I'm plotting a drawing in which I have land parcels provided in the form of a connected ArcGIS shp file. The parcels are closed polygon features. I'd like to plot the parcels as phantom linetype. The problem is where neighboring parcels have common boundaries, Autocad Map does not filter out the overlapping boundary segments for the purpose of plotting. As a result, the linetype becomes a mixture of phantom and solid lines and everything in between. I've tryed using plotstyles as well as styling the polygons. I don't think plot styles work with map features. The styling works when the lines do not overlap. Exploding the polygons and removing duplicate segments is not a realistic solution when working with data that is shared by true GIS programs like ArcGIS. I've seen some old postings that indicate this has been a problem for years. Does anyone know if there is a good solution out there.I'm just a part time cad operator. Sorry if I'm missing something. Thanks.
