There is a new AutoCAD reader around called TurboViewer. Not available for PlayBook of course but I emailed them and got this response:
"We do not have a TurboViewer version for Blackberry playbook. If we get enough requests, we will consider it though."
Which is more positive than the response from Autodesk. So if you want one please email IMSI Design, [email protected], and get them to consider it!
TurboViewer - The 2D/3D CAD viewer optimized for speed and mobility
Thanks
