Free CAD software?

Sir Thrift a Lot
Does anyone here know if there is a free or at least cheap CAD program with a short learning curve? I need to make a technical drawing for a metal shop. TIA.

Thank-you for the links. That Google version might be worth playing with.

As for AutoCAD, as a first year student, I'm running the free student download of Mechanical 2013. As long as you are a student (I assume you are not), you get a free 3 year license of the educational version. I have it on both a desktop and laptop. It's been great fun learning what I have so far and I have seen what real skill can do with it.

Good luck.
 
I was a student when I downloaded it two years ago. Challenging, but lots of fun. I wonder if it will still load...
 
It's good to have that recommendation. After looking at Fisherdude's link, I was torn between Google SketchUp and Draftsight. I thought maybe the Google would run on my Android, but I like that the Draftsight comes close to the industry standard.

You already used AutoCAD, so you may not be in the best position to tell me how the learning curve is, but perhaps you can give me some tips. Any pitfalls to watch out for? Thanks.
 
Try Q-cad. Linux version is free and there are many tutorials to do your first drawing.

I don't know If the windows version is free as the linux one.
 
I used Draftsight as well. It is only a 2d program, so if you need to work with 3d you're out of luck. Draftsight is almost an exact clone of Autocad ...the commands all worked the same, but some were labeled differently, and there is a short learning curve, but much is very intuitive. Want to draw a line? Type 'L'. Want a circle? Type 'C'. Things like that. It also uses a .dwg file, so any Cad variant should be able to open it. I don't remember what type file Sketchup used. I fought with that for a month before I gave up. After Autocad it seemed soooo primitive.

And I found bunches of tutorials online for using Draftsight.
 
I just registered DraftSight. For occupation, it didn't offer an "other" choice, so I am now a Technical Support Engineer.

I'm pretty sure that 2D will be fine, but having never done this sort of thing before, I'm not 100% sure. It seems that in 2D you would just make a separate drawing from each aspect, wouldn't you?

Yes, that's the way I had to do this until recently (I was able to bring SurvCad home from work). You can still draw with perspective, but you'll have to know how to draft manually to know how to construct this. Easier to just draw each face of whatever object right next to each other in the same .dwg file. You can plot whatever part of the file you wish. What are you going to draft?
 
Important tip:
Make sure whatever computer you are using meets program requirements. It is very frustrating to deal with a cursor that doesn't quite keep up.

I'm on a Win7-64 box with a dual core 2.4. Not modern, but not ancient either.

Then you'll probably be ok in this regard. When I used Draftsight, I had to use my little notebook with an Intel Atom @ 1.6GHz and 1G RAM. Absolute bare minimum. The mouse would not quite keep up.

The parts you mention should be a piece of cake.
