//! 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.
|
|
//! RemoveIntEdges flag defines whether to remove the INTERNAL edges
|
|
//! from the result or not.
|
|
//! Warnings
|
|
//! Since the algorithm of MakeThickSolid is based on
|
|
//! MakeOffsetShape algorithm, the warnings are the same as for
|
|
//! MakeOffsetShape.
