My father, an architect for 35 years, would appreciate this. Then again, he told me that my Tablet PC pen was "dry and out of ink" the last time he was has over. Hmmm….anyway: Bluebeam Software announced Tablet PC functionality in their various CAD software applications. What’s really interesting about this is that Bluebeam’s software allows you to convert complex CAD drawings into Adobe PDF format, making the Tablet functionality perfect for annotating drawings. Not having the PDF format natively in Office 2007 doesn’t sound too bad, now does it? Well, at least not if you’re an architect or CAD designer, that is.
