Well Duh moments

my question is which is funnier, decimal inches or decimal feet?

Decimal feet is standard in civil engineering. Don’t tell me you’ve never seen a surveyors tape with tenths of a foot marks.

Never have. (oh, sorry Greg, you asked me not to tell you that) We got rid of those around the same time that we moved on from the Slide Rule.

For people who have never used foot and inch measurements, it seems totally incomprehensible, illogical, unreadable but very exotic.
For me as a CAD program developer, it is hell to manage these units...
Why do some people still use these units?

As a general rule, for some reason it seems people draw using the measurement system that was used to manufacture the components being depicted.

We all agree that some manufacturers use sensible units, others use an arbitrary and irrational system.

What cracks me up is when I receive a floor plan for a brand new building and the overall dimensions are to some small fraction like 64’-0 3/64”, like that’s going to happen.

When I got my first laser distance measurer I was miffed because it gave me measurements in 1/32s. At first I spent a lot of time rounding numbers to 1/8ths in my head, but then I just gave up - I was wasting time and distracting myself from the task. So now I just write down the 32nds, and I just enter them into PowerCadd now too, because my dimension lines will just do the rounding for me - no extra time or thinking required.

And CM? Just enter the number with cm and PowerCadd will convert it - no need to type in a conversion factor.

Same with survey notations. For the angle just type in the initial of the first compass direction, degrees, minutes, and seconds with a space between the numbers, no units marker needed, and the closing compass initial - and PowerCadd will put the line at the proper angle, page top North. Example n 30 24 12 w.

It’s a beautiful thing.

Counterpoint:

Doing as-built surveys for building construction, it's my practice to disregard any dimensional information smaller than one full inch.

I do enjoy the input luxuries that PowerCADD affords us, just as you do, Greg, it is a tremendous tool.
