Thats really cool that MoI does something like this well that it seems every other fillet'r has issues with. The result I showed is from Delcams Powershape using the Parasolids kernel, Which is more of a mid range modeler like solid edge or solidworks, though it still gives a bunch of fillet options. I could get it to section up in many different ways, not just that "pole position" result, but they all did the bunching. None did what MoI's does.

Maybe Parasolids needs to see this example to incorporate...LOL
