How to correct curve normal?

Question

I'm trying to set up a curve to curve contact but it keeps failing because Adams insists on putting the normal of my spline in some nonsensical direction. I've been trying to follow this help article which suggests changing the working grid but it doesn't seem to have any impact on the normal direction:

Normal vector of curve in curve-to-curve contact (hexagon.com)

Has anyone had success adjusting the curve normal direction in Adams 2022.2 (preferably through command language so I don't have to manually do this every time the curve profile changes)?

The problem is that your bspline is defined in the YZ-plane of the spline reference marker. Defining this in the XY-plane will likely solve your problem. See the attached.

I simply reordered the columns of the matrix so that the matrix points are defined in the XY-plane and the Z-column is zero. And then I rotated the spline reference marker.
