What is the difference between 2d Autocad drawings and 3d Autocad drawings

[jtesttubes]

I want to know this information, I am going to study autocad, my friends are telling to learn how to do 2d and then go for 3d , what is so special in 3d AUTOCAD drawings, anyone here in this forum can explain it.

AutoCAD's 3D is pretty archaic. The 2D is pretty simple to understand. Lines. That's about it. In their version of a 3D model, you can simply extrude your lines from the working plane to some other. It's non paramteric and not very easy to use. Honestly, I applaud you learning 2D first, but don't waste your time with AutoCAD for 3D. You can get a bit of a feel if you use Inventor or Mechanical Desktop (if it still exists) but I would recommend something along the lines of Pro/E or Solidworks for your 3D learning.
