To constrain the position of the clipping planes manually in a 3D workspace

1. Click Home tab Project panel File Options .
2. In the File Options dialog box, click the Culling tab.
3. Select Constrained for the Near clipping plane, and enter the desired value in the Distance box.
4. Select Constrained for the Far clipping plane, and enter the desired value in the Distance box.

   Autodesk Navisworks uses the provided values unless doing so affects the system performance (for example, makes the whole model invisible), in which case it adjusts the position of the clipping planes as necessary.
