When inserting a tiff file into a drawing on autocad 2012, the inserted file appears to have wide lines. When plotting this drawing, everything is fine except for the tiff file. It prints heavy or wide lined and any fine detail bleeds together. I can plot the same drawing on Autocad 2004 and have no issues. Any suggestions? Another problem I have is extra marks or ghost lines that appear on my screen. This usually happens after I have inserted one drawing into another. If I extent all, I have to erase the extra lines or marks left on the screen. Anyone else having this issue?
