And once again, all of the polygonal modeling tools function with subdivision surfaces. Fitting Using the new Fit operator, artists can now create a new curve or surface based on an existing one, and specify the subdivisions and the degree of the surface. Snipping The new Snip feature enables the artist to cut a surface along any isoline. You can now add and remove knots simply by clicking at any location along a curve or surface. Picking The picking process for inputs for many surface modeling tools has been simplified and generalized.
Artists can tweak inputs immediately after picking isolines and other surface curves.
The surface continuity manager is now applied automatically when a surface mesh is assembled. Excluding Points You can exclude points from surface continuity management by selecting them either prior or post assembly, enabling the creation of holes for eyes, mouth, and other features. Extracting Curves You can extract a curve such as an isoline from across multiple subsurfaces on a surface mesh. Reference Planes Reference Planes enable artists to define arbitrary reference planes to help build objects quickly and precisely. You can create multiple reference planes and specify which one is active at any time.
