Step 2: The Unfolding
The most important tool is the knife: You can choose which edges have to be open on the 3D model. You don’t have to select all open edges, and you can still join edges back in the unfolded view.
When you hit Unfold, you can choose between auto and manual, you should choose manual, or you will get 10 cm big cubes. You would need a tractor wheel for making a zoetrope with them. My cubes are only 3 cm high, for example, that is about 1 inch.
On the right half, you see a preview of the instructions now. With right-click, you can modify the flaps, rearrange faces and flaps etc.
In case you have a similar model like mine, you could get in trouble when you don’t know any more in which angle you have to put it after you have glued it together. So I unfolded every cube in the same way: The top face has all the side faces on its edges, and the front face has the bottom face attached to it. So the face with the 2 faces over and under it is always the front face... Sounds complicated.
Really important: Do always number your phases for example on the bottom of it. There is a function for writing text on the unfolded sheet.
I also printed one of that sheets with the blue quarter circle, then I could use it as a stencil to arrange the cubes later.
