Hi Jiaxing Zhang, As I understand it, the "translate selected models" mouse mode is only XY-translation in screen coordinates, so you'd first need to rotate the whole view ~90 degrees to move that model in the desired direction. I don't know of any way to do it with the mouse directly, only using the command (as you said). I hope this helps, Elaine ----- Elaine C.
