Airplane CAD Blocks

Five aircraft seen from above, each a single insert with wings, tailplane and engine outlines closed so a hatch will take inside them. Four are compact enough for a general aviation apron; the fifth is a long airliner, roughly three times the span of the others, which suits a terminal or hangar drawing. Airport plans are drawn at 1:500 or 1:1000, so insert the aircraft, scale it to the wingspan your brief names, and plot it grey — the stand markings and clearances are the subject, not the plane.

Questions

Are these plane CAD blocks free?

Yes — free to download and use in personal and commercial projects, with no account and no attribution.

DWG or DXF — which should I download?

DWG if your CAD opens it natively; DXF for everything else — cutters, CAM and open-source CAD. Both carry the same geometry and layers.
