# Crease Sharp

This operator will crease edges in the mesh whenever an edge from that list meets the **Sharpness** angle threshold. When activated, the operator will trigger immediately and to change its result you have to use the `F9` hotkey to show the redo panel.

You can set the crease strength using the **Factor** property. If you want, you can set the crease only to selected edges by enabling the **Selected Only** toggle.

This operator is primarily designed to work with random results that uses the subdivision modifier or if the **Copy All Modifiers** toggle is turned in the add-on **Settings** with the randomized meshes inheriting the subdivision modifier from the source mesh.

By creasing the sharp edges in a subsurfed mesh, you will make the effect of the subdivision modifier sharper in these areas.
