Emergency lighting Plot error

[david.faircloth]

I recently ran across an issue I've never seen before. I was producing lighting plans that had hatching to identify the emergency fixtures. When plotting out the prints i noticed on one of the pages the hatching didn't show up. Seemed strange to me because both lighting pages were 100% setup exactly the same using a view template so no difference between the plans. Whats even more crazy is when you look at the plan in revit it shows the hatching for the emergency fixtures but as soon as you turn it into a PDF the hatching is lost for some items not everything. There are only 2 lighting plans on the job and only one of those are an issue. Its strange because both drawings share the same view template and the exact same fixtures so that eliminates it being a family issue. 

Currently the plot setting is setup for vector processing. if i change this the raster then it does resolve the issue however the next problem is the file is crazy large and the background is lite. theirs no reason why i should be using raster to resolve this issue as one print it does fine.

Do you plot directly, or do you create a PDF first? i create a PDF first to reveiw before actually plotting. Maybe try that. 

Does the problem appear on the PDF as well?

We create PDF's. Almost everything we do stays electronic. We don't plot hard copies much anymore.

thanks,
