 Do you know a way to get this kind of square round fully parametric? (you can forget loft features: they don't create flat linking surfaces) A sweep will generate planar faces. You just need to add a straight line between the circle and the rectangle to use as sweep path. Could you share your round to square model? I'm curious about a couple of things. How did you create the fillets for the bends? And how did you manage to include a Part Cut inside a Body container? That should not be possible.
