Does anybody here know how to use AutoCad? I've been learning from online material and I think I'm getting the hang of it but there's one thing I still can't get right: scale.

I start up a new drawing, set UNITS to use Metres. Draw everything in Model space by the premise that "1" means 1 metre. All looks good and pretty until I move over to Paper space, where it looks TINY. If I set it to 1:1, it seems to take up the space on paper I'd expect it to take if I set it to 1:100 or something. It would seem that what I used as "1" wasn't interpreted as 1m but maybe 1mm or something. Hence the drawing needs to be set to a much larger scale to take up about the space I expected it to take relative to the printable page.

I've looked online but it doesn't seem to be clear ANYWHERE. I've asked people but haven't gotten a straight answer. Does anybody here know how to get it right?

I need to draw buildings, floor plans. This is one of the things I'm supposed to know if I intend to be an Architect

You have import units and drawing units.
Set both to desired unit you wish to use.

I personally use millimeter because meter is too big.

And on another note, 1 meter can not fit on a single piece of A4 paper. Thats why you need to scale it down.
Mess around with plotting and exporting a bit until you get what you want.

Drawing a building in millimetres is MAD. Unlike in mechanical engineering and related disciplines, the standard metric measurement unit in Civil engineering and Architecture is the metre.

Of course I know I can't draw a building 1:1 on an A4 page. Standard scales are 1:50, 1:100, and such. But at those scales, the drawing I made is tiny which makes me thing I've been using the wrong units all along. My question was how do I set/check that the units are correct, because my drawings are coming out all wrong.

I don't make architecture, i make mechanical and electronic parts

Go to Options > User preferences

AutoCAD unit can be anything, so it doesn't really matter untill the final plotting stages and for insertion of objects.
Write Command > units

@ Captain T

I used AutoCAD multiple times. I like it because its more technical than for example Illustrator.

If you guys want a free version of AutoCad check out DraftSight. It's made by the guys who make solidworks and its almost the EXACT SAME THING!

As far as drawing to scale, stu, just make a note in the title block that says 1mm = 1m, or you can even go 10mm = 1m.

So long as the scale is noted, everything should be fine IMO.

I THINK I figured it out.

This is something you set up along with the page size. It says: [input] mm = [input] units

Meaning that, say, 1mm on paper equals 1 generic unit of that I used in the model space drawing. If I set it to 1000mm = 1 unit, now everything that measures "1" in model space will be interpreted to measure 1 metre, so I can set the viewport scale to 1:100 effectively making it 1cm on paper = 1m.

SOMEONE SHOULD EXPLAIN THIS ON THE INTERNET.

Oh yeah stojke, i meant that for Stu: what does he use for is architecture studies if not AutoCad

Stu: So there are other drafting software out there, i thought AutoCad was the only one

Tetsu0: thanks for the tip on the freeware AutoCad =P

I didn't know about that, Autocad is the standard. I'll stick to it while the student licence lasts

Well You will be surprised how close DraftSight is to AutoCad.
I'm saying it's close down to the typing commands...

IDK if you use AutoCad with a keyboard (typing commands etc...)
if you type: LINE, it starts the line function and you pick 2 points, if you type CIRCLE, it starts the circle tool etc etc....
DraftSight is the same thing. It's reverse-engineered and it works amazingly.

Keep using autocad since it's legit - when it runs out however, you have a free tool (forever) that's 99% the same thing

Oh also, DraftSight can import/export AutoCad files.

Will definitely bear that in mind, thanks.
