Optimal Draw Restricts the wireframe display to only show the original mesh cage edges, rather than the subdivided result, to help visualization. Subsurf UV When enabled, the UV maps will also be subsurfed (i.e. Blender will add “virtual” coordinates for all sub-faces created by this modifier).

To view and edit the results of the subdivision (“isolines”) while you’re editing the mesh, you must enable the Editing Cage mode by clicking in the gray circle in the modifier panel header (next to the arrows for moving the modifier up and down the stack). This lets you grab the points as they lie in their new subdivided locations, rather than on the original mesh.

You can use ⇧ Shift O if you are in Object mode to switch Subsurf On or Off in both the Object mode and at rendering. To only turn the subsurf view on/off in Object mode (to reduce lag), press ⇧ Shift Alt O. The Subsurf level can also be controlled via Ctrl 1 to Ctrl 4. but this only affects the visualization sub-division level.

A subsurfed mesh and a NURBS surface have many points in common such as they both rely on a “coarse” low-poly “mesh” to define a smooth “high definition” surface, however, there are notable differences:

  • NURBS allow for finer control on the surface, since you can set “weights” independently on each control point of the control mesh. On a subsurfed mesh you cannot act on weights (except for edges crease, see bellow).
  • Subsurfs have a more flexible modeling approach. Since a subsurf is a mathematical operation occurring on a mesh, you can use all the modeling tools and techniques described in the chapter on mesh modeling. There are more techniques, which are far more flexible, than those available for NURBS control polygons.

Since Subsurf computations are performed both real-time, while you model, and at render time, and they are CPU intensive, it is usually good practice to keep the subsurf Levels low (but non-zero) while modeling, and higher while rendering ( Render Levels ).
