Hi! I have a situation with ExtrudeCrv applied in Rhino5 (MAC&Win), that doesn't do it in Rhino4 (Win)
I need the comand to produce a surface, and in Rhino5 I obtained a Polisurface with 8 segments
I used rebuild on the orginal curve to obtain the singular surfface, but I don't know why I obtained those different results
Why I can't obtain the same result between Rhino4  and Rhino5?
Thanks for the attention
