Not a problem. The UUIC collection, which can be downloaded as a single ZIP file, contains more airfoils than I could possibly use. I consider the coordinates like a library that you go to when you need something. I did input the SOF, or whatever they really are, coordinates into Excel and played around with the graphing capabilities. It wasn't good for the nose, and scaling up and down is a real chore. I also drew profiles in my CAD program by entering the points and then connecting the dots with Bezier curve lines. That is labor intensive, but allows for total rescaling as needed. That was before I found airfoils posted in DWG and DXF format.
