It would be good if we are able to visualize different combine states in single window, which will help to understand the different dimensions of single feature as well as gives better understanding of component. That would be ideal when we are using 3d drawing. Other wise we have to go again with 2d drawings, which give all the views and dimensions in single sheet. Same will be applicable for taking print outs of the combine states. If we are not able to take printout in single sheet then we have to waste bunch of papers even a small components.
