Then came the question having a stair along the walls, the faces of the Polyhedral, what is its angle. Ended up with the stair on level 3, the stair-halves have an angle of 120 degrees. Interesting was dealing with one halve along a wall pointing inside and the other halve along a wall pointing outside. It is at the end a little bigger than expected, and for the static an Icosahedron as a centre, bearing up the Dodecahedron. An optimal scale is 77 step rises of 0.17 meter between the planes of floor 3 and 6. With the given 0.17 step rise, the formula step length of 0.63 meter = 2 x rises + 1 x going brings a step going of 0.29 meter: 0.63-(2*0.17)=0.29. Because I’m a European, grown up with the metric system, the measurements are in meters. Some puzzling with a free standing elevator and chimney; afterwards came the ramp to level 1. This one is that expensive in render time, defined by a lot of small cylinders, I quit further development and started to render the 60 seconds animations. 18 Months later is here the result: ErO’s Penthouse.

Floors Level 3, inside Squared grid is 2 by 2 meters. · Floor level 0: lowest step rise is in the underground, and the upper two step rises are part of the room. · If node of Dodecahedron is present it has three step rises, other floors are two step rises. Floor 4 and 5 has only nodes of Icosahedron, also two step rises! · Note the little difference in height of the DodecaHedron-nodes and IcosaHedron-nodes in floor 3 and 6: heights of IH (= ±6.531750) & DH (= ±6.558250) gives a middle for the floors of 3 & 6 on ±6.545000, total rises of stairs on level 3,4 & 5 = 29+18+30 = 77, delightful…, exactly 77*0.17 = 6.545*2. · Floor of level 9 is top of Dodecahedron, no floor, no “Stairway to Heaven”. Baffles · Standard height is 2.5 meter and has a variable width. · Exception: left of stair going down to level 2 on floor 3!
