I was singing the praises of F360 when we finaly got design linking. Then I saw this, and said, "Now what is the point in design linking if you can do it between projects!?" I'm trying to design a steel rule die that is common for two or more projects. A design task that is not uncommon. I want to be able to easilly update it when one of the other projects change. I suspect that implementing this may be a tricky thing to do, but it is a vital feature.
