Am trying to work out how to align my normals for a polyextrude using curves imported from illustrator via alembic export in C4D.

Seems like a basic thing to do but i can't get my head around it, have tried just adding @N attribute and setting it to run over points.

Looks like depending on the direction i've drawn the curves in illustrator dictates the direction of the extrude.

Is there any way to align them so the first point etc would be as such that the extrude happens along Z+ not some Z+ and some Z-

I know I could just tweak the sequence in the points in C4D, but have a lot of curves to amend!
