List of Prompts

The following prompts are displayed.

Specify Extension Distance

Specifies the extension length.

Expression

Enter a formula or equation to specify the length of the surface extension. See Constrain a Design with Formulas and Equations.

Modes

• Extend - Extrudes the surface in a way that tries to mimic and continue the shape of the surface.
• Stretch - Extrudes the surface without trying to mimic and continue the shape of the surface.

Creation Type

• Merge - Extends the surface the specified distance without creating a new surface.
• Append - Creates a new extension surface that is adjacent to the original surface. If the originating surface is a NURBS surface, the new extension surface will also be a NURBS surface.
