8.8.3.39 IfcSolidModel
ABSTRACT This definition may not be instantiated
8.8.3.39.1 Semantic 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.
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. Entity adapted from solid_model defined in ISO 10303-42. New entity in IFC1.58.8.3.39.2 Entity inheritance

8.8.3.39.3 Attributes
| # | Attribute | Type | Description |
|---|---|---|---|
| IfcRepresentationItem (2) | |||
| LayerAssignment | SET [0:1] OF IfcPresentationLayerAssignment FOR AssignedItems |
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. The inverse attribute LayerAssignments has been added. The inverse attribute LayerAssignment has been restricted to max 1. Upward compatibility for file based exchange is guaranteed. |
|
| StyledByItem | SET [0:1] OF IfcStyledItem FOR Item |
Reference to the IfcStyledItem that provides presentation information to the representation, e.g. a curve style, including colour and thickness to a geometric curve. The inverse attribute StyledByItem has been added. |
