Hello there! Saved developed in rhino surface to IGES, opened this IGES file in Rhino to proof and what I see is weird broken surface, tried to fix it with “rebuild edges” and it repairs the general shape but in the same time cut it in some odd way, please see the pic. Whats going on?
P.S for some reason I cant add tags like iges to topic, why? This is my first topic.
