Does anyone know if there is an easy way to make a spline handle normal to a plane.

I can do this by making some construction lines.

However one would think you should be able to use a relation to make the handle normal to the plane.

Thoughts?

I usually make a 3d sketch with short construction lines that have a point on the surface and perpendicular relations. The spline is usually another 3d sketch. I can hide the construction line sketch when done. Spline tangent relations are not always reliable, they can get an offset and remain off tangent. This is fixed by suppressing the relation and reactivating the relation.
