CAD for simple 3-D metal & wood projects?

Some of us have to work to .00005" or smaller.

True indeed.

If you can visualize the part you want to make, a pencil is all you need to capture it. The designers of this didn't need no stinkin CAD:

If you can't create it in your head then CAD won't help you. It doesn't recognise your conceptual errors. I've embarrassed a few engineers by pointing out why I couldn't make what they had drawn.

Well even fewer of us work to .0000000000000000000000000000000000005" or smaller but that still does not mean you need a program to do that when .0001 is way more than enough.

Professional version versus free version.

Presentation tools (Layout), dynamic components, and a handful of not really necessary solid modeling tools are not part of the Pro version.

Modeling functionality is otherwise identical.

Yep, that's when you bring out the right tool for the job. But apparently not necessary for the OP.

Obviously not, but with CAD it might not have taken 56 years to build either. ;)

That should be "not part of the FREE version.."

Their problem wasn't just drafting, they didn't know how to combine lateral thrust vectors on the columns.

Cross posted to metalworking.

So yes...

Im posting from rec.crafts.metalworking.

The fact that it was cross-posted into "metalworking" made 50 microinch tolerances required for wood? These metal-heads are amazing!

Thank you... we are! We can do woodworking more precisely than you can, too!

Once again, proving that you're simply amazing (i.e. simple and amazing).

What would the value of the integral over (-infinity, infinity) of

1/(1+x^2) dx look like if you didn't express it as the Greek letter PI???? Even being in error by the amount above would make it that you bought it from Kmart--apologies to Kmart (and/or the Sears Holding Co.).

_I_ can, with woodworking tools. I built period reproductions of French Revival decorative furniture for about 20 years.

Except for a table saw, most of it with hand tools, per the authentic methods. Doing fit-ups to a thousanth is a must if joints were to be perfect. (and yes, I know about the growth of the wood, but some joints demand that precision)

No metal fasteners in them, either. Gauche'.

I can do dovetails you can't see a gap in by hand, too. Can you? I doubt it.
