Untrimming Objects

You can untrim cut objects, that is, you can restore the underlying geometry or remove the boundary of a cut object.

You can use two commands:

  • Uncut creates a feature. You can select as the input multiple cut edges or points of the same object.
  • Uncut (modifying) creates a datum. It directly modifies the input geometry and has no associativity. You can select as the input multiple cut edges or points of several objects.

See the following table to identify the input objects for a certain action:

Action Input Object
Restore the underlying surface Standalone face
Remove the edge Facebounding edge
Restore the underlying curve Standalone edge
Remove the vertex Vertex of a standalone edge

This task shows you how to:

Untrim an Object

You can restore the underlying geometry.

Before you begin: Open a 3D Shape containing a face.
  1. Select a trimmed or faced object.
  2. From the Surfacing section of the action bar, click Uncut or Uncut (modifying) .
  3. Click OK.
    The face is untrimmed and the input object is set to Hide in the tree.

Remove Parts of the Trim Boundary

You can remove (parts of) the boundary of a cut object.

Before you begin: Open a 3D Shape containing a face.
  1. Select a face boundary created by a cut operation.


  2. From the Surfacing section of the action bar, click Uncut or Uncut (modifying) .
    The boundary is removed.

Remove All Trim Boundaries in One Step

You can remove the boundaries of a cut object all at once.

Before you begin: Open a 3D Shape containing a face with multiple trim boundaries.
  1. From the Surfacing section of the action bar, click Uncut or Uncut (modifying) .
  2. Select the trim boundaries and Alt + right-click.
    All boundaries are removed.
  3. Click OK.
