This software looks interesting. I’m using the able2extract PDF Converter and it’s great so far. I use it to convert the vector images and text in pdf documents into the DWG or DXF formats. Able2Extract also covnerts most other formats, so it’s really convienent to have all that in one software program. There is a free trial version here.
