Drive Surfaces
Introduction
The Drive Surfaces are a selection of one or more surfaces upon which
the toolpath is created. Most important for the selection is the normal
direction of the surfaces/faces. Since a surface has two sides, the toolpath
is determined to be located on the front side of the surface. The front
is the side the surface normal protrudes from. For solids, the normal
direction is usually easily defined, it points outside
of the model. An exception is when a part file is imported or converted
and the surface normal directions change. Changing the surface normal
direction is accomplished using the Reverse Surface Normal
- Drive Surfaces - enables selection mode for you to select geometry upon which the toolpath is generated.
- Drive Surfaces Offset -
creates a 3D offset of the drive surface geometry. This is used to
leave stock remaining on the part.
Reversing the Surface Normal Direction
Reversing the surface normal direction for multiaxis drive surfaces is done during geometry selection, as explained in the Selection Manager.
