Creates a closed polyline or spline object that is offset at a specified distance from the edges of a selected planar face on a 3D solid or surface.
You can offset the edges of a planar face on a 3D solid or surface. The result is a closed polyline or spline that is located on the same plane as the selected face or surface, and can be inside or outside the original edges.

The following prompts are displayed.
Select face
Specifies a planar face on a 3D solid or surface.
Through point
Creates an offset object that passes through the specified point. This point is always projected line-of-sight onto the plane of the selected face.
Distance
Creates an offset object at a specified distance from the edges of the selected face.
- Specify distance
-
Enter the offset distance, or press Enter to accept the current distance.
- Specify point on side to offset
-
Specify a point location to determine whether the offset distance is applied inside or outside the edges of the face.
Corner
Specifies the type of corners on the offset object when it is created outside the edges of the selected face. External and internal corners create rounded corners differently depending whether the corners are concave or convex.
- Sharp
-
Creates sharp corners between offset linear segments.
- Rounded
-
Creates rounded corners between offset linear segments, using a radius that is equal to the offset distance. The radius of the generated arcs is equal to the specified offset distance.
