Useful Tips

  • In the above example, the original object being subdivided is deleted upon creation of the new subdivided surface. To keep the original object in addition to the newly created subdivided surface, uncheck the Delete Original Object checkbox in the Surface Subdivision dialogue box.
  • If you do decide to keep both the original and new subdivided objects, you may want to create a new zone and relocate the subdivisions to this zone, in order to have more control over how the subdivisions are displayed. To do this, first create a new zone in the Zone Management panel. Then select the subdivided surface in the model, and then right-click on the newly-created zone. From the context menu that appears, select the Move Objects To option.
