You've noticed that when you perfectly align nodes of shapes witouth 'touching' one over the other there's a white space between them?
The first 3d rectangle has nodes perfectly aligned, the second too, but it also contains all three shapes merged into another to hide the withe space..
Is the only one solution i've found to this, of course you can move shapes 1mm to put one over the other, but in that case the nodes are not perfectly aligned.
With perfectly aligned I mean that you put a node over the other when you're moving the shape, OR when you align them with ruler or guidelines.
