Revit 2018 PDF/DWG Export issue, double lines instead of single

[Anonymous]

Publishing PDF from Revit Structures with Adobe PDF or to dwg, the drawing comes out with two lines instead of one as on screen. Only for some of the drafting lines i.e. red dash has black as well, blue dash has black line as well (almost as a shadow but a diferent line type). Any sugestions/help? I use Vector output not Raster because raster output brings in other phantom lines not visible on screen in revit. Current export issue is from Revit 2018 but had the same issue in 2017. (For Clarity the red lines on the attachement are from dwg import, completly clean linework with sinlge layer and purged dwg, the blue lines are drafting lines from revit). Thanks

I recommend you that you clear your lines that you can use raster, and you don't active shadow in the views that you want to publish, the thing is with vector you loose some information and another is flat or similar without line weight this is one of the common problems to print that i see it.

I don't have shadow lines turned on, i tried a few other things without success and looking at my properties i noticed i had "Show hidden lines" on "all" which i needed as i had things under the slab. I put it to "by discipline" and now i don't get double line but can't see base of columns under slab, thanks anyway for your time @Luiscko.

ok the problem with this filter is like you say only the discipline that you chose is show it in this view if you want to have all of this you need put coordination and in visibility and graphic uncheck the elements that you don't want because this elements are the lines that you have in your  dwg and your sheets.

It is a known bug when you export with Show hidden lines : All

Just put None and it should work fine, the bug is fixed in 2020.
