Split Surface

(3D only) Used to perform a partial delete on a surface or solid (shape, cone, sphere, extruded surface, surface of revolution, or B-spline surface) along its rule lines, in the U or V direction. Entering a reset, changes the direction of the splitting. The result of splitting the surface or solid is two B-spline surfaces.

You can access this tool from the following:

  • Ribbon: Modeling > Surfaces > Modify Surfaces
  • Toolbox: Modify B-spline Surfaces


SettingDescription
Method Defines how the surface will be split.
  • By Point — Selecting a point to split or split and drag to make a gap.
  • By Numbers — Split into numbers of line sections in the u and v directions.
  • At Crease Iso Curves — Makes a split at a crease iso-curve.
  • Into Bezier — Splits the surface into a Bezier surface.
