I’m an architect and use Acrobat Pro at work on a daily basis but I have to say that your software absolutely blows it out of the water! I have also used Bluebeam PDF software extensively on my previous Windows machine and again PDF Studio outshines it and is in my opinion, much better value for money. I just purchased PDF Studio Pro for personal use after spending a couple of days extensively trialing a whole bunch of other similar software. So much software is offered without a user guide, depending on a “knowledge base” to help people learn. I’m also impressed with your online user guide, as well as the multi-platform support. I just want to say how pleased I was to see how much substance you put into your software. National Oceanic and Atmospheric Administration (NOAA).
