Parametric Golden Section & Fibonacci Guides for Fun.

[Jeffrey McGrew]

Heya!

Here are two quick families I made over lunch that I thought of on the bus. I have no idea to whom they would be useful to, unless someone is using Revit to lay out Egyptian temples or Neo-Classical Greek Plaster details; but anyways- here are two 'overlays', one for the Golden Section, the other for the Fibonacci number series.

They are parametric, and made up of 2D lines within a generic model family. You can drop one into your project, tell it the 'base' length, and it will auto-calc (and draw) 2D guidelines for the next few steps up in the series. Then you can snap anything you are drawing/modeling to it. Bam! Instant Greek Temple plan! ;)

Anyways, have fun.

Jeff,

That's really funny! The Golden Section was one of the first familes I made when I started at Revit. Wow, this was back before they were even called .rfa files :roll: ...

Note that you don't need to use formulas for this at all. You can solve the problem geometrically using just contraints instead of algebraically with formulas. I'll post my family if I can find it.

Using instance parameters, you can actually lock golden section modules together and create a spiral that is stretchable.

I'm still hoping to design a fully parametric Palladian villa at some point!

When I was studying architectural computing at Sydney Uni years ago, one of the gurus had an AI pilot programme that could design Palladian villas automatically, given basic input. This was waaaay before parametrics.
We all thought it was going to change the world (of architecture ). Don't know what became of it.

So, yes, get to it Matt.

While you have so much free time shouldn't you be sticking to towers, Tatlin?

OK who is going to give it a try in Revit? Peter?

Nice photo Robert. I notice Tatlin said he had a trick for interlocking spirals so maybe he should take this on not me.

I wouldn't know where to begin.

heh, you guys are welcome to try - there is an internal logic to the design that might make it easier. Did you know the pieces were supposed to rotate? I'll take a crack at his 3rd international tower after I find time to parameterize a palladian villa.

Tatlin is one of my idols. However, I think the most appropriate tower to build these days would be one from Ken Yeang.
