To Apply a Soft or a Hard Crease to a Control Mesh
1. Create or import a shape.
2. Select one or more mesh elements on the control mesh.
3. In the Crease group, select Hard or Soft.
4. Adjust the crease value using the slider or the spin box.
Alternatively, right—click the graphics window and select to apply a 100% hard crease. If you apply a crease to an already creased mesh element, the crease gets removed.
