Icosahedron[ <Point>, <Point>, <Direction> ]
Creates an icosahedron having the segment between the two points as an edge.
The other vertices are univocally determined by the given direction, that needs to be:
  • a vector, a segment, a line, a ray orthogonal to the segment, or
  • a polygon, a plane parallel to the segment.
The created icosahedron will have:
  • a face with the segment as an edge in a plane orthogonal to the given vector/segment/line/ray, or
  • a face with the segment as an edge in a plane parallel to the polygon/plane.
Icosahedron[ <Point>, <Point>]
Creates an icosahedron having the segment between the two points as an edge, and a face contained in a plane parallel to xOy plane.
Anmerkung: This syntax is a shortcut for Icosahedron[ <Point>, <Point>, xOyPlane], which requires that the segment between the two points is parallel to xOy plane.
Anmerkung: See also Cube, Tetrahedron, Octahedron, Dodecahedron commands.
