If you want to create some quick and easy drawings in a super simple program then you need to check out Autodesk Freestyle. This new software program is perfect for someone who doesn't know AutoCAD (and maybe doesn't want to take the time to learn) and yet needs to create some type of design. You can easily create DWG files - to scale even! Take advantage of this technology preview now.
Check out the video as well! This is the perfect program for those of you who want a low stress means of drawing. By the way - this program was originally called Cooper - so you'll hear Freestyle referred to as Cooper in the video.
I am looking forward to seeing what any of you create with this great new design program - feel free to share!
