Hugo,
Thanks for your reply,
Actually for me the purpose of using skeletons is quite clear: Im constantly tweaking and building up my design, and the fact that all parts upgrade and still fit automatically is just great and saves me a lot of work.
So Im happy with the concept but confused about the options in Creo..
Im confused why "merge" doesnt work with sheetmetal and should I use "copy geometry" instead? Should I only use publish geometry or is it okay to use merge and copy geometry both?
