Relative Location (%) Slider
Select the desired percentage of the location distance between the two coordinate references, with the distance being calculated from Coordinate Reference 1 to Coordinate Reference 2. Therefore, if Coordinate Reference 1 = (50,-100,0) and Coordinate Reference 2 = (150,100,-20) and you choose 75% as the relative location, your template-based product locates the entity at (125,50,-15).
