I have had this issue a couple of times, where I have a drawing created and when I change the original model or move it around, it causes havoc with the drawing. It would be great if as soon as you position an image of a part in a drawing, that image would become fixed in place, both in location and scale, independent of the original model. It would update along with the model and can be manually moved of course, but would just not move around the page or change scale by itself.
Thanks!
