Is there a way to randomly instance parts over a surface?

I want to scatter spheres over a freeform surface. Is there a featurescript to do this?

    Hi @ron_moreland

    We intentionally don't provide true randomness in FeatureScript.  If we did, your spheres would regenerate in a different place every time and lots of downstream features would probably break due to references changing in unpredictable ways.

    Instead, you can use this function that Ilya wrote:
    https://forum.onshape.com/discussion/4086/pseudo-random-number-generator

    It takes a "seed" that you could take as a parameter into your feature.  That way, when you change the seed, the spheres change position, but every time it regenerates with the same seed, it regenerates the same way.
