#### 8.6.3.13 IfcSolidModel

| Modèle solide
| Festkörper - Modell

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.
