Dynamic double circle

[Anonymous]

Hello,

I'm trying to create double circle where i can stretch to bigger or smaller outer circle, but same time my inner circle should maintain same distance from out circle. In other words radius of inner should be (outer radius)-constant. What happens with linear scale action that distance between circles get bigger when i scale.

In picture desired bigger circle is at bottom and not desired at top. I have tried with arcs, with increment list, adding block table and trying to add variables in there, constrains but nothing seem to be working well with circles.

Welcome to the Forums

Here you go. The block involves two scale actions and a linear stretch.

Hello,

Amazing, thank you so much. This is exactly what I was trying to do 🙂
