I sometimes use a laptop with a touch screen to work on parts and assemblies, often without a mouse, and end up using the touch screen a lot to manipulate my views around whatever I'm working on. This all works well, except for when I need to select multiple features like for a set of fillets. After selecting one or more features, I would touch the screen to orbit, but when I let go, all of my existing selections are lost.
Is there any way to retain selections when touching and orbiting on a touch screen?
Is there any other way to easily orbit without a mouse that isn't the view cube? It works alright, but its not the best.)
