#### Using the Change Manager

PC-DMIS Planner provides you with the ability to manage changes to CAD model files and update dependent inspection plans by using the Change Management dialog box.

To access this dialog box, select File | Operations | Change Manager...

Change Management dialog box

The Change Management dialog box lets you update geometry features in your inspection plans when the underlying CAD model has changed. Planner searches for all of the geometry features in your inspection plans, comparing them against the current CAD model.

- If Planner finds that feature on the CAD model (for example, for a cylinder feature, if there is a cylinder of the correct size, shape, and location in the model), it leaves that feature alone and does not put it in the dialog box.

- If Planner cannot find that feature on the CAD model, it then checks nearby geometry on the CAD model.

- If Planner finds a match in the geometry within the tolerance zones, it puts the original feature in the Existing plan (program) list and the new feature in the New Plan list. In this list you can see all of the values of the features if Display Only Changed Parameters is cleared or, if it is marked, you can see only the values that differ from one list to the other. For any matched items, you can choose to do the following:

- Update - Updates that feature with the new values when you click the OK button.

- Ignore - Removes the matched features from the lists but will not update the existing feature in the plan.

- Undo - Undoes the last action for the Update candidates area.

- If Planner fails to find a match in the geometry for the existing feature, it will put that feature into the Deletion candidates list. For items in this list, you can choose to do the following:

- Edit - This allows you to freely edit the feature, just as if you had double-clicked on the feature in Plan list of Planner's main interface.

- Delete - Deletes the feature from any inspection plans.

- Ignore - Removes the feature from the dialog box but will not delete it from the plan.

- Undo - Undoes the last action for the Deletion candidates area.
