Select an entry in this list to specify the alignment relative to which the measurements in this item are to be made. For example, to measure the points relative to PLP Alignment 1, select PLP Alignment 1.
If you want to specify the alignment during the inspection, select <Active Alignment>. You can then change the alignment using the Active Alignment list in the Measure tab > Current panel.
If you want to change the alignment for this item, select a new entry in the list. PowerInspect automatically recalculates the measurements relative to the new alignment.
