Moving Vertices and Tangents

You can move vertices and tangents using the Move option of the Edit Mode box:

- To move a vertex or tangent in any direction, select Move. Click the vertex or tangent and drag.
- To move selected vertices in any direction, select Move. Click one of the selected vertices and drag.
- To ensure better continuity on a garbage mask, automatically adjust tangents as you move vertices or scale the mask. Enable Auto Adjust and drag a vertex. To toggle temporarily enable or disable Auto Adjust, press and hold G and then drag a vertex. Auto Tangents must be enabled to use the Auto Adjust feature.
- To keep tangent handles an equal length, Ctrl+Alt-drag one vertex handle to automatically change the length of the other tangent handle at the same time.

You can use the Vertices tab to move vertex and tangent positions.

The Selection fields display the current position of the vertex. If multiple vertices are selected, the position displayed is of the vertex that is closest to the initial vertex created in the mask.

Depending on the Transformation and Pivot Type options, you can move sets of selected vertices by editing the Translate, Scale, Shear and Rotation fields. See Creating a Localized Pivot Point for Vertices.

You can move tangent handles independently. See Breaking Tangents.
