CutePDF installs as if it was any other printer and can be used by any windows program (not sure about Apple). I use it all of the time with Autocad and MS office. After you print it askes you where you want to save the pdf file.
Autocad cannot open a pdf file and therefore it will not show up when using the Autocad file open function. PDF files can however be inserted into an Autocad drawing by pasting from the clipboard. It is displayed as like jpg image and not to scale. The individlual lines cannot be selected.
It is possible to trace over this imported image but the drawing produced is not very accurate.
