class MakePipe from BRepFeat inherits Form from BRepFeat
---Purpose: Constructs compound shapes with pipe
-- features. These can be depressions or protrusions.
-- The semantics of pipe feature creation is based on the construction of shapes:
-- - along a length
-- - up to a limiting face
-- - from a limiting face to a height.
-- The shape defining construction of the pipe feature can be either the supporting edge or
-- the concerned area of a face.
-- In case of the supporting edge, this contour
-- can be attached to a face of the basis shape
-- by binding. When the contour is bound to this
-- face, the information that the contour will
-- slide on the face becomes available to the relevant class methods.
-- In case of the concerned area of a face, you
-- could, for example, cut it out and move it to a
-- different height which will define the limiting
-- face of a protrusion or depression.

Modify : Boolean from Standard)
---Purpose : A face Pbase is selected in the
-- shape Sbase to serve as the basis for the
-- pipe. It will be defined by the wire Spine.
-- Fuse offers a choice between:
-- - removing matter with a Boolean cut using the setting 0
-- - adding matter with Boolean fusion using the setting 1.
-- The sketch face Skface serves to determine
-- the type of operation. If it is inside the basis
-- shape, a local operation such as glueing can be performed.

Add(me: in out; E: Edge from TopoDS; OnFace: Face from TopoDS)
---Purpose: Indicates that the edge <E> will slide on the face
-- <OnFace>. Raises ConstructionError if the face does not belong to the
