I've had this issue on and off for some time. When I try to save a dwg to pdf the end result is rarely as the dwg looks. Issues with hatching, dashed lines and saving the entire picture when converted to pdf are blighting me at present. I have tried CutePDF, Bullzip, PDF123 and PDFill, ll with the same results.
Is there any chance you could look at the attached dwg and see if you can save to pdf? If you can I'd would love to know how you did it!
Please note that some minor formatting may be needed as the lines come out bold when freshly loaded. I suspect I've not done something I ought to have at some point in the creating of the map.
Many thanks in advance and all the best
