class MakeShell from BRepBuilderAPI inherits MakeShape from BRepBuilderAPI
|
|
|
|
---Purpose: 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.
