Vector PDF for line drawings

Hi, does PDFCreator support creating vector PDF's?

I've been pushing for my work to use DWF's instead of PDF's for years for line drawings, partly because DWF's are so much smaller for line drawings since it's vector based rather then bitmap based. If PDF's are now able to be created in vector format, that's one less reason.

I ask because I noticed the size differance between DWF and PDF is much smaller then it was years ago.
