Why Airfoil Digitizer is Unique

Airfoil Digitizer is not just another digitizing tool — it's purpose-built for aerodynamic design and analysis. Here’s why it stands apart:

• 🔬 Specialized for Airfoil Work: Airfoil Digitizer is designed specifically to extract airfoil and wing section coordinates from plots, drawings, and images — not just any generic curves.
• 📐 Accurate Coordinate Extraction: Optimized for leading edges, trailing edges, and smooth curvature — ensuring high-fidelity data for your analysis and designs.
• 🚀 Direct Workflow Integration: Seamlessly create coordinate files ready for CFD, CAD, analysis software, or manufacturing processes — no tedious data cleanup needed.
• 🎯 Made for Engineers & Designers: Ideal for aerospace engineers, UAV designers, hobbyists, students, researchers, and wind turbine developers.
• ⚙️ Fast & Easy to Use: User-friendly interface allows you to go from scanned image to accurate digital coordinates in just minutes.

Airfoil Digitizer is a software package for extracting airfoil data files from images. The software accepts images in the jpg, gif, bmp, png and tiff formats. Airfoil data is exported as AutoCAD DXF files (line entities), UIUC airfoil database format and Hanley Innovations VisualFoil Format.

Advantages of Airfoil Digitizer

• Scan reports, text books and journals and use Airfoil Digitizer to extract the airfoil coordinates from the illustrations.
• Get the coordinates of airfoils on from pictures on websites
• Take screen pictures of your CAD drawings and easily convert them to airfoil coordinates in ASCI format
