It would be a nice feature to have a control panel in Inventor where you could take certain driven constraints and put them on this control than hit a momentary button to make your model move. Once example would be a hydraulic cylinder. Presently, we drive the cylinder to put things into motion, but I have to access thru browser and usually add symbols to make the constraint stand out (See image). If I had a control panel where I could tie that driven constrain to it and depress a toggle/button which would activate the constrain. I would then have full control and almost act like it would in the real world.
