Incremental pattern - distance and scale

Hi,

i got inspired by tripleGworkshop's Christmas trees and wanted to try to model something similar in F360.
Its a fairly simple shape (for example we could make it a sphere for simplicity)
which is then simply:
- patterned around a circle

- the whole group moved diagonally and scaled down
- the proccess repeats and it always takes the last copy and incrementally scales them down to infinity for as many copies as are made

The whole process took maybe 5 minutes in tinkercad and while being cheesy, it gets it done.


Sadly i did not figure out how to make this - except maybe painstakingly making each object by hand.

 

  • My first idea was a pattern along path but that only makes equal spacing of same sized objects - even if you were to scale them individually later the equal spacing would ruin it.
  • No "repeat" command would remember the move distances and even if, fusion does not play nice if one decides to later change any of it
  • I did not figure out a possible way to use parameters in a pattern, which would maybe tell me the number of the created instance and allow me to add a changing variable.. that would be the simplest way to make this i think.
  • I found some tutorials with objects joined to a spiral path, which would sort of help but since the distance and size both scale down it still required a lot of hand work and defining each object.
  • Sweep is able to scale if its given paths to follow but that's also not quite what i am looking for.
  • One could surely design some of it in a sketch and define for example the sphere sizes by linking the dimensions to each other with a parametric increment but that only helps a little and still needs a lot of work

 

Do you have any ideas how one could make it?

Are there perhaps any mods that would make this easier?

Thank you.

They made a tutorial for the base of it, done without scaling, to create a vase but otherwise its the same workflow:
