I am trying to draw a cross section of an airplane wing, which involves a bunch of coordinate points in a 2D plane, and a curved line passing over those points without any consistent radius. Is there any way to do that in DataCad? I have perused the curves menu to no avail. Bezier and B-spline neither work for this because you have no control over the curved line, just the points.
Looks like a job for 3D Contour:
