I’m actually working on a project where I need to make the model of a very accurate terrain. I have horizontal and vertical profiles of the terrain every 1 m. From these curves, I’d like to generate a surface (not mesh) using the Network Surface command. But everytime I use this command, Rhino tells me “unable to sort curves”. I’ve tried on Grasshopper too but the result is always “null”.
I’ve checked solutions from other similar topics to see if the curves are self intersecting, closed, overlapping, but it’s not the case. So I am kinda lost here.
Is it possible for someone to give me more information or any solution about this problem please ? It would be very helpful.
Thank you in advance.
