I switched from C3D 2024 to 2026 last week. I am now having issues plotting to PDF. I have only noticed the issue with contours, they are plotting black when they are supposed to be grey. I attached a screen shot from my PDF viewer (Adobe) but the issue is present with any PDF viewer. I have gone through and changed the PDF properties back and forth. The plot style is most likely not an issue, checked that in various ways as well. The issue seems to mainly appear from DEM contours. I have tried extracting the contours but have had the same issue. The drawings plot fine when sent directly to the plotter. I was able to get the contours to PDF correctly when I plotted them from a blank standard Civil 3D template but when I added the additional layer, it plotted them incorrectly again.
