Cut a Surface Using OmniCut

You can cut an object at a segment boundary using one of the cutting commands.

Before you begin: Open a 3D Shape containing a segmented surface.
  1. From the Surfacing section of the action bar, click OmniCut or OmniCutModify .

    You can also Alt + middle-click to access OmniCutModify.

    The OmniCut panel opens.
  2. Switch to the subobject mode by Ctrl + Alt + click or by in the Sculpt panel.
  3. Click the OmniCut panel.
  4. Select a segment line.


  5. Select the Cut Type.

    When you cut a curve at a segment boundary, the appropriate Cut Result option depending on the pick position is specified.

  6. Click OK.
    The surface is cut at the segment boundary.

In the OmniCut case, the input objects that were cut are set to Hide. In the OmniCutModify case, the input geometry is modified and remains in the Show mode.

Note: If you delete the OmniCut feature, the hidden input objects are not automatically set to Show. It must be done manually.

Cut a Curve Using Modify Curve Segment

You can cut an object at a segment boundary using the Trim option of the Segments Modeling panel.

Note: This option creates a datum element.
