I am tasked with creating a parts/fastener library, mainly fasteners. I have toolbox, which I use to create part geometry, but otherwise it seems pretty useless for reasons discussed in thread 559-88584. I don't want a program that inserts a bunch of special code in the part files that will come back to haunt us later (we had this problem with "gold partner" SolidMech about 2 years ago). I know many users have made their own libraries. I would be intersted in purchasing someone's library, but I imagine the chances are slim of us both having the same property names, part numbering scheme, etc. If anyone knows a way to use someone else's part library without renaming a bunch of stuff, or some other solution to creating my own fastener library without too much overhead (I might even be willing to try another software package), I'd really appreciate the info. I think the ideal system for us would be to have one fastener with many configurations, each having a configuration-specific description that links to that specific fastener's length, major diameter, etc. Maybe it would be best to keep it simple and just have, for example, an M8 SHCS part with configurations for each standard length. Any suggestions?
