Cube Net Puzzle
Construct the net of a cube. (Remember you can start only from solid objects)
Solution
First, we have to create a planar object consisting of two squares. For this, we can join two cubes and delete elements that are not necessary (e.g., vertices).
Secondly, we promote the last object to the default Build module and build the desired structure by applying iteratively Delta operations. A final Weld and Simplify will remove duplicates.
