Michael,

You're right. i just think the even spacing of isoparms make them useful for additional geometry to be put in place. Being able to extract isoparms as curves would be a great addition though...

On the same note, I have another question since i'm really just learning about surfacing, if you can extract the isoparms as brand new curves and then network them, would you end up with the same surface or would there be a slight difference? I guess i'm asking because sometimes i prefer to see the wire frame and sometimes that affects my modeling approach. I simply don't know enough to understand the subtleties. :)

Any videos or links would be very helpful

Thanks again for the quick response.
