Thanks Piotr..
Yes, that's right - when I have different materials in 3DS then I have it also in .gdl...so now when I import .dwg in 3DStudio Max then I change some of materials, and that's it....
Thanks Matthew,
probably you are right - I 'hm not so good in .3ds format, so it's possibly that I by importing object don't check or check something what i shouldn't...
Anyway, I do it like I said whit changing materials in .3ds
Thanks again
