autocad 2011 problem with misure e scale

[B.Movie]

Hello everyone!
I'm a novice in using this software and I have a problem that's blocking my job advance. I use the version for students of autocad 2011.
they taught me that autocad does not reason in meters, centimeters, millimeters, etc. but with its own internal unit, and that therefore I can insert using the unit that I find more congenial, then to scale you think in the printing phase.

now, so I did: design a plant by setting the actual measurements, for example a wall of 9,3 (m). But if I move on layout, I create a new window and imposed the 1:100 scale, the design is very small, which makes me think that autocad sees that 9.3 as millimeters. Is there a way to show the software that value as meters, eliminating all the problems I have in print?

Please help me!

...is there a way to show the software that value as meters, eliminating all the problems I have in the printing phase? . . .

I recommend you first to see some tutorials on the layouts.
you just have to give each window the scale you want, simplifying, if you select the window and go into its properties, in the custom scale enter the value 10 and you will have your scale 1:100. then there are other methods, but in the meantime see this.

Try to see if this helps you:

Thank you, it seems that it works, I'll make a print test! in case I have to make other scales what is the proportion to be applied? like 1:50?

Let's make it simple, b movie, sum up what happens inside autocad.

You already realized that the auto unit is something apart from the final press units, and we're already at a good point.

The next point is the print scale. in the print window there is a value to be inserted and that's mm printed / unit' autocad.

as you drew, the correct scale to get a 1:100 print is 10:1 (10mm=1cm / 1 unit' autocad).
Why? Soon said. you have designed 1 meter real = 1 unit, that real meter if you print 1:100 will have to be printed 10mm, so 1 unit' autocad will have to be printed 10mm (see report 10:1).
you cheated on a scale very easy to use mentally.
What happens in the layout? It happens that you can see the model, enlarging/reflecting as much as you want.
when you do a 1:100 window you told autocad that you want to see the size of the model a hundredth of how they are drawn in the model.
in practice (returning to the print scale) if from the model you had 1m=1u and 1u=10mm on paper, now you have 1m=1u (model) 1m=0,01u (card) and then leave the fixed print ratio at 10mm=1u you will have a print 100 times smaller (so 1:10000 no more 1:100).

at this point the routes are 2:
or multiply the print factor (then 10:1 passes to 1000:1) and leave window 1:100
or set the window 1:1 and leave the print factor 10:1 (which I recommend).

What does that mean? that you will have to reason on the scale of the layout windows.
drawings in the model with what we call improperly 1:100,
if you want to print 1:50, just change the paper window scale in 2:1 (1:100 x 2 = 1:50)
if you want to print 1:20, just change the paper window scale in 5:1 (1:100 x 5 = 1:20)
if you want to print 1:200, just change the window scale in paper in 1:2 (1:100 x 0.5 = 1:200)

and so on.

The relationship you always have to keep in mind is
m real / unit' autocad*print scale (mm/u)
if you also insert paper space the ratio becomes real m / unit' autocad x scale window paper x print scale (mm/u)

like 1:50?

1000 mm paper = 50 units

thank you so much to all for the help, you were very kind!

I would have one last question: would you recommend me a good guide (also paper) for autocad 2011?

Bah... I am always of the idea that autocad uses the millimeter as a unit. Who knows why if 1:1 scale mold and I used the millimeters there are always 10 mm on the a4 sheet... to each of his theories :biggrin:

try to convince a geometer or engineer to draw civil works in millimeters:biggrin:

This is another problem... in fact there will always be the distinction between the categories of those who use the meter and those who use the millimeter, from the basis of reasoning.

I know. It's almost impossible.

Well, that's true. as it is true that "try to convince a mechanic to draw 1:100" :biggrin:

to each of his units, for needs, more than for comfort.

Imagine an electronic that draws the circuits of a chip.... in meters?
or a transporter, who draws a highway exit ... in mm?

I think this application http://www.cad3d.it/forum1/attachment.php?attachmentid=16361&d=1282818497 that simplifies the use of "layouts" by facilitating the layout in the "Layout cards" for the final print, can be useful.
Once you choose the adopted measurement unit and scale to print, the scaling operations of the windows in the layout are made by the program.

inside the zip there is a short guide in mht format (internet explorer) that can also be recalled by toolbar or application.

Excuse me, as I have this problem with the stairs, explain how to use the downloaded program?

Thank you!

Okay, I solved by reading on the net. I just have a curiosity if you can.

when I design in cm in the model space and then create the view in lay, for example on a3, I do not understand why it puts the type 2:1 scale. better to say: if I know that in reality that representation corresponds to a 1:100 scale, how can I show in fact 1:100?

I actually got around the obstacle. Before impaginare in fact I modify the properties of the model passing to meters, but I do not think it is the right thing to do.
