Free and easy-to-use 2D CAD Software?


I have recently started designing a new airplane. Actually I am a paper and pencil guy, but when there's more complicated things to be drawn like parabolic forms I would like to use an easy to use and free CAD software. I don't need 3D stuff but I need to draw simple plywood pieces based on at least 1mm or .1mm precision and be able to get a good result when I print it. That's all.

Any suggestions?

Try Draftsight. It's a full featured 2d program capable of some 3d. 2d is pretty simple, so is the 3d for that matter.

"Easy to use" and "CAD software" don't often appear together in the same sentence...

If you find, one, let us know!

Draftsight.it is free and once you learn how to use it you will be able to use Auto Cad.I don't have any drafting training but have a few friends who gave some lessons and now i am on my own and designing.I have several planes going in the Scale forum where I posted my progress using the program.Take a look.Joe

As I am a Mac addict, I keep my focus on software which runs natively on this platform, but I'm not limited to using these, because I can also run others under Parallels/Windows, as I do with Profili and others. As for Mac OS I found EazyDraw very easy to handle and powerful enough for my tasks.

Hi everybody, sorry to revive an old thread but I wanted to mention a free 2d CAD program that I an co-developing:
It is here: www.siigna.com

It is an online CAD drawing app which requires PC, JAVA and for now also the Chrome browser.
It is easy to use and has several tools for precision drawing.
I did this piper cub three view drawing in it:
You can import dxf and export to dxf and pdf files, or store drawings online.
I recommend saving a copy of drawings locally as the online storage is not yet rock solid.
Feel free to try it at give us feedback if something is missing or wrong.
And remember it is still a prototype.

Best, Ole

LibreCAD is rather good, (fromaly QCAD). Cross platform, Linux, Mac and that other OS. Lot's of help on the net including both written and video tutorials. Won't cost anything but a little time to check it out
