Sometimes, when you try to navigate in a very tight, inside facing mesh or simply an interior it may get difficult. This is where a wide-angle view would come handy. You can change the Field of View angle in a 3Ds view by making the view active and depending on your navigation style perform the hotkey combination below.
Default: SHIFT key + mouse wheel scroll
Autodesk: SHIFT key + right mouse click drag
Leica: SHIFT key + right mouse click drag
