SURFEXTEND (Command)

Lengthens a surface by a specified distance.

Access Methods

Button

 Toolbar: Modeling tool set Surfaces - Edit tool group (expanded) Surface Extend

 Menu: Draw 3D Modeling Surfaces Extend

Summary

The extension surface can be merged (part of the original surface) or appended (creating a second surface adjacent to the original surface).

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.
