circular pattern with random direction possible?

[jdholbrook33]

I'm wanting to make a circular pattern of stars and have each star pointing in a random direction.

Is this possible to do without editing each star?

My plan is to have at least 6 circles of ever increasing diameter and increasing size of stars. Each with stars facing a random direction.

Extra points if it's possible to automatically create the the circles and have the stars increase in size by some non-linear factor.

Thanks for looking.

Hey @jdholbrook33,

I cannot think of a way to automate the rotation and size increase for each star, but if you create one star and pattern the sketch around, then you can manually edit every pattern instance which shouldn't be too painful. You could even use User Parameters if you wanted to scaling factors to be exactly logarithmic. Check out the below screencast for a quick start to the issue!

Let me know if you have any other questions!

What you are looking for is more a generative approach that works like this

make a circular pattern of circles

collect the center points for each circle

place onto each center point a star

The position function has a z axis random rotation function added.

this is somewhat in words expressed how this would work in Grasshopper or such

but this is not how a parametric modeler like fusion works
