To Extend a Surface

1. Click Modeling tab > Surface panel > Surface Extend.
2. Select one or more surface edges and press Enter.
3. Enter m (Modes) and specify the general shape of the extension:
   • To mimic and continue the shape of the surface based on the vector of adjacent edges: Enter e (Extend).
   • To extend the surface independent of the adjacent edges: Enter s (Stretch).
4. Specify whether the surface is merged or appended:
   • To merge the new surface to the original surface: Enter m (Merge).
   • To append the surface and create a separate surface: Enter a (Append).
5. Enter the distance of the extension and press Enter.
