Hot use the Isoparametric curve node
Hello today I was trying to use the isoparametric curve node and it keeps giving me an error, "computation result is empty." I was wondering if anyone else has run into this issue or might have a solution to why this doesn't work as I am trying to feed into it a mesh that was made buy a curve and a sweet note. From what I've understood there must be some way to highlight or designate the mesh has a target but I haven't been able to understand how, any help would be appreciated thank you so much in advance advance.
