//! Describes functions to build a
|
|
//! shape corresponding to the skin of a surface.
|
|
//! Note that the term shell in the class name has the same definition
|
|
//! as that of a shell in STEP, in other words the skin of a shape,
|
|
//! and not a solid model defined by surface and thickness. If you want
|
|
//! to build the second sort of shell, you must use
|
|
//! BRepOffsetAPI_MakeOffsetShape. A shell is made of a series of
|
|
//! faces connected by their common edges.
|
|
//! If the underlying surface of a face is not C2 continuous and
|
|
//! the flag Segment is True, MakeShell breaks the surface down into
|
|
//! several faces which are all C2 continuous and which are
|
|
//! connected along the non-regular curves on the surface.
|
|
//! The resulting shell contains all these faces.
|
|
//! Construction of a Shell from a non-C2 continuous Surface
|
|
//! A MakeShell object provides a framework for:
|
|
//! - defining the construction of a shell,
|
|
//! - implementing the construction algorithm, and
|
|
//! - consulting the result.
|
|
//! Warning
|
|
//! The connected C2 faces in the shell resulting from a decomposition of
|
|
//! the surface are not sewn. For a sewn result, you need to use
|
|
//! BRepOffsetAPI_Sewing. For a shell with thickness, you need to use
|
|
//! BRepOffsetAPI_MakeOffsetShape.
