You can also use it to modify levels, delete levels, and view levels in
the Graphic Display window:A CAD level consists of a group of user-selected CAD geometries or elements selected from the Graphic Display window. The level information is saved with the .CAD file, so that if you import the .CAD into another measurement routine, the level information is available there too.
You can define which levels are displayed in each view of the Graphic Display window by using the CAD Levels dialog box (Edit | Graphic Display Window | CAD Levels). Once levels are defined, you can view the levels using either the CAD Levels dialog box or the View Setup dialog box (Edit | Graphic Display Window | View Setup).

CAD Levels dialog box
The dialog box contains these items:
Levels List
The list of levels in the upper-left area of the dialog box shows all the current levels in the CAD model. The list always contains the default level 0, a level that automatically contains all the CAD elements in the CAD file.
Here are some operations you can perform using the levels list:
Double-click on a level from the list to select all CAD elements assigned to that level.
Select a CAD element in the Graphic Display window, and press and hold Ctrl on the keyboard to select the corresponding level in the level list.
Select the check box next to a level to show the selected level.
Clear the check box to hide the selected level.
Visibility
The Visibility area provides option buttons and icon buttons that allow you to run visibility operations in order to change the hidden state of levels.
The
colored icon at the top of this area shows your current screen layout.
It corresponds with the icon used in the Layout
area of the View Setup dialog box. See "Setting Up the Screen View".
The Blue, Red, Yellow, and Green options limit the visibility operation to only that "view" of the Graphic Display window. The All option applies the visibility operation to all views.
These command buttons have pictures on them that depict their action:
Hide - Hides the level selected
in the list.
Hide Siblings -
Hides all the levels except the level selected in the list.
Show - Shows the level selected
in the list.
Show Siblings -
Shows all the levels except the level selected in the list.
Show All - Shows
all the levels in the list.
These buttons are unavailable for selection until you select a level from the list of levels.
Editing
The Editing area allows you to modify CAD levels. For all buttons except Create, you need to first select a level from the levels list. The buttons affect that selected level.
Create - Creates a new level in the CAD model. Initially, there are not any CAD elements assigned with this new level. You need to use the Add button in the CAD Elements section to add CAD elements selected from the Graphic Display window to the new level.
Rename - Renames the selected level. You can also rename a level by clicking on a selected level in the list until the cursor appears.
Delete - Deletes the selected level. PC-DMIS assigns any CAD elements that were on that level to the default level 0. You cannot delete the default level.
Transform - Transforms the selected level. When you click this button, PC-DMIS displays the CAD Transform dialog box. See "Transforming a CAD Model" for information on using this dialog box.
Color - Changes the color of all CAD elements in the selected level.
Saved Views
The Saved Views area stores the level visibility state in the CAD model. These are saved inside the .CAD file. Use the drop-down combo box to either select and recall a saved view or to specify a name for a new view.
This level visibility state does not include the number of graphics views. The number of graphics views can only be saved using viewsets. See "Working with Viewsets".
Save - Saves the current level visibility state using the name entered in the combo box.
Delete - Deletes the saved view selected in the combo box.
CAD Elements
The CAD Elements area modifies the level of the selected CAD elements. You can select (or deselect) CAD elements by simply clicking on or box-selecting them in the Graphic Display window. Selected elements are highlighted.
Add - Adds the selected CAD elements to the selected level in the list.
Subtract- Removes the selected CAD elements from the selected level in the list. The CAD elements are assigned the default level 0, but only if they are on the selected level. If a selected CAD element is not on the selected level, then that CAD element is not modified.
Deselect All - Clears any selected CAD elements on the Graphic Display window.
Selection Filter - The check boxes in the Selection Filter area filter the type of CAD elements assigned to a CAD level. You can also use the Color check box in this area to filter your selection by the color of the CAD element. When you select the Color check-box, the color of the next CAD element that you select in the Graphic Display window is used as the filter color. For subsequent selections, you can only select CAD elements with that color.
Creating Levels
Access the CAD Levels dialog box.
Click Create from the Editing area. A new level number appears in the list of levels.
Select the new level, and rename it if desired. Even if you rename the level, PC-DMIS still shows the level number in parentheses.
Ensure that the CAD level is selected from the list.
From the Graphic Display window, select the CAD elements you want included in the CAD level. To limit which CAD element types are selectable, select the check boxes of CAD elements in the Selection Filter area.
Click the Add button. PC-DMIS assigns the selected elements to the selected level. Now when you show that level and hide other levels, PC-DMIS shows only those elements.
Click OK when finished to close the dialog box.
Modifying Levels

Select the level from the level list.
To add elements to the level, select the CAD elements from the Graphic Display window, and click Add. PC-DMIS modifies the level accordingly.

Click OK when finished to close the dialog box.
Deleting Levels

Select a level from the level list.
Click Delete. PC-DMIS deletes the level and assigns all CAD elements of that level to the 0 level.
