In the attached grasshopper file, I am running into a problem with the loft feature. I have two sets of curves, “side curves” and “top curves”. I want to loft these curves together to create ribbing. The top curves can be lofted successfully, however the side curves encounter an unidentified error “Loft could not be constructed”. Both sets of curves were generated and sorted using the same components. I have checked the items below but I am not sure why one set of curves (top curves) works but side curves do not. Can anyone lend some insight?
- curves are in the correct order: for side curves they are sorted in the x direction.
- all curves are closed
- same type of curve (sometimes there are errors when you loft a line-like curve to something else, but this is not the case)
