earlier this year I sent an e-mail to Spears Mfg. requesting any models they could send me. After faxing back a confidentiality agreement they sent me almost all there fittings as IGES files. Because I was setting up SW routing they only helped me for reference.
McMaster-Carr has started to offer SW models as a download option on a few items. Most of the time you will have to settle for a step file but occasionaly you will find an actual SW model available for D/L.
Yep, tried McMaster-Carr as well. Nothing. I was kind of surprised at that. They have models of most standard hardware.
Maybe I've got a buddy that is a plumber. Maybe I'll see if he can get me dimensional info.
A little off topic, but I got some respect from my bud's in the construction trades a few years ago. They had to build some realtively tricky stairs. I modeled them and made detailed prints of stringers, steps and a landing. I pre cut a bunch of wood and simply put it together. They were shocked.
Anyway, if anyone else gets any ideas, let me know.
You may want to try Charlotte. I know they have some 3D data of PVC pipe and pipe fittings. Here's the direct link to the online app (make sure and use Internet Explorer). I found them a while back through Thomasnet. Also, if you're ever looking for Polypropylene fittings, banjocorp.com has a ton.
I recently received from my technical rep from Spears a CD containing a technical information program of all Spears components including fittings, valves, flanges etc. It also contained an application for 2D/3D import of these items into the AutoDesk product, but also seemed to have an solid models in IGES for import. I have yet to fully install the library modules but you may want to look into obtaining it. Not sure how integrated it is setup for SW.
