Following our discussion, I have managed to build a very simple example to simulate a fitting circles or spheres in this case (just switched mode for for visibility). The task is that the curves touch a defined boundary on a surface - speaker mesh, that has to allow a percentage of air through. I think it best to build the boundary in CATIA V6 then split this to create the boundary and use this as input. That will be my next task. Could I use a law or function editor to control the positions less randomly?
