Thanks, that program works great for converting PDF drawings of pumps and valves from a company's website. Only downside is it doesnt work so good for scanned blueprints or any kind of grainy drawing.
I need to convert a PDF to a DWG. I have found that aidecad (http://www.aidecad.com/pdf-to-dwg.html) works pretty good. The trial version allows a limited number of conversions.
