How to obtain the origin of a selected subassembly

Hi, I have an assembly file with lots of subassemblies. I can click on "Origin" of any subassembly on the tree for SW to display the corresponding origin. How do I make SW to display the coordinate values of the origin of any selected subassembly? When I want to measure the distance between two points in 3D space, how can I input the coordinate values of the points?
