I just don't have the time unless there's a huge interest in it, which I suspect there isn't. If you want to display edges using cylinders then you also have to make sure the cylinder colour is set to match the line colour. While the parallel option is useful, it's not exactly what I was asking about. I guess vector wasn't the right word, I meant all the edges that share the same direction in the symmetry system, like a zometool direction.
So all edges of same type would be included plus any other types that share that "direction". Re: Zometool Post by robertw » Thu Aug 16, am I don't see how the word direction makes sense here. Sounds like maybe you just mean all edges of the same length.
Is that right? I think Zome rods are the same colour if they're the same length. A connector ball allows for construction in 92 different directions. Each color of strut comes in short, medium, and long sizes. For each color of strut, the ratio between the lengths of one size of strut and the next smaller size if there is one is the golden ratio , which is about 1.
An elegant consequence of this fact is that for each color, the length of a long strut equals the length of a medium strut connected to a short strut. In brief, a long equals a medium plus a short. Similarly, in red, a medium equals a short plus a hypershort. Different types of struts are required for the construction of different types of structures. For example, a regular dodecahedron can be built with blue struts of the same size, a rhombic dodecahedron with yellow struts of the same size, a rhombic triacontahedron with red struts of the same size, a regular tetrahedron with green struts of the same size, and more elaborate structures with combinations of strut types and sizes.
To make it easier to specify parts for a project, the strut types "blue," "yellow," "red," and "green" are abbreviated "B," "Y," "R," and "G," and the strut sizes "hypershort," "short," "medium," and "long" are denoted "00," "0," "1," and "2," respectively. For example, a long blue strut is a B2, a medium yellow strut is a Y1, a short green strut is a G0, and a hypershort red strut is an R Prior to , Zometool offered blue, yellow, and red struts in a size 3 that was longer than size 2 by a factor of the golden ratio.
Per the comments about the golden ratio above, in a given color, a size 3 strut has the same length as a size 2 strut connected to a size 1 strut. Nevertheless, it's unfortunate that size 3 struts were discontinued.
They allowed simple models to be built on a grander scale, and a few constructions such as the compound of ten triangular prisms—see Projects , below require them. Since the ratio between the lengths of one size of strut and the next smaller size is the same for all types of struts, a Zometool model can be scaled up respectively, down by replacing each strut with the next larger size respectively, smaller size , provided that size strut exists.

George W. Hart works in a wide range of media, including Zometool. His name appears several times on this page. Pentidisc The world's largest Zometool construction is a pentagonal "disc" almost six meters in diameter, covered in quasiperiodic tilings , and containing over 90, parts.
It was assembled during the Bridges conference in Enschede, the Netherlands. All information is secure inside of Rainbow.
