CAD for simple 3-D metal & wood projects?

Weather is usally single digit precision. Usually.

For my circuit board layouts granularity was the snap-to grid spacing, usually 0.010" or 0.0125" which are 1/100 or 1/80 of an inch.

The resolution was usually 0.002", the size step between track widths and pad diameters.

The accuracy of the CAD data was 1 micron.

The tolerance was defined as how much larger a pad must be than the hole drilled through it, to ensure that the drilled hole didn't break through the outer circumference. IOW it was the allowable misregistration between the etched copper circuit and the drill machine. It was a manufacturing constraint, not a designer's choice.

LOL Actually spent a good part of my yoot as a horseshoer, doing hand forged, corrective shoeing.

Damned hard to 'dimension' a part, other than by eye, that's cherry red. Amazing how accurate some blacksmith's "eye" can get, though. :)

Woodworkers call it, measure twice, cut once, pound to fit.

For you Commonwealth folks...refer to #10

The measurements may be, but climatologists know the rate of global warming to a tenth of a degree.

Makes for much more sensationalism when graphing and discussing rates of change, akin to measuring crude oil spills in gallons, instead of the standard unit of barrels.

NOT that kind of joint! ;~)

Ahhhh, learning to build with expensive wood. Buy a beautiful piece of walnut, bring it home and mill it to thickness, straighten one edge then the other, and cut to length. Oppps, 1/16" too short, cut it again, still too short. Redraw the plans slightly smaller, start over.... Eventually it is built and you sand the beautiful surfaces through 3 grits and it is finally ready for the finish. Open the can and roll the paint on!

Well, if you're going to give someone the shaft, you might as well do it right. ;-)

I know you did. And it scared all your neighbors away!. :)

ROTFLMAO!

No kidding I just read, and it has to be true cuz i read it on the internet, that scientist have decided that we in north America and in Europe we are headed doe a mini ice age. Apparently the SUN, that's right THE SUN has been causing the earth to get warm! Well apparently the sun has been falling down on the jolately, maybe the people working for Al Gore gave up. The sun has had much fewer than expected sun spots and as a result we are going to experience colder weather. I always called the global warming thing summer.

Anyway how are we going to be able to afford changing things here on earth so that the sun is not affected, which in turn keeps us from turning into an ice cube???

Bzzzzt ... Gotta be teacups, or the granularity is off. LOL

Traceable to NIT?

I've built a couple of airplanes that way.

We call it steel tube blacksmithing...

Sorry. Old news.

Ol' Sol caught up with the curve last week.

Yeah well, I didn't like them anyway... :)

Indeed. How is the government going to justify raising taxes because of global COOLING?

Fire the astronomers. They're ruining the scam!

Same folks that are running obamacare.
