When I create points from an equation then use the Spline to connect them together the spline seems to snap to the points, but if I zoom way in, none of the points are on the spline. I am trying to draw a normal to the curve (perpendicular) at each point. It seems that I cannot use the perpendicular constraint to a curve at a point, though there is a theoretical tangent I should be able to use at that point.
