The tool handles do not scale when using a 3d connexion space mouse / navigator. When using the normal navigations tools, they adjust their size while zooming. I have to say though, that this is also not very comfortable, as those can get very small, if you zoom into an object.
Steps to reproduce
- make unit cube - hit y to bring up transform tool - zoom out/in using ctrl+alt+mouse drag (left or right)
- notice the handle size seems to be relative to screen -> desired behavior
except if you zoom in over a certain point (object size hits 90% of viewport) - then the handle starts getting smaller the more you zoom. -> not desired. I'd expect the handle to stay roughly the same size relative to screen
- use a Space Navigator or Space Mouse to do the zooming. - notice the zoom handle size is now tied to the size of the unit cube. -> not desired. I'd expect the handle to stay roughly the same size relative to screen
