---Purpose: Split solids, shells and faces into parts of the
|
|
-- same topology if reconstruction level is not
|
|
-- limited.

---Purpose: constructor

|
AddShape ( me : in out; S : Shape from TopoDS);
|
|
---Purpose: add object Shape to be splitted.
|
|
-- If S is a COMPOUND or COMPSOLID, it will be
|
|
-- exploded in order to get more simple object
|
|
-- shapes.
|
|
-- Object shapes that are vertices, edges or wires

---Purpose: add cutting tool

Compute (me : in out; Limit : ShapeEnum from TopAbs

= TopAbs_SHAPE);
|
|
---Purpose: produce a result which is a compound of parts of
|
|
-- object shapes. A part can be either a vertex,
|
|
-- edge, wire, face, shell or solid.
|
|
-- By default, a part is of the same topology as an
|
|
-- object shape, else <Limit> restricts parts
|
|
-- reconstruction.
|
|
-- If <Limit> == TopAbs_VERTEX, only new vertices are
|
|
-- returned in the result

KeepShapesInside (me : in out; S : Shape from TopoDS);

|
---Purpose: remove shapes that are outside of S from result.
|
|
-- S should be an object shape.
|
|
---Warning: call it after Compute()
|
|
|
|
RemoveShapesInside (me : in out; S : Shape from TopoDS);
|
|
---Purpose: remove shapes that are inside S from result.

-- S should be an object shape.

---Purpose: return compound of faces of other shapes that are

|
-- inside <S>. <S> must have image in myImageShape.
|
|
-- <CheckClosed> makes avoid faces that do not form a
|
|
-- closed shell

CheckTool ( me: in out; S : Shape from TopoDS)

---Purpose: Return True if <S> is a tool shape. Prepare tool

---Purpose: among LE, find equal edges, choose ones to keep
