Monty, great stuff! Looks as if you have put a lot of time into this.
What would the tolerance be approximatly? +/- .xxx?
...Chrissi

OK Chrissi since you now how to convert it to a 3D drawing please
plot it to a gif file on hard disk from ACAD and attach it to a message
for us so we all can see it.

Tolerances are about +/- 0.1 on the profiles. All in block form though, no
fillets, rounds etc. I took some graph paper, traced the housings, entered
the points, and extruded the housings. It took the better part of an
afternoon. Tracing and entering took the majority of the time. Good for 3d
mock up, engine mount visualization etc. Please, don't try to do detail
design of a redrive plate from it. You might check the drive shaft location,
I threw that in for ref.; didn't get to the detail part of that yet ;-).

If you are serious about the 3D thing, check out  http://www.rhino3d.com/
faster,better,cheaper, than Acad, plus very compatible with it, and
everything else (if you simply must have drawings). If you know Acad,
learning curve will be minimum, in fact, you will wonder why everything was
so hard in Acad!

Here is a more detailed model with surfs for AutoCad 2000:

You have got to be kidding Monty. That file was well over 5.8  meg.
You forget. Not all of us have DSL. Even zipped it was 500K

Send your request for this file directly to Monty.
Monty Roberts  <montyr2157@alltel.net>
I'll send you the zip file Monty.

Please do a gif or jpg for us. Many don't have CAD of any kind.
