//! Provides general functions to build form features.
|
|
//! Form features can be depressions or protrusions and include the following types:
|
|
//! - Cylinder
|
|
//! - Draft Prism
|
|
//! - Prism
|
|
//! - Revolved feature
|
|
//! - Pipe
|
|
//! In each case, you have a choice of 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:
|
|
//! - along a length
|
|
//! - up to a limiting face
|
|
//! - from a limiting face to a height
|
|
//! - above and/or below a plane
|
|
//! The shape defining construction of the feature can be either the
|
|
//! supporting edge or the concerned area of a face.
|
|
//! In case of the 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 to 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.
