Over a 1cm scale:
12 patches almost fit in a unit cube, but not quite.
Pairs of patches, e.g. netP1 and netP2 join up well, with horn to horn distance of 1cm, but the two vertices are off from the corners of the unit cube by ~0.0167468cm.
After line_line these two vertices, the 3rd vertex is about .023733cm short of the center of the cube.
Patch(P1+P2) does not quite adjoin patch(P3+p4), etc.
Will check number of decimals of point coordinates tomorrow.
