problems import dwg file of autocad 2013 mac on skatchup 8 pro

[edd]

Good evening, everyone! I have the above problem when I want to save autocad files in 3ds via sketchup and then open them with c4d to render,
What's the problem? to me says that the file is not recognized.
I look like answers!
Greeting! ! ! !

What's the problem?

of the 3 programs I use only autocad and therefore I do not know the problems of conversion to pass to cinema4d.
But I was thinking that you could try to jump completely sketchup and export from autocad in stl format that c4d should quietly read.
