LARGE PDF files when exported from SW

We have an assembly that consists of more than 4000 parts. When its put into a drawing and exported out on a few sheets (2-6) which is a building layout for a customer the file size is huge. Average size is around 14 MB. That size of file is not easily emailed. I wonder if there is some sort of bug that is boosting the file size. The reason I am thinking this is because I found a way to reduce the file size. To do that I opened the PDF in adobe, then I did a File\Print as PDF and the file was reduced from 14 MB to 4 MB.

Yes I found a workaround, but why is SW exporting such huge PDF file sizes?? I don't recall this problem in the past. Anyone else seen this or know of an SPR?

Thanks,
