To Work With Mesh Creases

Add a Crease to a Mesh Object

1. (Optional) Specify the type of subobject to crease: right-click in the drawing area and click Subobject Selection Filter Face, Vertex, or Edge.
2. Click Modeling tab > Mesh panel > Mesh Crease drop-down > Add Crease.
3. Select the mesh edges, faces, or vertices to crease. (If you have set a subobject selection filter, only one type of subobject can be selected.)

   To remove a subobject from the selection set, Shift+click the subobject.

4. Specify the crease value:
   • Always retains the crease at all levels of smoothness.
   • Values of 1 or higher sets the level of smoothness that starts to affect the crease.

   The specified subobjects are creased. A crease is not visible on objects that have not been smoothed (the level of smoothness = 0).

Change the Crease Value of an Existing Mesh Crease (Properties window)

1. If the Properties window is not displayed, select any object. Right-click the object and select Properties.
2. Press Ctrl+click the mesh subobject that you want to modify.
   Note: If you cannot select a specific subobject, verify whether subobject selection filtering is turned on for a different subobject type. (Right-click in the drawing area and click Subobject Selection Filter.)
3. In the Properties window, Crease area, Type box, change the crease value:
   • None removes the crease and sets the subobject to the current level of smoothness.
   • Always retains the crease at all levels of smoothness.
   • By Level sets the level of smoothness that starts to affect the crease. When this setting is selected, you can specify the crease level in the Level box.

Remove a Mesh Crease

1. (Optional) Specify the type of subobject to modify: right-click in the drawing area and click Subobject Selection Filter Face, Vertex, or Edge.
2. Click Modeling tab > Mesh panel > Mesh Crease drop-down > Remove Crease.
3. Press Ctrl+click the mesh subobjects to be modified and press Enter.

   You can also use window selection to specify multiple subobjects.
