If you download a coordinate file (.dat), follow these steps to turn it into a 3D model:
When you click "download," you will likely encounter several file types. Choosing the right one depends on your workflow. 1. .DAT and .TXT (Coordinate Files)
Extrude the sketch to create a constant wing, or use the "Loft" tool between two different airfoil sketches to create a tapered wing. Critical Checklists Before You Print or Mill
These are the "gold standard" for professional engineering. They provide high-fidelity geometric surfaces that are easy to manipulate, scale, and shell. 3. .STL and .OBJ (Mesh Files)
The industry standard for searching the NACA databases. It allows for direct exports of .dat and .csv files.
These contain raw X and Y coordinates. Most CAD programs (SolidWorks, Fusion 360, CATIA) cannot open these directly as 3D objects. You must import them as "Points via XYZ data" to create a spline. 2. .STEP and .IGES (Universal CAD)
The classic "flat-bottom" airfoil. It is incredibly easy to build and provides excellent lift at low speeds.
