Yes I tried that, but to get a single smooth subd without creases, I need to perform a mesh join operation followed by a mesh weld operation. Unfortunately that only works when the subd has no ngons, since these get converted to triangles by the mesh weld operation.
So another way to put this wish on the list is to ask for mesh welding that doesn’t convert ngons to triangles.
In my case and I think in many cases you will see that a radial symmetry often has a base element that has axial symmetry, like most wheels on the market today.
So what I need is the ability to add axial and radial symmetry to a model both at the same time. I think however having this in gh is easier to work with. Because then I can choose to switch between the base model and the full model quickly.
