Surface Extrude The Surface Extrude tool will allow you to take a 2D object and turn it into
a 3D object.
Surface Trim The Surface Trim tool lets you trim one or several surfaces to other surfaces.
You can also type SURFTRIM .
Surface Untrim Surface Untrim does exactly what it says. It reverses a trim operation. You
can also type SURFUNTRIM .
Surface Fillet With the Surface Fillet tool, you can join one surface to another with an inter-
mediate rounded surface (see Figure 23.35).
Offset Surface Offset, like the Surface Trim tool, mimics its 2D counterpart. It will create a
new surface that is parallel to the original. When you start the Surface Offset tool from the
Surfaces - Create tool group and select a surface, you'll see arrows indicating the direction
of the offset. You can type F ↵ to fl ip the direction of the offset. Enter a distance for the offset
and press ↵ to create the offset surface (see Figure 23.36). You can also type SURFOFFSET .
