I recently had the requirement to produce a drawing of a circlip, showing both the working and free view dimensions.
The part was created as an ipart, but in the drawing I was unable to overlay the "free" view over the "working" view, Instead I had to place the one view (free position), then create a sketch of the circlip in it’s working position.
It would have been helpful if I was able to place both ipart views accurately on top of each other using constraints, and then make one of them a dashed line....simple!
