WIP for Plates 4-6

This is a single unit for the 3D version. This has taken most of the weekend to figure out the geometry for. I'll colour code it to show the difference between Forum, Vorum and AntiForum(?) for the next upload.  It's different from the previous 3D entry in that this one is able to continue to grow in a similar fashion to the 2D version. Working on this multiple version in Rhino...  I can then manipulate the angle and length of each route to inform the boundaries which are shown in green and their adjacencies with each other...  Getting there (I think).
