I posted a grasshopper definition in the files that might be off some help triangularSPFM.wrm<http://grasshopper3d.googlegroups.com/web/triangularSPFM.wrm?hl=en&gda=RoQ3ZkQAAABldvTupClBBQRPKkY0ld_QN8dssvmabrhIjSP0uguWu-6PUXFii6ElEHmf_0EeVJJV6u9SiETdg0Q2ffAyHU-dzc4BZkLnSFWX59nr5BxGqA>
If you loft a surface from the perimeter curves of your floor plates you could then divide that surface up into a grid of points. Then take that list of points, and make a copy by shifting it by the # of horizontal divisions (either the U or V value) and add 1. Plug these two lists into a line segment and you'll get the diagonals in one direction. Then repeat with the appropriate shift for the other direction and the horizontals. You can then plug these lists of lines into a join component and get long continuous lines. Hope this helps.
