I understand things now, certain geometric profiles are standard and have thus received a Parameterized Profile Def. I’ve managed to find the following profiles, which I categorized in three groups:

‘Advanced’ shapes:

  • I-shape (both symmetric and asymmetric)
  • C-shape
  • L-shape
  • T-shape
  • U-shape
  • Z-shape

Plain shapes:

  • Circle (both solid and hollow)
  • Ellipse
  • Rectangle (both solid, hollow ánd rounded)
  • Trapezium

Other:

  1. (Arbitrary) Hollow Core profile
  2. Double T profile
  3. Mechanical profiles

When you combined two or more profiles, IfcCompositeProfileDef applies.

My aim is to check and report the parameters in the Parameterized Profile Def. So far, no luck. Does anyone here have any experience on the subject?

PS: While digging, I found the following issues on the documentation page of IFC4ADD2TC1:

For closure, I think the figure references have been fixed. Please bump if there are still issues.
