see this post: [Is there a better way to constrain the outer circle to the inner circle?](https://discourse.shapr3d.com/t/is-there-a-better-way-to-constrain-the-outer-circle-to-the-inner-circle/28148)

I would like the ability to constrain the radii of two circles with a distance. This is easily possible in Fusion360 but is more complicated in Shapr

Yes, it is possible to do it by creating two tangential construction lines and constraining those but that adds a lot of overhead if you have a lot of circles you need to create
