Hi!
Cool course, I really like it. I have a problem and I can not figure out what is wrong. When I am trying to duplicate an object with the same data (Alt+D) it creates an object with the same data, as it supposed, but when I am trying to modify it, move a face or something along this lines, I am not seeing the change on the second object until I quit edit mode. What can I do to see it at the same time?
