Creating a circle of pins of descending height

[Smokeys]

I am creating a set of pins that are of descending height.   It would be neat (and I know it can be done) to create this as a formula where I can say I want each pin .1 shorter than the rest, and F360 computes it all for me.

Attached is a sample that pretty much shows exactly what I am talking about.

Hi @Smokeys,

Thank you for posting! I am using the "Change Parameter" in the screencast below. I noticed after recording the Screencast that you can also use the names of the dimension in the feature for Expressions. I hope this information helps!
