#### Edit Control Point

If a preexisting curve is selected, the dialog box will also contain a list of control points within the Control Point list. Select one of the control points and PC-DMIS will place the corresponding values in the X, Y, and Z boxes so that they can be edited.

To edit these control points:

1. Make sure a curve feature already exists.

2. Open the Edit window.

3. Select the curve in the Edit window.

4. Press F9 to activate the Curve dialog box.

5. Select the control point to be changed in the Control Point list.

6. Edit the individual X, Y, Z components of the point.

7. Click the OK button.

The curve will then be updated to reflect the changes.

Note: If the control points on a dependent curve are edited, it automatically becomes an independent curve because it is no longer based on the input set.
