Previously when creating a mould tool I did not link it to the related part. I would like the cavity/core to update whenever i change the part.  I'm now using Mold Tools and trying to fugure out what the best way to link the tool(e.g. cavity/core insert) and part is. Is there a good method that anyone uses?...I though maybe start by making a linked/referenced copy of the part and then using the copy for tool split etc etc. I would ideally like the tool assembly and its parts (except the cavity/core insert parts) to be totally seperate from the product parts when i check them into PDM.

Any ideas? Thanks!
