Try this:


(
	global gloVar_AutoVptSnapChange
	
	fn gloVar_AutoVptSnapChange =
	(
		function SetSnapTo2_5D =
		(
			if snapMode.type != #2_5D do snapMode.type = #2_5D
		)
		
		vptType = viewport.getType()
		if snapMode.active != true do snapMode.active = true
		case vptType of
		(
			#view_left: (SetSnapTo2_5D())
			#view_right:  (SetSnapTo2_5D())
			#view_back:  (SetSnapTo2_5D())
			#view_front:  (SetSnapTo2_5D())
			#view_bottom:  (SetSnapTo2_5D())
			#view_top:  (SetSnapTo2_5D())
			default:  (if snapMode.type != #3D do snapMode.type = #3D)
		)
	)

	unRegisterRedrawViewsCallback gloVar_AutoVptSnapChange
	registerRedrawViewsCallback gloVar_AutoVptSnapChange
)
