The 3D scope view is a separate window that can remain open alongside the main window, if you wish. It provides a visual representation of the movement of your mount and telescope relative to the pier. The dimensions of the telescope, dew shield, focuser, camera and pier can all be edited (and saved for future use) to provide a fairly accurate graphic of your instrument. However, we do not recommend that you rely solely on this graphic as you move into tight positions near the pier. Nevertheless, this is a very useful (and fun) tool.
