Almost completely useless

Only views tcws as-is. Can’t even select objects to get dimensions.

I just downloaded a few . DWG's from my desktop using the AirShare app from Avatron, and I couldn't believe how well TurboViewer displayed them! The speeds are fantastic and the display movements are completely fluid, even with a very complex drawing. Thank you for this free version; I'm really looking forward to the Pro version, so I can see everything rendered realistically with shading. I hope it has support for the iPhone HDMI adapter so I can use it for presentations.

Thank You, IMSI

I've been using TurboCAD for years and I was tired of printing CAD drawings and taking them to the shop to work on. Now I can take my iPad into the shop instead. Being able to zoom, spin, etc is all I needed and this is GREAT! So great I've plunked down the $6.99 for the X version --- not that I minded the banners but I really wanted to reward IMSI for a great app.
