### Additional Level Manipulations

PC-DMIS allows you to perform these additional level manipulations using the View Setup dialog box:

- Create a new level. See "Creating Levels".

- Delete an existing level. See "Deleting Levels".

- Modify an existing level. See "Modifying Levels".

Level additions and modifications require the selection of CAD. You can restrict selection to different types of geometry in the same way as selection is restricted in the Edit CAD and Delete CAD dialogs. Selection can also be restricted to an existing level that is selected.

See "Displaying, Creating, and Manipulating Levels" in the "Editing the CAD Display" section for detailed information on how levels are used with the View Setup dialog box.

You can also create levels using the Make CAD 3D menu option. See "Making CAD 3D".
