VB script diagrid01

Testing Visual Basic script in rhino grasshopper.

"Diagrid (a portmanteau of diagonal grid) is a design for constructing large buildings with steel that creates triangular structures with diagonal support beams. It requires less structural steel than a conventional steel frame. Hearst Tower reportedly uses 21 percent less steel than a standard design. The Diagrid also obviates the need for large corner columns and provides a better distribution of load in the case of a compromised building. Another building designed by Sir Norman Foster, 30 St Mary Axe, known as "the Gherkin", also makes use of this structural system."via Wikipedia
