## Working with CAD GD&T Callouts

PC-DMIS lets you display CAD GD&T callouts that are part of your CAD model in the Graphics Display window:

Sample CAD GD&T Callouts Displayed in the Graphics Display window

Note: These callouts are not the same as PC-DMIS's GD&T FCF dimensions. These CAD callouts are stored directly in your CAD model and are simply CAD elements. They do not initially perform any function inside of PC-DMIS other than providing visual information in the Graphics Display window. However, you do have the ability to import them as GD&T FCF dimensions into your part program. See the process detailing importing these below.

Showing the CAD GD&T Callouts

The ShowCadGDT registry entry, located in the Option section of the PC-DMIS Settings Editor, controls whether or not these callouts are displayed by PC-DMIS. If this value is set to "FALSE" then PC-DMIS will not display the callouts, and the entire GD&T callouts area of the Rotate Options dialog box will be disabled. The default value is "FALSE".

You can also show these callouts by enabling the Toggle GD&T Items icon .

Moving the CAD GD&T Callouts

To reposition a CAD GD&T callout, place PC-DMIS into Text Box mode , and then click and drag the callout to a new location.

Filtering the CAD GD&T Callouts

Enter Text Box mode , right-click on a GD&T callout, and select Cad GD&T Display Filter from the short-cut menu. The Cad GD&T Display Filter dialog box will appear, showing a list of CAD GD&T information and two columns of option buttons (Show all and Hide all) to toggle the visibility state of the various GD&T callout elements.

Selecting an option button will either show or hide that item immediately. Clicking OK will close the dialog box, storing the current filtered state until accessed and modified later.

Showing or Hiding Individual Callouts

Enter Text Box mode , right-click on a GD&T callout, and select one of the show or hide menu items.

Importing Callouts into your Part Program

PC-DMIS can import selected GD&T callouts as dynamically-generated FCF dimensions or datum definitions.

1. Ensure that the GD&T callouts are visible by enabling the Toggle GD&T Items icon .

2. Enable GD&T Selection mode from the Graphics Modes toolbar.

3. Click on either a single GD&T callout or box-select multiple callouts.

- If you click on a single item, the GD&T dialog box appears
  , allowing you to adjust options. PC-DMIS also generates in the Edit window all the commands needed to create the specific datum definition or FCF dimension in the part program. If you click Cancel, PC-DMIS removes the newly added commands. Clicking OK closes the GD&T dialog box, retaining any commands imported into the part program.

- If you box-select multiple callouts, the GD&T Selection dialog box appears
  , listing all the selected items. PC-DMIS draws any box-selected items in red. You can then click on individual items from this dialog box and it will turn yellow. You can then use the Add button to import the single item you selected, or you can use Add All to add everything in the dialog box into the part program. Once items are added, they turn a gray color. Clicking Cancel closes the dialog box.
