Split the surface with multiple curve?

@Michal_Dengusiak The images in some of the posts above should now be readable. Also, here is the link to the old topic http://dynamobim.com/forums/topic/split-the-surface-with-multiple-curve/ If this doesn’t address your issue, I’d suggest you start a new topic. The responses will be better.
