Hi again I noticed another problem with my dwg file, I attached a .pdf underlay, and it seams to be fine used it as normal. Traced it and etc. but then I moved the dwg to desktop and opened the file, forgeting that the pdf has to be in the same folder, ofcourse when selecting the layer of pdf underlay, I get this text saying that the pdf is missing, so I moved the dwg back to folder and opened it again, now the underlay seams to be there as it was and also slightly rotated just as I had it, and I am also no longer getting that message of missing underlay. But the problem is that I get the frame of the pdf, but I cant see the actual content,.. the image. All the layers are visible,.. any advice? thank you
