Penrose fivefold star dimetric simulation
This is a setting to represent a five-fold symmetric design of congruent rhombi as a dimetric view of a 3D mesh including 4 rectangles and 1 rhombus. Note that they all appear as rectangles when seen from top. Required camera pitch angle is asin(tan(18°)) ≈ 18.961° for this dimetric view instead of ≈ 35.264° for standard isometric view, so the additional rectangle on top labeled "Camera plane" has been rotated by the appropriate angles (yaw 45° + pitch) and helps you rotate the view as required by clicking on it (or in classic mode using the "View in front of" command). The faces from this basic shape can then be reused to build larger structures like this 3D artwork.
