Hi,

How can I ensure that vlax-curve-getClosestPointToProjection returns the closest point in every case? I suspect that the curve is merging in the projected plane and therefore it does not always return the closest point in the desired direction.

Alternatively, I could probably use vla-IntersectWith method with a line object and find the closest point, but I'm using grread where vlax-curve-getClosestPointToProjection will be more appropriate, I don't have to create and delete line objects in while loop.
