I am having trouble working with a large civil3d file.
My issue is that when I print a pdf file from my dwg file (which is apprix 140mb large), the pdf file that comes out is more than 30mbs. My work laptop can't handle a pdf file this size, let alone print it or email it.
I am after some advice on working with large civil3d files (it is the surface model of some scan data which is slowing it down). I can accept that the civil3d file is large and difficult to do work with quickly, but not being able to print out a pdf file which i can easily send to my client is very annoying.

So just to repeat, I am chasing advice on:
- working with a large dwg file, I am dealing with surface models generated from scan data.
- how to print a small pdf file from my dwg file.
Any and all help will be greatly appreciated.
Solved! Go to Solution.
George, I'm downloading now. Will let you know if I have any suggestions.
Try these settings...
George, Hope this helps. I've run into this same issue and haven't attempted to do what Todd suggested so that may be a better "fix". What I like to do is once the large PDF has been created, export it from Adobe Acrobat as a high resolution JPG. This gets rid of all the massive data that autocad creates when printing elevation banding. Then using Acrobat again convert the JPG to a PDF and the file size is quite minimal. See attached. I used a JPG medium quality setting and ended up with a 400KB document instead of the 30MB.
I think rasterizing a vector map (specially in a lossy format as JPEG) is definetely never a good idea, sir.
You should try to set a lower resolution in your PDF virtual printer, increasing it gradually up to the desired compromise.
Thanks for that Dustin. That's what I was looking for. I was trying to compress the pdf file but it kept crashing my computer, didn't even think about exporting it.
Thanks for the link Todd. When I get more time i'm going to go through those settings and see if it helps me. I'm always cautious about getting too deep in civil3d settings, i don't want to break it!
In addition to the other advice For the heck of it, 300MB dwg sounds like there may be some header issues; try Audit purge all purge regapp, wblocking the file contents out and see if comes down some
Thanks for that Joseph. I did try that initially on the lowest DPI setting but it didn't change it to significantly for me. I might try it again just to check i was doing it correctly.
