Convert a trimmed surface into an untrimmed surface with the same shape
 
 
 

Attempts to reshape a NURBS surface so its actual shape resembles its trimmed shape.

  1. Choose Surface Edit > Trim > Trim Convert .
  2. Click a four-sided trimmed surface.
    NoteThe Trim convert tool does its best job to match the shape of the trimmed surface with an untrimmed surface. In most cases, an exact match will be impossible.
    TipTurn on the Show Edge Deviations and Show Surface Deviations options to attach deviation locators to the resulting surface to see how much the new surface differs from the original.
