Loft not connection to two curves

[Lizo (Liza)]

thanks for any help

I guess you need to flip the Matrix…because loft works only for a list …but you have no list in your tree

Use Merge component (and probably a right clic > Simplify on all inputs)
Please post a GH file with internalized geometry if you need further assistance !
