To Work With Mesh Creases

Add a Crease to a Mesh Object

(Optional) Specify the type of subobject to crease: right-click in the drawing area and click Subobject Selection Filter Face, Vertex, or Edge.
Click Mesh tabMesh panelAdd Crease. Find
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.
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).

If the Properties palette is not displayed, select any object. Right-click the object and select Properties.
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.)
In the Properties palette, 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.

(Optional) Specify the type of subobject to modify: right-click in the drawing area and click Subobject Selection Filter Face, Vertex, or Edge.
Click Mesh tabMesh panelRemove Crease. Find
Press Ctrl+click the mesh subobjects to be modified and press Enter.
You can also use window selection to specify multiple subobjects.
