Hi all,
Noobie.

I Created a curve on a sweep where the curve is perpendicular to the ground. I setup a reference Transform at (0,0,1) from the points in the sweep so the normals will face outwards in the world (Z). I did this so I can extrude the faces and adjust the width of the sweep so this way it extends out without any twisting in the sweep.
It works well but my issue is when I input a different curve where the curve is laying on the ground (the typical way). If I create a simple circle of curve points for example. Since it uses the same reference all the normals point at (0,0,1) in the world again. Therefore the back side of the “circle” curve points outward properly but all the points do so I get twisted geometry because all the normals point the same way (toward the reference transform).

Basically,
I need to learn how to control the directions of the normals based on where in the world the curve points lie. If not that then at least have all the face normal directions face outward locally.

Thanks for any assist

This thread has some discussion on the topic of adding normals to curves for orientation purposes.
