I’m not even a builder, but I did ask my employed builders and somehow NONE of them knew that there are building hotkeys in studio. I can’t really believe I have to show these off but if you use these hotkeys, your building speed will double!
Ctrl+5 selects the transform tool, if you for some reason use that.
A few other useful hotkeys that are useful to mention:
Ctrl+G - Group selected objects into a model.
Ctrl+U - Ungroup selected models.
F - Focus your camera on a selected model or part.
Ctrl+Shift+G - Union selected parts.
Ctrl+Shift+U - Seperate unions or negations.
Ctrl+Shift+N - Negate selected parts.
Not a huge tutorial, but I hope this tip will improve your building speed cause it did for my employees!
