Options

The following options are available:

:FACE_PART - specifies the name of the new face part.
:FACE_TO_UNTRIM - specifies the actual face to be untrimmed.
:ENLARGEMENT - specifies the extension factor for the untrimmed face geometry. For example, a factor of 2 produces an untrimmed face part twice as large (if geometrically and topologically permissible) as the trimmed face.
:USE_FACE_BOX - specifies that a face box should be applied to the face. This face box serves as a bounding box around the face for the untrim operation. If you specify :OFF for the face box option, the entire underlying surface of the face will be regenerated.
:PREVIEW - enables you to preview the result of the untrim operation.

When to use

You can use the UNTRIM action to identify the underlying surface of a face produced by a trim operation and/or to extend such a face along its underlying surface.

Example

The following example untrims a face part named p2. the enlargement factor is 1.5. The face box is disabled.

UNTRIM_DIALOG :FACE_PART "/p2" :FACE_TO_UNTRIM (GPNTWC -24.443956 -28.691782 3.350773 "vport1") :ENLARGEMENT 1.5 :USE_FACE_BOX :OFF
