Quick question on 'golden ratio'

[lara.nazarian]

Hello,

What is the correct grid for 'golden ratio', circular or in squares?

I've already made the spiral with model lines.

Thanks in advance!

A series of Formula-Driven Parameters will get you there...

Useful link, thank you! But this wasn't really my question. I'll try to explain better with some pictures.

You see, I've already made the spiral. Now to continue my project, I have to use gridlines. I've been trying to figure out which one works best, but there are quite some viarities. I've made two quick examples of what I mean with 'square' grids or 'circular' grids.

Anyone with experience?

Sorry, but I don't understand what you're doing.  What's the purpose of the Grid?  What are you planning and documenting overall?

The golden ratio is to get linear dimensions according to the ratio.  So, you just need linear, not radial or circular , grid lines.

Take a square and multiple one side by 1.618 to get a new shape: a rectangle with harmonious proportions. If you lay the square over the rectangle, the relationship between the two shapes will give you the Golden Ratio.

Honestly, I am delighted at the responses on this thread I kinda expected "Revit questions only 😡"

@lara.nazarian I dont think there is a "correct" way to do anything with the golden ratio. Its what you make of it and how far you want to take it. You can make your own ratio or use other shwanky things such as the "flower of life" Dodecahedron, etc....

 The golden ratio describes predictable patterns on everything from atoms to huge stars in the sky.

 The ratio is derived from something called the Fibonacci sequence

The next numbers in the Fibonacci sequence, for instance, are 1,2,3, and 5.

                    0
                    1
                    1 (0 1)
                    2 (1 1)
                    3 (2 1)
                    5 (3 2)

The ratios of sequential Fibonacci numbers (2/1, 3/2, 5/3, etc.) approach the golden ratio. In fact, the higher the Fibonacci numbers, the closer their relationship is to 1.618.

                    2/1 = 2
                    3/2 = 1.5
                    5/3 = 1.66666666 . . .

so the ratio is not fixed.. its more of a sequence.. 

hope this helps a bit.

cheers.
