How do I use the RevSrf with FPatch and Unroll Brep?

Hi all,

I’m auto surfacing multiple closed curves joined together to then be auto unrolled. It’s all working apart from the UV direction is flipped the wrong way sometimes. It’d be nice if I could get the DIR arrows to populate the 3D GH too.

I can’t workout how to make the RevSrf work with what I’ve got. I’m sure it’s very simple but I’m quite novice at GH.

Can anyone help? Thanks.
