I've imported a .dwg (CAD) file into illustrator. All the layers show up, but I can't see anything despite going through each layer and turning on and off visibility. I think I probably have something set wrong. Can anyone help me out?
Try doing a ctrl Y in illustrator to see if the paths are there in outline view. You may have a setting in CAD to change, to fix this. Also try a very simple CAD drawing to see if you can get a simple shape to convert.
