|
//! BRepFeat is necessary for the
|
|
//! creation and manipulation of both form and mechanical features in a
|
|
//! Boundary Representation framework. Form features can be depressions or
|
|
//! protrusions and include the following types:
|
|
//! - Cylinder
|
|
//! - Draft Prism
|
|
//! - Prism
|
|
//! - Revolved feature
|
|
//! - Pipe
|
|
//! Depending on whether you wish to make a depression or a protrusion,
|
|
//! you can choose your operation type between the following:
|
|
//! - removing matter (a Boolean cut: Fuse setting 0)
|
|
//! - adding matter (Boolean fusion: Fuse setting 1)
|
|
//! The semantics of form feature creation is based on the
|
|
//! construction of shapes:
|
|
//! - for a certain length in a certain direction
|
|
//! - up to a limiting face
|
|
//! - from a limiting face at a height
|
|
//! - above and/or below a plane
|
|
//! The shape defining the construction of a feature can be either a
|
|
//! supporting edge or a concerned area of a face.
|
|
//! In case of supporting edge, this contour can be attached to a face
|
|
//! of the basis shape by binding. When the contour is bound to this face,
|
|
//! the information that the contour will slide on the face becomes
|
|
//! available to the relevant class methods. In case of the concerned
|
|
//! area of a face, you could, for example, cut it out and move it at
|
|
//! a different height, which will define the limiting face of a
|
|
//! protrusion or depression. Topological definition with local
|
|
//! operations of this sort makes calculations simpler and faster
|
|
//! than a global operation. The latter would entail a second phase of
|
|
//! removing unwanted matter to get the same result.
|
|
//! Mechanical features include ribs - protrusions - and grooves (or
|
|
//! slots) - depressions along planar (linear) surfaces or revolution surfaces.
|
|
//! The semantics of mechanical features is based on giving
|
|
//! thickness to a contour. This thickness can either be unilateral
|
|
//! - on one side of the contour - or bilateral - on both sides. As in
|
|
//! the semantics of form features, the thickness is defined by
|
|
//! construction of shapes in specific contexts.
|
|
//! However, in case of mechanical features, development contexts
|
|
//! differ. Here they include extrusion:
|
|
//! - to a limiting face of the basis shape
|
|
//! - to or from a limiting plane
|
|
//! - to a height.
