class MakeOffset from BRepOffsetAPI inherits MakeShape from BRepBuilderAPI
|
|
|
|
---Purpose: Describes algorithms for offsetting wires from a set of
|
|
-- wires contained in a planar face.
|
|
-- A MakeOffset object provides a framework for:
|
|
-- - defining the construction of an offset,
|
|
-- - implementing the construction algorithm, and
|
|
-- - consulting the result.
