Random plots to PDF to color

[jack.long]

Hello all, 

I have  issues with publishing to PDF. Randomly it plots to color when all of my plot styles are set to plot in black.

My only work around for this is closing down CAD and reopen. This is time consuming when i plot large sets and then open the PDF and its in color. 

I always publish through sheet set manager, although it happens with publishing from layout as well. 

I have plotter config set to use ePlot (PDF) DWG to PDF. and removed all other plot styles.

This only happens randomly all other times it plots normal.

Thanks

I have several coworkers who are experiencing this issue. It seems their first attempt to publish from the sheet set manager prints fine but random subsequent publish jobs print color.

I verified:

Our ctb is setup correctly, colors 1-249 are set to print black.

My coworker's search paths are pointed to the correct folder containing the desired ctb file.

Our page setup is using the correct ctb file.

Beyond that, I've read it could be a profile issue or possibly an issue with Adobe but I haven't researched those issues yet.

What else are we missing?

Thanks

Open vanilla Autocad and set your plot preferences there too. Problem solved. I don't like it and don't know why it's tied together but it is. Before setting my Autocad options, I experienced the same thing...plots or pdf's showing everything in color occasionally. I would restart Civil 3D and 90% of the time, the plots or PDF's would be back to black/white. Sometimes it would not and I would have to restart Civil 3D again. Back in early summer, I set my Autocad options to same settings as my Civil 3D options and I haven't had any issues since then.

We saw this with 2022 and again with 2024 when publishing in the background. Try setting this to publish in the foreground. If you look at the error report it might show it isn't loading the profile. 

We added this to our acaddoc.lsp which is loaded each time a drawing is opened. 

(setvar "BACKGROUNDPLOT" 0)  ; Controls whether background plotting is turned on or off for plotting and publishing. 0 = foreground plot AND publish 

Wish this could get fixed but we are stuck with what we get.
