drag and drop system

Hi! I’m trying to find a way to make the object visible on the game map when the user drags it using the drag-and-drop system. Right now, only the image appears. I also want the user to be able to see what the developer sees when designing the map—specifically, the system that allows objects to be rotated and moved along the X, Y, and Z axes. Is there anyone who can help me? I’m attaching what I’ve done so far to build the drag-and-drop system.
