Sorry, separate point: >Mesh formats like stl cannot represent a circle by its position and radius, while a parametric format like step can. This is where I think the Geometry nodes can help. A node (function) can be used to represent the circle with inputs and outputs set or changed as required.[0] I have not fully explored this space though and so my "hopes and dreams" may well be as useful as thoughts and prayers...
