SketchUp’s navigation around 3d space is legendary.
Orbit, Pan and Tilt are all smooth camera movements becuase they use mouse input, but Zoom is chunky because it uses the stepped input of a typical scrollwheel.
I dont mind using the scrollwheel for modelling purposes becuase I can scroll in and out by “steps”. It doenst bother me that the motion is a bit “chunky”, becuse it’s fast and fairly precise.
But (!) when presenting to others, or wanting to record a video, or just view a project as a nice walkthrough…this scrollwheel jerkiness is offputting and visually fatiguing… I’d like it to be smooth …and (ideally) to link Orbit, Pan, Zoom together, as per the Spacemouse.
So I propose that Alt+Scrollwheel click+Moving the mouse will zoom in and out.
Please let me know if that’s something that could be achieved via an Extension, or, if you have any better ideas about how to link some of the camera functions together (eg to perform a smooth motion for zooming in while panning).
Other discussion topics have mentioned the use of the Trackpad to control camera movements…that might be more complicated to operate (and relies on having a trackpad).
