Today I was looking at a neighbors' house location and it is drawn at 1"=70'. Out of curiosity, I looked at the website of the company which drew the location, and they have sample drawings on line. One of them is 1"=35'.
Of the companies I have worked for, we all drew things at scales such as 1"=10', 20', 30', something which could be easily scaled with an engineer's scale.
What scales do people here draw at?
All over the place, from 1"= 5' to 1" = 100', depending upon client needs, parcel size, sheet requirements, etc., etc.
.
But 70 and 35 are odd ones, for sure.
I do almost everything at 20 scale, but I mostly survey small lots with fine detail. I sometime use 30 scale if it's a simple house and it will save me a paper size. I dislike cluttered drawings as much as drawings with a lot of white space. I've gone from 10 to 100 scale, depending on what works best. To me, it's the appearance and "neatness" of the drawing and being about to display the information clearly.

Back in the late 60's my Dad had a scale that looked very similar to a Tri-scale, with an exception. It had a fourth tine. I would guess it would be called a Quad-scale. It also had a 1"=70' and a 1"= 80' scale on it. I have never seen another one in over 40 years.
Personally I have a set of flat scales that have the normal scales of a Tri-scale and two more. They are 80 and 100. You need a magnifying glass for them.
When hand drafting we used a scale we could measure directly from an engineers scale. Sometimes it was not the best choice so there were a lot of blown up details. Today using computers any reasonable scale would be improper as long as it presented the data clearly. More important than the scale used is having a good usable scale bar on every drawing. With the ease of blowing up, shrinking and what some consider odd scales, that usable scale bar becomes very important.

I use the common scales 10, 20, 25, 30, 40, 50, 60, 100, 200, 300, etc...
I use what will fit best on 8.5" x 11" or 11" x 17" media.
I use whatever fits nicely for my client and recording, but I NEVER use anything ends with a 5 other than 25... I just don't have a scale for it. I know in this day and age it really doesn't matter, but I'd like to think that I have the common sense and mentoring that taught me that.

When hand drafting sometimes we would use a scale like an 1"=80' and use the 40 scale to do the measuring, easy conversion and it filled the large gap between the 60 and 100 scales.

10, 20, 30(not common), 40, 50, 60, 80(not common), 100, 200.

I'm assuming that you mean "not common" in your area. Because 30 is very, very common here for house locations/mortgage surveys/lot surveys (you know what I mean). But if a 30 won't fit these days because of all the text, I'll just jump to a 40... it's not that much of a difference.
Correct, I was refering our office mapping 'statistics'..your mileage may vary.
Once upon a time I worked as a Map Draftsman. When plotting "post plots" of locations of offshore seismic shot points (locations of seismic explosions), the coordinate systems were often families of hyperbolic lattices. The tools we'd sometimes use, if available, were Gerber Variable Scales. Essentially it was a spring enclosed in an aluminum bar with a plexiglas cover, and we would "stretch" or "compress" the scale so that it would divide the distance between two hyperbolas into 100 equal parts. The instrument was about 10-12 inches long & EXPENSIVE.
Gerber Variable Scales - long, long ago.
I once used the standard scales. That was during the hand drawing phase.
Since cad drawings are in and fitting paper space is important, I use most any scale will place a scale bar.
I love when some lawyer or realtor calls and can't figure out a cutoff problem himself and draw the line on some copy.
The fax copies that get circulated around from bank to realtor to lawyer certainly are not to the scale the drawing reflects.
I have not used a 1"=66' yet, but it has been tempting.
I like using the scales that can be scaled with an engineer's scale. In this day and age, I still think it matters. There are times I have used an odd scale because I absolutely "had" to. But most the time I will find a practical scale. (10, 20, 30, 40, 50, 60)
A 35 or 70 scale makes it almost not matter at all....just make it fit the paper, and provide a bar-scale to give someone a sense of size since they can't lay a scale down on it anyway. (I guess someone could measure decimal-inches and calculate a distance out but why not make it easier for them)
1"=40chs.
40 scale will give you chains directly and a township fits on an 18"x24" sheet nicely.
I've never tried to get one through the County though;-)

We always try to stick to the standard scales, e.g. 10, 20, 30, 40, 50, 60, 100, 200, etc.
We'll sometimes use scales that can be measured by either doubling or halving one of those standard scales, which gives us things like 5, 15, 25, 80, and 120. But the only time we'd ever use a scale like 35 or 70 is when the overall picture is by far the most important thing, and the drawing could just as easily be labeled "Not To Scale".
Most local agencies require standard scales, and won't even accept things like 1" = 25' or 1" = 80'.
I've got a Gerber Variable Scale on my bookshelf right now. I use it now and then when I get a reduced or enlarged plan that doesn't fit any known scale. Nobody else in the office seems to be as impressed with it as I am. I don't have any idea what all the little numbers mean down by the slide bar. It's like some kind of Martian slide-rule I think.
I stick to the standard scale increments. For reduced plots, I often see a scale bar with no text other than "one inch at full scale" or something like that. It's up to you to figure those out.

That's called a bastard scale.
If it ain't on the tri scale, or a multiple of 10 of what's on the tri scale, I don't use it.
I worked for a forestry company back starting out that used 1" = 1 chain; 1"=2 chain.. up to 1" = 10 chain, I think I still have one of those scales lying aroung somewhere. Now it is the standard engineers scale up to 1"=500' what ever will fit on a 18"x24" sheet.
Just like Tommy Young said. If it's not on a tri-scale or a multiple of it, it's not coming out of here.
