I have found that customizing the standard parts library is baffling, incredibly user-unfriendly and not worth the effort for me.
In the following thread the incredible @Imics shares his knowledge. Maybe this will contribute to your effort.
BTW I wonder where Imics has been?
Please let us know how it goes.
Edit: what is "the big SMAP tool"?
All of the effort I put into the standard parts library was undone completely when I updated to ST9. Now I'm back at square one and was unable to get anything to work at all on the fastener system. It is too much effort when you start over when the software updates.
@nominus38, I like the library as a source but not that crazy about it as an application. If I was starting or a place where I worked was starting out I would probably advocate "saving out" needed models from the database, renaming them with practical and simple names, and putting them in user defined folder(s) from which to place them in assemblies.
I agree, especially with the naming. But the fastener system, if it worked easily and you had a full library of aptly named parts, would be awesome. I loved using it, it's just that it wasn't properly named with things I could use in my parts list.
'SMAP' is from a comapny called CAD-Partner. They provide various addons for SE but one being a standard parts library (actually they provide the one that comes with SE I believe).
