I use Adobe Acrobat (which installs a PDF printer) so its as simple as printing the drawing/model and selecting the PDF printer. thats it
cutepdf is freeware that works just as well that Ive used.
there are many others.
For every drawing I do I make a pdf. to send to vendors and as a good way to keep old revision information. All prints are saved as follows Part1 rev b.pdf so I always have old versions
Thanks, mcgyvr. The main thing I'm looking for is that a drawing converted to a PDF remain a vector image. But I figured that there were other differences that might not be obvious from a web page.
I've been using CutePDF since it was suggested and like it. The reason I asked the original question is that I'd been using SnagIt. SnagIt rasterizes everything. Obviously, this is undesirable when it comes to drawings.
