The iCopy Author prepares an assembly for the iCopy command. To use an assembly as an iCopy template, the assembly must contain a skeleton part that drives the other parts in the assembly. The skeleton part must contain an adaptive sketch. You select points in the sketch to use as the control points for placing the iCopy. The parameters in the skeleton part can be added to the iCopy template. These parameters give greater control over the size and shape of the assembly and its components.
