I got a question recently about how to associatively drive a spline in NX from data in a spreadsheet. We don't have an OOTB feature to do this, but thinking about it a little bit, I realized that Algorithmic Modeling could handle this nicely. This video walks through how to build a new NX Feature that will read point coordinate data from a CSV file, and then build an associative spline curve through that point data. The CSV file can be any length, as you'll see. I hope you find this useful!

By the way... Huge thanks here to two websites that freely offer point data files for thousands of airfoil definitions:

As described in the video, I did a little bit of manipulation of these files to put them into a consistent format for my purposes, but that was minor, easy stuff. Again, huge thanks to Professor Michael Selig at the University of Illinois and to the anonymous folks behind airfoiltools.com!
