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.
   Note:

   The 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.

   Tip:

   Turn 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.
