Could someone kindly describe how to import naca airfoil coordinates (Spline) into ViaCAD Pro?

Hi, needs to be saved as a .spl file i think. And in the .spl file the first line needs to read SPLINE and something else. There is some info somewhere on it.

It's a coordinate list. The coordinate list is headed "THROUGHSPLINE", then "THROUGHTOLERANCE", then "0.00001"
No commas in the coordinates, use a space as delimiter, add a "0.0" third, Z coordinate, give the text file a name. Import the file using import|spline. Tim's "Tricks & Tips" .pdf notes that the data doesn't do anything with the slope of the start and end of the curve, so the curve doesn't have continuity through them. But I was surprised to see that even though the start and end vertices had the same coordinates, VCP didn't make the endpoints coincident. I don't know what's going on there, an error on my part, that particular airfoil (mh200 if anyone cares) and I haven't had time to pursue it yet.
