autocad 3d exercises for download?

I'm looking for something like this in a link below and similar sketches if
someone knows if they could be downloaded from somewhere or if someone has lots
of this sketches and is willing to send me a few through an e-mail

thanks in advance!

There's some working drawings here although it's on the Inventor forum
I'm assuming your looking for jpg pdf drawings and not .dwg files.

http://worldcup.teknigroup.com/worldcupfiles.asp

the links labeled "challenge" are .pdf's of working drawings

the links labeled "solution" are Inventor files of the parts in the
drawings, which you probably can't use.

some of this stuff is difficult to draw in Acad, compound curves etc.

are you studying?
