Entity definition

An IfcSolidModel represents the 3D shape by different types of solid model representations. It is the common abstract supertype of Boundary representation, CSG representation, Sweeping representation and other suitable solid representation schemes.

NOTE  Definition according to ISO/CD 10303-42:1992
A solid model is a complete representation of the nominal shape of a product such that all points in the interior are connected. Any point can be classified as being inside, outside, or on the boundary of a solid. There are several different types of solid model representations.
NOTE  Entity adapted from solid_model defined in ISO 10303-42.
HISTORY  New entity in IFC1.5

Attribute inheritance
S[0:1]Assignment of the representation item to a single or multiple layer(s). The LayerAssignments can override a LayerAssignments of the IfcRepresentation it is used within the list of Items.
IFC2x3 CHANGE  The inverse attribute LayerAssignments has been added.
IFC4 CHANGE  The inverse attribute LayerAssignment has been restricted to max 1. Upward compatibility for file based exchange is guaranteed.
S[0:1]Reference to the IfcStyledItem that provides presentation information to the representation, e.g. a curve style, including colour and thickness to a geometric curve.
IFC2x3 CHANGE  The inverse attribute StyledByItem has been added.
