Hi Uncleho,
it depends what method do you use for translating. I have find just one reliable way to do through cgm format. (drawing in part - export cgm file - new prt file - import cgm file - save as dxf file). When exporting to a cgm, set drawing sheet, and than colors by widths. After this you get a cgm file with original widths. After loading this cgm into prt file assign to each width a color (usually 3 widths) You can do this by Class selection-other-thin, normal, thick stepwise (It's very easy to make a Macro). Than you get a drawing with three different colors which save as name.dxf, dwg. In a autocad file assign to each color thickness, layer and so on. It is a best to make with several drawings in one file... I have tried to translate dwg directly but it doesn't seem to work.
