Making undeformable circles?

Hello,



This picture shows a screenshot of two circles made in Rhino. The left one is deformable and has much more points then the right one which is not deformable (which is a true circle and not only a NURBS approximation). You can make the left one in MoI too, but not the right, can't you? If not, why? It's even not possible to import those circle from Rhino into MoI.
