Scroll wheel is such a pain to use. It scrolls huge distance in one scroll as also while panning it moves huge distances which makes detailing a heck of a trouble. And this is not consistent too. Sometimes it works fine but sometimes when you are isolating a geometry and want to detail out stuff it does not. What’s the issue. I feel Sketchup has much better zooming. panning & focusing capabilities.
Not experiencing that here. Could be your mouse driver.
In Rhino, check the setting in Options>View>Zoom:
Making that closer to 1 will result in slower zooming with the mouse wheel
Making it negative will reverse the direction
Making it exactly 1 will disable mousewheel zooming altogether.
that does not depend on any Rhino setting, but on how fast you move your mouse. maybe your mouse indeed has issues?
