class SplitDrafts from LocOpe
---Purpose: This class provides a tool to realize the
-- following operations on a shape :
-- - split a face of the shape with a wire,
-- - put draft angle on both side of the wire.
-- For each side, the draft angle may be different.

---Purpose: Splits the face <F> of the former given shape with
-- the wire <W>. The wire is assumed to lie on the
-- face. Puts a draft angle on both parts of the
-- wire. <Extractg>, <Nplg>, <Angleg> define the
-- arguments for the left part of the wire.
-- <Extractd>, <Npld>, <Angled> define the arguments
-- for the right part of the wire. The draft angle is
-- measured with the direction <Extract>. <Npl>
-- defines the neutral plane (points belonging to the
-- neutral plane are not modified). <Angle> is the
-- value of the draft angle. If <ModifyLeft> is set
-- to <Standard_False>, no draft angle is applied to
-- the left part of the wire. If <ModifyRight> is set
-- to <Standard_False>,no draft angle is applied to
-- the right part of the wire.
