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

Cut or trim surfaces

Trim a regular surface then convert a four-sided trim region into an untrimmed surface

Trims a surface and converts the trimmed surface to a natural surface with the same shape, in one operation.

1. Choose Surface Edit > Trim > Trim Convert
2. Select a surface. (You can only trim convert one surface at a time.)
3. Click on the regions to keep. If 3D Trimming is turned on, you can first select curves to project onto the surface in order to define trim regions.

   Crosshairs appear on the selected regions. The size of those region selectors can be modified through the option window.

   

4. Click the Convert button

   The tool trims the surface, then attempts to convert the trimmed surface to a new surface with natural boundaries.

   Note If the trimmed surface is not four-sided, the system issues an error and asks you to redefine the trim region.

   A locator shows the maximum deviation between the original and the converted surface.

   

5. If you are not happy with the result, click the Revert button to get back the original untrimmed surface.
