Geometrical Construction in Dynamo

    Recently I've been asked about how to make a Tetra-Pod with Dynamo. After I created one, I felt it's a quite simple but good example of using geometrical construction in Dynamo, so I'm posting about it.

    Basically, the geometry of a Tetra-Pod is from a regular tetrahedron as it's name. So if a regular tetrahedron could be created, making a Tetra-Pod wouldn't be very difficult.

Regular Polyhedrons

It's not surprising that most of regular polyhedrons can't be created easily in Revit. Just few of 3d software have a feature which can create regular polyhedrons instantly.(eg. 3ds-max)

It is well known that there are only 5 regular polyhedrons.

And it's quite easy to make them with paper works.
But it's not that simple to create them as 3D computational model. You have to deal with a bit complicated angles to create one.
