I love how you guys quickly react to all our wishes so my post wasn’t meant as a criticism of any kind.
Maybe it’s because I do use Rhino on a touch capable laptop that my view on things is slighty biased towards touch Input
I used the touch interaction (pan, zoom, rotate) in Rhino to present my work and totally love it. Still I can see, that touch input is not precise enought for most modelling commands. On the other hand, I frequently use Rhino as a vector drawing program because I think the snap functionality of Illustrator is utterly useless for anything half precise.
So in fact, being able to sketch and draw with my finger or a stylus would be totally awesome for me.
On a side note: viewport interaction is a nice thing, but when I start a command, viewport manipulation is secondary to data Input. My Laptop came with a touch stylus that provides a pick precision similar to a normal pen so precision may not be that much of a problem in any case.
So how much of a problem would it be to generally switch the input mode once a command is executed?
There are a few commands such as sketch, that definitely lend to touch or pen input and others, that might work good enough.
