Within Inventor, when using 3D navigation devices, when the user pauses navigation in perspective view, the view center resets to the object in the center of the graphics window. The result is seriously easy navigation around a complex 3D model... as well as navigation inside models. It's a great experience and one I miss outside of Inventor.
Navigation is pretty fluid in Fusion's Ortho view mode, but it's clunky in perspectie mode, because this feature is missing. Please add it
