i cant quite understand the gh def from the photo. there are two methods i can think of trying:

1. doesnt the loft have an option for closed loft in it? you just need to choose that, or maybe its in a 'loft options' tool.

2. from the list of lines that you are lofts - use a list function to find the first in the list. - add the single line back into the original list at the end.

so you kind of go from 1,2,3,4,5 to 1,2,3,4,5,1

sorry i couldnt be more specific im on my mac, no access to gh
