We need the Star Trek TNG "Okudagram" interface before it becomes practical. And then there's the capital investment cost.
"Touching AutoCAD on the desktop"... erm... not sure I should "touch" that phrase, given the drizzle of forum spam.
Dean, both of those links talk about the pinch-to-zoom feature, and both say 'bring together to zoom in, move apart to zoom out.' This seems backwards to me. On my Android, and on other touch-screen devices I've seen, it is always pinch together to zoom out and pull apart to zoom in. Is this a typo, or an Autodesk 'feature' added to confuse?
Credit where credit is due! Give kudos or accept as solution whenever you can.
I use a stylus a lot on my tablet. My fingers are on the larger side. I've also seen where someone used one of the 3d scanning interfaces from a gaming box, I forget which one, for an AutoCAD interface. I think I'd like that better.
