I too highly recommend that your team does the CAD from scratch. Use a few pictures as reference, but do your own design. Knowing every nut, bolt, washer, sprocket, chain, and spec of dust you put into your drawing will make it that much easier to come up with design improvements. If your team is new to CAD, I would recommend doing the tutorials first, then doing a simple aluminum frame. Then from there you can experiement.
As always, many of the FIRST motors, transmissions, pneumatics (etc) are already available at www.firstcadlibrary.com |
Wow, I feel honored to be mentioned...
But anyway, sharing CAD is a tough issue. I normally don't share it unless it's someone I trust, but even then I put in a "security" measure in order to make sure they're doing their homework. Some dimensions will have been slightly changed, not enough for aesthetics, but enough that any attempt to make the part will fail miserably, or will be hell for the machinist.
As for designing your own, I can send you some renders, as well as answer any questions you've got. Please feel free to AIM me any time, or PM me with any questions. Oh, and that old CAD gallery is WAY out of date.... I ought to link the
new one...
