There was a time that the under 20s can't know... or you downloaded a component like a union fitting and got the entire part family with it. That time is finally over on the sites I know. I tried to download a fitting from Bénéinox and I told myself that with a recognition of function, I shouldn't have to rebuild the family for long. Only when I start the reconnaissance, it can't recognize the " main nut". Do you have a solution? How do you proceed?
And yes, the time for complete family downloads is long gone... (sniff!).
Concerning some available downloads, such as on the " Bene-inox " site (or better the 3D Catalog to download -the equivalent of the DVD for the old-), it is possible to retrieve some components directly in " Solidworks " or " Macro Solidworks " format. This will already be easier than trying to go through Solidworks function recognition (I've never been able to convert anything correctly with it). It's certainly not a panacea but it's better than nothing, but I think it's over for the family of complete pieces.
Specifically concerning Union fittings, I have given up on creating families of parts and my library is full of unique parts (too many different types on this kind of products).
