An IfcSectionedSolid is an abstract base type for solids constructed by sweeping potentially variable cross sections along a directrix.
The curve used to define the sweeping operation.
List of cross sections in sequential order along the Directrix.
The curve entity which is the underlying directrix shall have the dimensionality of 3.
The profile type shall be CURVE within the list of the profiles defining the cross sections.
The entity type for each section must be the same.
The set of cross sections and the set of cross section placements shall be of the same size.
Distance expressions must not use longitudinal, laterial or vertical offsets.
