There is a lot to be said for going with an AutoCAD based timber framing package. I am able to integrate 3D Architectural Drawings with my 3D Timber Frame models allowing the client a better perspective of their design. I am also able to generate accurate shop drawings from the same model. If I decide to make changes to the model, they are automatically updated in the 3D model and therefore in my architecturals due to this dynamic link.
I am also able to integrate my drawings with the engineers' site plans since the majority also use AutoCAD. I have access to millions of existing users who are already trained AutoCAD users, thousands of books for additional support, hundreds of colleges, consultants, and training centers, and am afforded the ability to exchange drawings with other designers, timber framers, and architects.
Also as the "de facto" industry standard, most other programs provide an option to convert their drawings to an AutoCAD format, albeit quirky at times.
Anyway, thats my totally biased opinion...I could keep going...but I'll spare you!
