Hello, I am watching the tutorial videos on Youtube and see people easily copy items when they are in X mode (with the axes showing) but that does not seem to work for me. I can only place one and not more than one. What am I not doing wrong or why does it not copy the item? Also holding SHIFT key to multiselect items does not seem to work. It will only let me select on item and not multiple items. Why are these two things not working for me like in the videos?? Hope anybody has the answer. Thank you!
