I have building stl file I overlapped the pillars (50) (earlier the pillars were weak I added 50 thick one) one by one to the different places, now I want to scale them all together with the main object, how do I select all at the same(Do not tell to press shift key and select all of them with mouse), give any thing like CTRL Plus A or something to scale them together and move them together.
