SketchUp actually has the same internal precision as AutoCad, 1/1000th

Look it up ...


1/1000th inch? Is that all???

LOL

Good enough for AutoCAD, and certainly well within the specifications of
the OP's original request.

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

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.

Depends on your application. I agree that .0001" is more than enough for
woodworking, but I can easily imagine machining applications where it's
not enough. When I took introduction to milling and metal lathe classes,
we were expected to machine something to within .0001" even as beginners.

1 /10000 as beginners?
Ridiculous. that's an experienced machinist, not a beginner.
Possible yes, practical.. not at all.

Actually..it is quite possible for beginners to do on manual machines
(CNC..easy as pushing the green button)

Will they be doing this on their own in the first 10 minutes in front
of a machine?

No. But with a mentor..they can be doing it in an hour. Teaching
them to read the mike is a hell of a lot harder to do.
