A clean 3D view reduces analysis surprises. HFOIL’s CAD viewport is there so you can inspect geometry with the same care you give to coefficients.
Orbit with intent
Check leading-edge smoothness, trailing-edge closure, and tip fairings from multiple angles. Defects that hide in top view often appear in side or isometric views.
Switch display modes
Wireframe helps with topology and intersections. Shaded / PBR-style views help with surface continuity. Use both before trusting a polar.
Import checklist
When bringing CAD or coordinate data in, verify scale (meters vs millimeters), unit consistency, and that multi-element slots have sensible gaps.
Engineering takeaway
Airfoil selection is a trade among lift, drag, stall gentleness, and pitching moment. Document Reynolds number, Mach assumptions, and geometry provenance whenever you share polars with a team.
How HFOIL helps you act
Use HFOIL on Windows to iterate sections, generate polars, move into wing loading, and prepare review-ready plots. For licensing in any country, use Contact Us or email support@hendoi.com.

Students: treat each case as a lab notebook entry. Companies: shortlist two or three sections before freezing CAD. Academies: assign compare-and-justify exercises using batch plots.
