The target assembly is host to the iCopy results and contains the geometry necessary to position the iCopy results. The target assembly geometry needs to correspond to the iCopy template. Thus, it is a good idea to understand what the iCopy template expects as inputs. This image shows the iCopy template and highlights the points that are used by the target assembly geometry.
To place a single iCopy result, you need a work point that corresponds with each point defined in the iCopy template. To place multiple iCopy results, you need a work point for each point in the iCopy definition. You also need a rail to define the path for each work point, a work plane to define the position of the iCopy results, and a path for the pattern.
