Golden Ratio & Fibonacci Sequence: Part 1

The Golden Ratio in Revit?
      Never!
Fibonacci Sequence in Revit?
      Impossible!
Parametric too?
      No way!

To close off 2014's blog entries, I thought it would be a good idea to prove that the creation of the Golden Ratio and respective Fibonacci sequence in Revit is indeed possible. The creation and manipulation thereof will be much easier using a program such as Project Dynamo, but the half the fun is figuring out how Revit can natively achieve this.

In a nutshell: Separate mass families were created (up to the 19th) which were nested into the "Master" mass family. Each nested family needs to have separate reference planes and separate dimension labels in order to work. Each nested family needs to be aligned and locked to the previous nested family (in sequence) to retain its position. Each nested family needs its own visibility parameter to control the extent of the spiral. I have drawn a continuous start-end-radius arc, so as to create a continuous sweep. Confused yet?






The second part of this blog entry will focus on the creation of the parametric geometry.

May you have a festive and safe holiday season, and rest enough to tackle 2015 completely, well, revit-alized.
