7.11.5.1.1 Semantic definition

Base quantities that are common to the definition of all occurrences of footings.

7.11.5.1.2 Applicable entities

7.11.5.1.3 Properties

Name Data Type Description
Length IfcQuantityLength

The length of the object.

Not taking into account any cut-out's or other processing features. For strip footings it is measured along the path, for other footings it is one of the horizontal dimensions. It should only be provided, if it is constant.

Width IfcQuantityLength

The width of the object. Only given, if the object has constant thickness (prismatic).

For strip footings it is measured perpendicular to the footing path (or longitudial axis). For other footings it is one of the horizontal dimensions. It should only be provided, if it is constant.

Height IfcQuantityLength

Characteristic height

Total nominal height of the footing. It should only be provided, if it is constant.

CrossSectionArea IfcQuantityArea

Total area of the cross section (or profile) of the object.

OuterSurfaceArea IfcQuantityArea

Total area of the surfaces of the object (not taking into account the end cap areas), normally generated as perimeter * length in case of extrusions.

GrossSurfaceArea IfcQuantityArea

Total gross area of the object, normally generated as perimeter * length + 2 * cross section area. It is the sum of OuterSurfaceArea + (2 x CrossSectionArea) and shall only be given, if the OuterSurfaceArea and CrossSectionArea cannot be established separately.

GrossVolume IfcQuantityVolume

Total gross volume of the object. Openings, recesses, enclosed objects and projections are not taken into account.

NetVolume IfcQuantityVolume

Total net volume of the object, taking into account possible processing features (cut-out's, etc.) or openings and recesses.

GrossWeight IfcQuantityWeight

Total Gross Weight of the object without any add-on parts and not taking into account possible processing features (cut-out's, etc.) or openings and recesses.

NetWeight IfcQuantityWeight

Total net weight of the object without add-on parts, taking into account possible processing features (cut-out's, etc.) or openings and recesses.
