6.1.3.43 IfcWallType

6.1.3.43.1 Semantic definition

The element type IfcWallType defines commonly shared information for occurrences of walls. The set of shared information may include:

  • common properties within shared property sets
  • common material information
  • common material layer definitions
  • common shape representations

It is used to define a wall specification (i.e. the specific product information, that is common to all occurrences of that product type). Wall types may be exchanged without being already assigned to occurrences.

Occurrences of the IfcWallType within building models are represented by instances of IfcWall. Occurrences of the IfcWallType within structural analysis models are represented by instances of IfcStructuralSurfaceMember, or its applicable subtypes.

Informal Propositions

  1. The material assignment, if provided using the IfcRelAssociatesMaterial relationship, shall not reference the IfcMaterialLayerSetUsage. Use IfcMaterialLayerSet instead.

Last change: Improve definition split (#876) * bring back headers headers were previously removed by mistake, now bringing them back * add new lines and rename the tag add the word 'short' in it * unify newlines make exactly one newline before and two after the tag * resolving typos Because bringing back headers required to go back in time to previous version, I'm now re-resolving the issues: #861, #860, #856 by ArturTomczak on 7/16/2024, 2:07:28 PM
