1st Angle versus 3rd Angle projection

For cross-CAD, learning, and maybe a little friendly competition.

You would think that when it comes to 5 or 6 digits before the decimal they would switch over from mm to M, but that's not the case, (15000mm is represented as 15000mm and not 15M). I guess it is to keep uniformity (one UOM) throughout.

I would think one would change it as well, but not changing it to meters is not really the metric systems fault. To my knowledge there are no ISO standards that say "You have to show everything in mm".

Even if I were doing something like this in inches at some point you convert it to feet unless it's a couple really big dimension on an over all system that is much smaller. You're not going to design something that is a mi square in inches.

I read that as "15 Kittens per MM"... (too early,.. adding one more uom of coffee) :D
