#### Adding and Using Control Points

1. Access the Scan dialog box.

2. Define your scan. Based on your type of scan, the minimum number of boundary points for the following scan types are automatically defined:
   Plane
   Sphere
   Cone
   Cylinder

3. Click the Control Points tab.

4. Add interrupt point locations by one of three available methods:

- Method 1: Key-in point locations. Click the Add button and then type the required values for each point.

- Method 2: Select the From Manual Hit check box and then use the machine to touch the locations on the part where you want to have the control points. PC-DMIS adds the information to the Control Points dialog box.

- Method 3: In the Graphics Display window, left mouse click on the CAD model where you want to have the control points. PC-DMIS adds the information to the Control Points dialog box.

For methods two and three, PC-DMIS automatically snaps the chosen points to the cut plane of the scan for all scan types except Patch scans.

5. Continue using the methods in step 4 to define all desired control points.

6. Once your control points are defined, click the Create button. The Scan dialog box will close and create your scan.

7. If you want to edit, delete, or add additional control points, simply click the Control Points tab at any time and make modifications as needed.
