Rebuild NURBS |
Model > 3D Power Pack |
The number of vertices in one or more selected NURBS curves or untrimmed surfaces can be changed with the Rebuild NURBS command. Reducing vertices simplifies the geometry, making it easier to manipulate, and increases the speed and ease-of-use for other objects that are based upon it.
To rebuild a NURBS curve or surface:
Select the NURBS curve or surface.
Select the command.
The Rebuild NURBS dialog box opens. Enter the number of points to use; specifying fewer points simplifies the NURBS curve or surface, but increases the difference between the original geometry and the rebuilt geometry.

Description |
|
Number of Points |
Specifies the number of points to use; for a NURBS curve, enter the number of points, which must be at least 3 |
|
U Direction |
For a NURBS surface, enter the number of points to use along the U direction; this number must be greater than 3 |
|
V Direction |
For a NURBS surface, enter the number of points to use along the V direction; this number must be greater than 3 |
|
Keep Original |
Retains the original curve or surface, and adds a new, rebuilt curve or surface |
|
Maximum Deviation |
After clicking Preview, displays the maximum deviation between the original and rebuilt surface or curve |
