Crease Edges
 Subdivision > Crease Edges
 

Description:

      The Crease Edges (Subdivision > Crease Edges) command allows you to change the way an object is subdivided. Creasing an edge lessens the smoothing effect of the subdivision algorithm for that edge, resulting in a creased or hardened line on the subdivided object. In terms of the subdivision algorithm, a crease causes the vertices of that edge to be less displaced, i.e. less smoothed, than they would otherwise be. Creased edges have a cumulative effect on the vertices they share, so a vertex with three or more attached edges creased will be in the same place on the subdivided shape as it was on the control mesh, while a vertex with none of its edges creased will be smoothed normally.  Experiment with this command to learn how to use it effectively.


Notes:

- A crease can be removed from an edge with the Uncrease Edge (Subdivision > Uncrease) command.

- Crease Edge only works in edge selection mode.
