David,

I just now reread the your post and missed this part.

I didlike both just as well only I can't edit a PDF if I want to change something on the plan, a select a portion of the plan to copy and paste, and finally PDF's don't import into Autocad at all. TIF files on the other hand work great for that. I can load a TIF file into Autocad with an Autodesk add on program called Autocad Raster Design. This program imports a TIF file at it's correct dimensions so I don't have to mess with resizing the picture to ge it's dimensions right. It the TIF is 36" x 72" that's just what I get when loaded into Autocad. It's a real time saver as I can goto tracing the plan right away in Autocad.

Since you have to pay for the new Adobe Reader, version 9 I believe, i am hesitant to use PDF's anymore. As a matter of fact, most of my recent business correspondance has been requested in MSWord format (8.doc).
