Moving one or several vertices on a polygon along the direction of their normals is a convenient, easy to manage method of editing a polygon surface.
- Select vertices.
- Select the Move Tool.
- Do one of the following:
- Ctrl + middle-drag left to pull vertices in along their normals.
- Ctrl + middle-drag right to push vertices out along their normals.
To move polygon vertices along their normals using the Move Normal Tool
- Select vertices in the scene view.
- In the Toolbox, double click the Move tool to display its option panel.
- In the options panel, set Move to Normal and turn on Update (UVN) Triad.
- Drag the
UVN (Move Normal Tool) manipulator to move the selected vertices.
Note: Avoid tweaks (moving CVs, moving polygon components with Move, Rotate or Scale) on objects with history. If you tweak an object with history, the tweak is applied to a specific component ID. Subsequent changes to the object’s history can cause the component IDs to change, altering the effect of the tweak.For example, if you revolve a curve to create a surface, then tweak CV number 3 on the surface, the tweak will always apply to CV number 3. If you later change the revolve node attributes to reduce the number of segments on the surface, the CV that you tweaked will now have a new number, and the tweak will no longer be applied to it. The tweak will be applied to the CV that is now number 3, which may be in a different location on the surface.
