class Ifc4x1::IfcDimensionCount : public IfcUtil::IfcBaseType

Definition from ISO/CD 10303-42:1992: A dimension count is a positive integer used to define the coordinate space dimensionality.

The IfcDimensionCount is restricted to have the dimensionality of either 1, 2, or 3 - the WR1 had been added as an addition to the ISO 10303:42 entity dimension_count. In contrary to the ISO 10303:42 constraint, that all geometric representation items within a geometric representation context are forced to have the same dimension count, the IFC geometry allows mixed dimensions, particularly when defining the boundary of planar surfaces.

NOTE Corresponding ISO 10303 type: dimension_count, please refer to ISO/IS 10303-42:1994, p. 14 for the final definition of the formal standard.
