length measurement unit

[tatyb295]

Hello everyone... I had to ask a question maybe too trivial, but for me important.
I have a design on autocad in which there is written as design scale title 1:50.
and here everything ok, because I understand that the real lengths in meters were divided for 50.
the problem is that I noticed that the lengths of the design correspond to those of reality, for example a beam was designed with a length of 1.4 and actually measures 1.4 meters.
My doubt is if they were wrong to write the ladder or if it's me who didn't understand anything about autocad measuring units!
How do you see that 1.4 program?as meters?

the units of measurement do not fit, they always draw in scale 1:1.
you just have to decide (without setting anything) to what the autocad units match.
so if a beam in reality measures 1.4 meters, you can draw it of 1.4 units (if you decide that your unit is the meter) or 140 (if you decide for the centimeters) or 1400....
in the printing phase you will only have to set the right values of mm=unit in relation to the plotting scale.

Thank you very much!!! really nice! Now it's all much clearer!

only one thing... if then a flender moment measures in reality 82 kn and I represent it with 0,82 units I have to write that I used a scale of 1:100 moments, right?

depends on the printed result, you have to write the scale in which (poi) molds actually.
For example, the same design can print it roughly half or twice, even in relation to the sheet size.
make a print in the format you need, measure and see if the scale you indicated corresponds.

If therefore a flender moment measures in reality 82 kn and I represent it with 0,82 units I have to write that I used a scale of 1:100 moments right?

No, sorry for a second. Things don't fit. kn is not a linear measure (which among other things is not even the unit of measurement of moments), which is correct to write to us next to "scale 1:100"? rather draws a graphic scale of reference. . .

He's obviously doing a chart of the moment.
ascissa= length, ordered = force
