Inside the cad/cam views, the scroll wheel zoom works like…
scrolling up zooms in, scroll down zooms out.
but in the simulation view, the opposite happens.
the correct version is subjective, doing both is batshit crazy.
suggested fix: reverse the scroll zoom direction in the cad/cam view.
The preferred version is to allow the user to choose which way it goes. I’ve done both at different times with different software. Fusion 360 allows the option of direction change.
