I have a model with sub parts/Objects that are substantially smaller than the entire assembly.
While working in Edit mode I’d find it convenient to be able to have a one-key “Frame Current Object”, without zoom all the out as “HOME” would. I’d like to have all the parts un-hidden, so I can see how the sub parts relate to the greater assembly.
If someone were to implement this, I nominate “Shift+Numpad .” as a semi-logical hotkey.
ALT+MMB is useful, but ideally this function would toggle between “current viewpoint” and “frame Current Object”, so when working on a detail users could “back up” and “go back” with maximum ease.
