HFOIL
HFOIL is Hendoi’s Windows product for aerospace aircraft geometry: mission templates, one-click generator, parametric full-aircraft rebuild, airfoil library, Geometry Studio, wing/fuselage/tail/engine/gear builders, assembly, 2D drawings, multi-format export, and HEN-AI design assist. Domain-specific aeronautical CAD — not general mechanical CAD. No mesh, polars, or CFD inside HFOIL. Export STEP/STL → HENMESH; aerospace CFD → HENFLOW.
Generate a full airframe from templates or mission inputs, edit the parametric model, assemble and draw, then export clean STEP/STL — mesh and CFD stay in HENMESH and HENFLOW.
Signature capabilities
HFOIL builds complete airframes for aircraft, UAV/eVTOL, and aero labs: mission templates, one-click generator, parametric AerospaceModel rebuild, component presets, assembly, and 2D drawings. Not mechanical part modelling.
Start from GA, jet, UAV, VTOL, fighter, regional, or sounding-rocket style templates — or generate an airframe from passengers, Mach, range, and MTOW in one click.
Edit span, sweep, taper, twist, dihedral, fuselage length/diameter, tail layout, engines, gear, rotor, and prop — rebuild lofted CAD and orthographic views from the same model.
Airfoil Library and Geometry Studio prepare root/tip sections; Wing CAD plus fuselage/tail/engine/gear shells and control-surface regions feed the aircraft tree.
Loft, extrude, sweep, revolve, boolean, mirror, mid-plane, section clip, offset, fillet, shell, and pattern. Export STEP, IGES, STL, OBJ, glTF, DXF, drawing DXF, DAT, and PDF geometry packages.
design_assistant, cad_assistant, airfoil_assistant, aircraft_designer, and cad_debug modes apply geometry overlays — never mesh/y+/ClCd advice. Export STEP/STL → HENMESH → HENFLOW.

Full feature catalogue
Mapped from the live HFOIL native product — Templates through Export. Mesh prep in HENMESH; volume CFD in HENFLOW.
Typical workflow
Start from Welcome — new .hfoil project or open recent work. The home workbench opens on Aircraft geometry.
Pick a vehicle template or run the one-click generator from mission inputs (pax, Mach, range, MTOW).
Tune wing, fuselage, tail, engines, and gear in Aircraft properties — rebuild lofted CAD and inspect the tree.
Choose or fair library airfoils in Library / Geometry Studio, assign root/tip, refine planform in Wing.
Review the full configuration, update top/side/front views, rib/spar layouts, and drawing DXF.
Export STEP/STL (plus IGES, glTF, DXF, DAT as needed), then hand geometry to HENMESH and aerospace CFD to HENFLOW.
Who it serves
HFOIL is Hendoi’s native Windows desktop workbench for aerospace aircraft geometry CAD: mission templates, one-click aircraft generator, parametric full-aircraft rebuild, airfoil library, Geometry Studio, wing/fuselage/tail/engine/gear builders, assembly, 2D drawings, STEP/IGES/STL/OBJ/glTF/DXF/DAT/PDF export, and HEN-AI design assist — for education, research, and early aircraft or UAV programmes. Mesh prep is HENMESH; volume CFD is HENFLOW.

Straight answers about HFOIL aircraft geometry CAD, export formats, HENMESH/HENFLOW handoff, and licensing.
HFOIL is Hendoi’s native Windows desktop workbench for aerospace aircraft geometry CAD — mission templates, one-click generator, parametric full-aircraft rebuild, airfoil library, Geometry Studio, wing/fuselage/tail/engine/gear builders, assembly, 2D drawings, multi-format export, and HEN-AI design assist. It is not general mechanical CAD. Mesh preprocessing is HENMESH; volume CFD is HENFLOW.
No. HFOIL is CAD-only — aircraft geometry, assembly, drawings, and export. Aeronautical / aerospace volume CFD — Euler, RANS, high-lift, rotorcraft, rocket paths — lives in HENFLOW. Prepare meshes in HENMESH, then solve in HENFLOW.
No. HFOIL does not include panel methods, polar sweeps, VLM/LLT loading, batch ranking, or inverse design. Build and export geometry in HFOIL; run aerodynamic analysis in HENFLOW after mesh prep in HENMESH.
Yes. That is the primary workflow: templates or one-click generation, parametric AerospaceModel (wing, fuselage, tail, engines, gear), rebuild lofted CAD, assemble, draw, and export STEP/IGES/STL. Airfoil tools prepare sections for the airframe.
Typical chain: build and freeze aircraft geometry in HFOIL → export STEP/STL → prepare flight-condition meshes in HENMESH → run aerospace CFD campaigns in HENFLOW. Each product stays domain-specific to aeronautical / aerospace work.
Primary shipping platform is Windows (native C++ HendoiUI + HFoilCadNative). Cross-platform builds exist for Linux and macOS. Licensing for commercial, university, and academy seats is available worldwide via Contact.
