deferred class ModifyShape from BRepBuilderAPI inherits MakeShape from BRepBuilderAPI
|
|
|
|
---Purpose: Implements the methods of MakeShape for the
|
|
-- constant topology modifications. The methods are
|
|
-- implemented when the modification uses a Modifier
|
|
-- from BRepTools. Some of them have to be redefined
|
|
-- if the modification is implemented with another
|
|
-- tool (see Transform from BRepBuilderAPI for example).
|
|
-- The BRepBuilderAPI package provides the following
|
|
-- frameworks to perform modifications of this sort:
|
|
-- - BRepBuilderAPI_Copy to produce the copy of a shape,
|
|
-- - BRepBuilderAPI_Transform and
|
|
-- BRepBuilderAPI_GTransform to apply a geometric
|
|
-- transformation to a shape,
|
|
-- - BRepBuilderAPI_NurbsConvert to convert the
|
|
-- whole geometry of a shape into NURBS geometry,
|
|
-- - BRepOffsetAPI_DraftAngle to build a tapered shape.
