Modifying surfaces
Use the Modify Surface menu to edit surfaces. You can also change surface parameters, copy parameters from one surface to another, or move points on a surface to change its shape.
By default, the appearance of a surface is based on its surface parameters. By adjusting the parameters, you change the surface. However, if you modify points on the surface, the following geometric parameters are frozen:
In addition, for extrusions and revolutions, the surface is no longer linked to the curve from which it was generated. Instead, you control the shape of the surface by manipulating its points. To enable the parameters and the curves again, you can un-freeze the surface; the surface is redrawn based on its parameters and any new or moved points are ignored. Edited point colors or texture coordinates are also ignored.
