This video shows the process for adding an associative master model drawing to your Product Template. When you use the NX Reuse Library to copy your Product Template as a new design, this helps NX create not only copy of the design part, but also create a copy of the drawing and keep the two copies associative to each other. This works for both the "Copy as New Design" and the "Add Copy to Assembly" actions. As always, copies from Product Templates are editable and can be used to evolve your designs (and associated drawings) over time. Enjoy!
