Unwanted vertical lines when plotting pdf's from my viewport

[tanner_wright8DXZC]

These unwanted vertical lines keep showing up in the pdf's I am generating from plotting my viewport. When I go to plot preview they do not show up but when I open the pdf they do. I have tried multiple pdf software's and it is the same every time so it must be some hidden issue in civil 3d. If anyone has any suggestions it would be much appreciated.

How is the aerial file setup?

It was an xref of a pdf saved from google earth.

It could be the PDF on how the image was printed to create the PDF. Can you see the seams in the PDF? You may need to zoom in a bit.

Here is the original pdf. No lines evident. I am confident I accidentally clicked something in civil 3d that turned this on.

Not from Civl 3D but from AutoCAD LT, I found this to be an issue for PDF underlay. Instead of using Menubar>Insert>PDF underlay, I used tab>Insert>PDF Import. This put googles aerial as in as a PNG. Solved both this issue and dark colours coming up as white.

I would suggest saving the aerial from Google Earth as a raster file.

Google Earth is free and can easily be downloaded and installed. Don’t use PDF, use your own ‘saved image.’
