How do I rotate around an ellipse?

I am attempting to creating a pendulum rack, where the spools move around the ellipse, but don’t rotate. I expect you understand, a center point through the spools would follow the track in the ellipse.

I greatly appreciate all you have done with Shapr3D over the years, it really is a wonderful tool.

I understand what you’re trying to model, but I don’t understand what exactly you’re asking.

Do you want to animate the model? Or do you want to attach spools so they follow the sketch movements? Or are you looking for some kind of constraints?
