In my business I make a lot of 2D cakes. For these cakes I always make a template to put on top of my cake before I cut into it. Some templates I make freehand and some I make using the kopy kake machine. Either way, I always cut a piece of cardboard to the size I need and sketch out the design I need onto it. After I finish, I cut out the design and place it onto my cake. Once I have cut out my design from the cake, I may need to cut some free hand work but I never do it all freehand!
