### Active Alignment List

During alignment creation or anytime you wish to view or edit an alignment, this list box displays the various components making up the current alignment, such as the alignment's ID, any recall alignments used, the type of alignment, and the features used by the alignment's axes to perform its rotation and translation.

Editing an Alignment

While you can edit any alignment already created inside the Summary or Command modes of the Edit window, you can also edit an existing alignment by clicking on an element in this list and making the needed change. Once you select an item, the appropriate area of the Alignment Utilities dialog box becomes available to edit. After making your change, click OK to modify the alignment.

For example, if you wanted to modify the feature to which the alignment was leveled, you would select the "leveled to" line from the list. As shown in the following figure, PC-DMIS would display the current feature used for the leveling portion of the alignment, and then it would make the Level button and list of axes available.

Example of the Active Alignment list used to edit an existing alignment

Simply select the new feature, and axis, click Level, and PC-DMIS updates the Active Alignment list to reflect your change. Then click OK to save the change.
