odd plan scale
odd plan scale
(OP)
Most of the plans I see now are on 11x17 sized paper, occasionally, but more and more, I am seeing plans at nonstandard "engineering" scales.
It seems like it would be convenient if I had a ruler that had 1:8 and 1:16. Does such a scale exist?...If so where can I purchase it?
1) I know an architect's rule works for the 1:8 case.
2) A standard ruler or architect's scale does not work well for the 1:16 case, because the major divisions (and count) occur every sixteenth rather than every tenth.
Just an odd observation...

RE: odd plan scale
Most CAD programs allow you to draw in "real" life dimensions and then scale when you print.
My beef are those drawings that have few if any dimensions on them. When I complain, the arch or designer just says scale them.
Well after you PDF them, copy them and someone else makes a PDF of the copy, and THEN e-mails it - guess what happens - the scale is out the window.
Too many drafters are just TOO lazy to include proper dimensioning. I have seen drawings from the 1880's and 1890's that were works of art and could still be easily constructed today!!
RE: odd plan scale
And I agree with you, I am seeing this more and more. Many civil engineering curriculums do not include a technical drafting/drawing class anymore. Instead, students learn how to use CAD, but they don't learn how to draft. Next thing you know, the drawing won't fit if it's 1"=10' and it's too small if it's 1":20', so, tada! 1:16.
I love looking at old drawings. Drafting was an art back then. Now it seems like an afterthought.
RE: odd plan scale
EVERY drawing, in my view, should have both a reasonable (engineering or architect (less so)) scale noted - both horizontal and vertical not uniform, dimensions must be given so no one has to "guess" what a dimension is and should have a bar scale included (in case of going from A-1 to A-3 or A-4 or just the errors introduced with photocopying, etc).
RE: odd plan scale
Both drawings were, surprisingly, produced by (different) architects...
RE: odd plan scale
I often include a 'scale bar' with drawings and if these are reduced, the scale bar is reduced also... I also include a note to the effect that drawings should not be scaled...

RE: odd plan scale
1:16 is the same thing as 1 in = 16 in.
For the former, use the 40 scale and multiply by 4 (strip a zero) or carry the drawing over to the copy machine and reduce by 16/20ths (80 percent) and you'll have the 20 scale.
f-d
p.s., I know nothing about CADD other than I know you can set the scale to whatever you need.

RE: odd plan scale
We mostly work in 1:10 and 1:20. But in the past at other jobs I have worked in 1:500 on pretty large subdivisions. 10 sheet drawings at 48"x60" at some decent to see scale.
In the end 1:16 doesn't make sense to me. Anything not on a standard scale seems a bit off. I guess I am old enough to know how to hand draft, but young enough to watch CAD go from r14 to the current icon setup.

If possible, get the drawing in CAD and work from the .dwg file.
In addition to the problem of working from copies of copies, there is something else to be watchful of:
When a drawing is faxed, some fax machines will add a narrow strip at the top or bottom of the page which shows the transmission details. In order to make room for this strip, it compresses the image top-to-bottom.
This distorts the faxed drawing. Squares become rectangles, circles become ovals, and angles can change.
