Offset Surface

Use it!

(3D only) Used to construct a B-spline surface by offsetting an extruded surface, surface of revolution or a B-spline surface.

Tool Setting	Effect
Distance	If on, sets the offset distance in the surface normal direction.
Make Copy	If on, the element is copied and the original is not manipulated.

To construct an offset surface

1. Select the Offset Surface tool.


2. Identify the surface.


3. Enter a data point.
   If Distance is off, this data point defines the distance and direction to offset the surface.
   If Distance is on, this data point defines the direction only.

   Left: Identify the surface (1) then define the direction and/or distance (2). Right: The completed offset surface.
