the data points are on z=0,1 and 2
that I wanna make a 3D surface graph and use the numeric controller to change the cross section between the z plane and the surface graph....so that if I putted z=1.5 the output will be the points of the cross section.
Starting atpost #7 of this thread I start a tutorial exaplaining how to use the 3d Graph to plot multiple curves and surfaces.
If you want your final image to look like an air foil your are going to have to present your data such that adjoining points in your surface are adjacent in the data set. THis thread shows a quick hack of a a car rendered in 3d.
If you want it all to be one color you will have to set teh color mapping to none.
Idividual ribs of the wing can be added as sepearte plots to over-lay the surface.
