To Move or Rotate the Control Mesh
1. Create or import a shape.
2. Use the handles, planes, and the rings of the dragger to move or rotate the control mesh. Press ALT and then drag to extrude the selected control mesh.
3. If you have selected multiple mesh elements, you can control their movement with respect to one another using the options in the Manipulation group:
◦ Constant—Moves all the selected mesh elements by the same distance.
◦ Linear—Moves all the selected mesh elements with a linear interpolation.
◦ Smooth—Moves all the selected mesh elements with a smooth interpolation.
