I am a second year student of architecture and have spent 7 solid days on a project on autocad and have finally finshed all of it and would like to render it for images for a coursework project.
 
But every time I try to render, it brings a black screen. I dont know what I have done wrong. I tried to copy it to a new file but all the materials have been removed and would take me days to get it back to how it was.
 
Does anyone have any suggestions, I am desperate as my hand in is in 4 days!
 
Thanks,
Phil

Does your pc have a video card?, what version did you use autocad?

yes, it works if i copy it to another file. do you think I should try it on another pc?

why should I try it?
