Move, rotate, or scale polygon components


You can use move, rotate, or scale polygon components in the following ways:

Transform Component also has additional constraints that Maya’s generic transformation tools do not have, such as moving perpendicular along normals.

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.


Deleting history on a polygonal object with animated vertex tweaks will result in the loss of the animation on the tweaks.

To create a history node to transform components

  1. Select the components you want to move.
  2. Select Edit Mesh > Transform Component.

    Maya creates a transformation node (polyMoveComponentType) and automatically switches to the Show Manipulator tool, allowing you to edit the node.

  3. Drag the manipulator handles to move, rotate, or scale the components, or change the settings in the Attribute Editor or the Channel Box.

    The manipulator is a standard move/rotate/scale combined manipulator, with an extra handle to switch between Local axes and World axes. Moving components along their local Y can be very useful to move components “inward” or “outward”.
