Re: [CAD_CAM_EDM_DRO] CAD Questions

Try Bobcad V18. It does what you are trying to do and it is a true 3D cadcam software. If you buy it get the training CD's. It's easy to use but without the CD's its a much larger learning curve. Its glitchy but, its still the best cad/cam software for the money that I've seen. If you operate it exactly as it was designed to be used it works pretty well. It's just not very forgiving in the area of deviating from the intended process. Everything matters I've noticed and the training CD's show exactly how each operation is done. They will barter on price for a package example: I bought V18 with training CD's,manual, 3 seats and 45 days free support for $400. Probably get it even cheaper now. They offer no free support or updates. V19 is just a different face with some V18 fixes and improved file imports. V18 covers all aspects of machining. I use it everyday and it saves me alot of time.

Gentlemen:

I am not very familiar with CAD. I made a shape with a series of
lines and arc segments (36 total)using TurboCad (Ver 6) and
DeltaCad. To handle the cutter comp, it took me maybe 30 minutes
with DeltaCad and the finished product seemed OK. With TurboCad, I
couldn't get the offset correct on arcs, but spent a lot more time.
My questions are:

1.Does one have to offset *each* segment, then add the corner radii
in order to generate the compensated shape, or should the CAD do it
more or less automatically once the direction and starting point are
set?

2. Once the basic shape is completed, how long should it take to
generate the compensated shape?

3. I haven't yet tried the Ace Conveter; how should one set start and
direction of cut?

4. Since my applications are just hobby type, are there some low cost
CAD systems which you would recommend?

Thanks in advance,
Jack C.
