Walls by Profile Facing Same Direction

[shelco18]

I am attempting to create walls by profile curves and I cannot get the finish faces to be consistent even though they all seem oriented correctly. I’m getting an exterior material on the interior in places where the walls should face outward. I have tried reversing the profile curve directions without any success. Is there a way to unify the direction they face?

The initial breps were surfaces that were taken from an extrusion.

Thanks for any help!

I know this is a bit late but there is a solution to this, but you will need some kind of guide (in this case your U-direction). Using the guide you can create a filter for Flipping the wall. Note that this will flip the wall unless your Wall Location Line is Center.

Its a bit of a workaround and it requires quite a few hopes… ¯_(ツ)_/¯
