: SURFACE : Change:RefineShortcut
: NoneThis command increases the number of control points in a B-spline or Bézier surface control mesh.
A parameter box appears requesting the directions in which the surface should be refined. Refining doubles the original number of control points in the given direction(s). Repeating the command would further double the number.
The command can also be used to refine several surfaces in an element at once. Is this case, the command asks for the maximum allowed patch size. Any surface containing patches larger than the given value will then be refined, but not the others.
Increasing the number of points makes the surface more complicated and therefor slower to work with. This command may prove useful when using other surface commands such as Bend and Twist and also when trimming surfaces. If a trim operation fails, refining one or both surfaces may enable DeskArtes to perform the trim operation. In particular surfaces created by the command SURFACEÞDesign:Primitive are in their simplest form possible which can lead to trimming difficulties.
