Using the Invert Surface command you can very easily and interactively change the parameterization of a surface. After starting the command, proceed as follows.
1 | Select the surface to be modified.![]() Remember you can always change the selected surface (for example if you selected the wrong one by mistake) by clicking on Surfaces and selecting a new surface (or by right-clicking on Surfaces, choosing Reset in the context menu and selecting a new surface). 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). |
2 | In the Mode drop-down list, select
U/V. Two arrows show up to display the two parametric directions, while an
Exchange U/V item is added to the Selection List.![]() You can then choose whether to invert a parametric direction or to exchange them.
