Some modeling tools cannot operate on a NURBS object. To use these tools, you would have to transform your NURBS object into a polygonal model. This transformation is done through the Information tool of the Control Panel. (See chapter User Manual/Tools/Control Panel/Get info.) However, keep in mind that a NURBS model transformed into a polygonal object cannot be transformed back into a NURBS object. So do not use these tools if you need your models to remain as NURBS objects.
Here is the list of these tools and their action on a NURBS object:
Tool: |
Result: |
Thickness : |
Displays a message indicating that this tool cannot be applied to a NURBS surface. |
Delete : |
No effect. |
Cut : |
Performs the operation but transforms the NURBS object into a polygonal model. |
Filleting : |
No effect. |
