Hi Warren,

1) just bevel you edges in MoI and they will then come in fine in MODO.

I also don't understand why you want to subdivide a perfect NURBS mesh from MoI, which is usually not necessary?

I have Groboto also and never subdivided a Groboto mesh further in MODO, because i can set the density of the quad mesh in Groboto. Maybe it's a different story if you like to use the MODO/Groboto toolkit to enhance your Groboto mesh further in MODO.

IMHO subdividing a low-poly quad mesh in MODO should require that you build your low-poly quad mesh in MODO or any other subdivision surface modeler and not necessarily in MoI or any other NURBS modeler for that matter.
