I’ve started a drawing lessons and I have a problem with figuring out how shadow will looks like depending on the sun angle and direction. And I just wondering is it possible in Rhino to have a view which provide a straight line connected shape corner and its analogue corner on shadow. If I move my object and change a sun properties shadow and above mentioned line will update. It will be very helpful to learn how shadows fits depending on object complexity and sun direction.
Is it possibe to do this?
I attach a drawing represents better my problem.
