Engineer's Scale

[Anonymous]

There isn't really a group for this question. Since I am a Cad Manager and
this has come up, I will ask it here. Does anyone know why there is no
1"=80' for Civil Engineer Plans? Every Engineer's Scale is
1"=10,20,30,40,50 & 60. Why is there no 80 scale? The only 2 reason's I
can think of are as follows:
1. The scale is a triangle, so there's no room for an 80 scale.
2. The scale was designed when only full size drawings were used.
We now use half-size plans for everything, and for a 1"=40' scale
(full-size) drawing, you can't have half-size plans. What are everyone's
thoughts on this......


Thanks,

Steve

I believe your point #1 is most likely. As far a Every Engineers scale; I
have one with 10 (twice), 20,25,30,40,50 & 60. It's a flat scale that reads
forwards and back on each edge. I think the second 10 should have bee 100
but they didn't want to graduate it that closely. I've produced 100 & 200
scale plans. 10 & 20 do for those. When for field use I used to have a flat
scale with only 10,20,30 & 40 a 60 scale was twice the 30. I'd have no
problem producing a 1" = 80' plan.

The owner at my part time job submitted a 60 scale to the local planning
board. They rejected it on the grounds that it wasn't a standard scale, by
their circa. 1930 regs. He resubmitted at 1" = 10 Chains (a standard listed
in their regs).

I think the Standard scales on the triangular scale started as common use
and are now traditional.

Have a Happy
Allen

The poor programmer that got tasked with it probably only had an office
supply catalog as a go-by. If they asked everyone what they all needed, we
will still be waiting for R2000.

Make a suggestion at AUGI's website, and if enough people ask for it, it
might just get in.
Is this limitation still there in the more CIVIL specific versions of
AutoCAD? Plain AutoCAD is no longer the defacto all-inclusive version, it is
just a few ticks above LT as a basic core product.

same question as Doug...

Zoom 1/960XP or zoom 1/80XP (arch or eng).
Also .."a few ticks above LT"..????? If you mean the ACIS modeling kernal, full rendering capabilites, muti language programming environment. I wouldnt consider just those three mere ticks. Visit Autodesk's web site there is a page under the AutoCAD LT info page that lists the additional abilities and powers that AutoCAD has.

I'm in civil and there are many times I would love to have an 80 scale. The
jump from 60 to 100 is a large jump when setting up full-size sheets. The
last engineer I worked for had a regular engineer's scale that did have one
side with 80 scale. I believe it replaced the 30 or 40 scale. They're out
there, somewhere.

i dunno why, but when i produce an 80 scale drawing, every engineer that saw
it asks "why the oddball scale"... i would tell them to use the forty scale
and multiply by two, or i can plot it at 60 scale, but it will be double the
sheet count, or the drawing will be too small to read...

The oddest scale I ever saw was 1"=25'..didn't even know that existed much
less was used by anybody.
My State DOT uses it so that when you get a half scale drawing (i.e. 11x17)
you can still use a scale on it.
I saw a engineers scale with that graduation on it the last place I worked.
Found out the guy got it from out of state.

They thought 80 scale was odd.. And what exactly do they do for 1"=100 or
1"=200 etc plans..those don't exist on any ruler that I am aware of...What
they cant multiply by 2 if it not in increments of 5 or 10?
