Detailed Description
Describes functions to build hollowed solids. A hollowed solid is built from an initial solid and a set of faces on this solid, which are to be removed. The remaining faces of the solid become the walls of the hollowed solid, their thickness defined at the time of construction. the solid is built from an initial solid <S> and a set of faces {Fi} from <S>, builds a solid composed by two shells closed by the {Fi}. First shell <SS> is composed by all the faces of <S> expected {Fi}. Second shell is the offset shell of <SS>. A MakeThickSolid object provides a framework for:
- defining the cross-section of a hollowed solid,
- implementing the construction algorithm, and
- consulting the result.

Constructs a hollowed solid from the solid S by removing the set of faces ClosingFaces from S, where: Offset defines the thickness of the walls. Its sign indicates which side of the surface of the solid the hollowed shape is built on;.
- Tol defines the tolerance criterion for coincidence in generated shapes;
- Mode defines the construction type of parallels applied to free edges of shape S. Currently, only one construction type is implemented, namely the one where the free edges do not generate parallels; this corresponds to the default value BRepOffset_Skin; Intersection specifies how the algorithm must work in order to limit the parallels to two adjacent shapes:
- if Intersection is false (default value), the intersection is calculated with the parallels to the two adjacent shapes,
- if Intersection is true, the intersection is calculated by taking account of all parallels generated; this computation method is more general as it avoids self-intersections generated in the offset shape from features of small dimensions on shape S, however this method has not been completely implemented and therefore is not recommended for use;
- SelfInter tells the algorithm whether a computation to eliminate self-intersections needs to be applied to the resulting shape. However, as this functionality is not yet implemented, you should use the default value (false);
- Join defines how to fill the holes that may appear between parallels to the two adjacent faces. It may take values GeomAbs_Arc or GeomAbs_Intersection:
- if Join is equal to GeomAbs_Arc, then pipes are generated between two free edges of two adjacent parallels, and spheres are generated on "images" of vertices; it is the default value,
- if Join is equal to GeomAbs_Intersection, then the parallels to the two adjacent faces are enlarged and intersected, so that there are no free edges on parallels to faces. Warnings Since the algorithm of MakeThickSolid is based on MakeOffsetShape algorithm, the warnings are the same as for MakeOffsetShape.
