Invert Surface

Modify Surface Invert

The Invert Surface command enables you to change the parameterization or invert the normal of a surface. Two different modes are available in the Mode drop-down list. You can:

Modify the surface parameterization (U/V option), which means you can:
- Invert its parameterization along the u parametric direction (the edge u=0 becomes the edge u=1 and vice versa).
- Invert its parameterization along the v parametric direction (the edge v=0 becomes the edge v=1 and vice versa).
- Exchange the surface parametric directions (the edge u=0 becomes the edge v=0 and vice versa).
Invert the orientation of the surface normal (Normal option).

Associative Mode
The surfaces created using this command can be associative: associative surfaces are Skins, that is open solids, retaining a link to the base entities, so that if you modify the base entities the surfaces will be modified accordingly; they have a history and are displayed in the Model Structure. See "Associative Surfaces (Skins) for details.

Conversion to NURBS
If the selected surface is not a NURBS, you will be asked to confirm whether you want to convert it into a NURBS (unless you have deselected the Ask before converting check box).
