The manufacturer lists 46.53 ft / 14.18 m span and 42.97 ft / 13.09 m length. The top view defines the wing, fuselage, nacelle and horizontal-tail proportions. Smooth native SVG curves are manually traced over that drawing, reflected about the centreline and uniformly scaled. Original 690 configuration without later-model winglets or extended wingtips. Slender edge-on propeller bars are added at the propeller stations. Cockpit glazing and restrained nacelle/control-surface details are transparent cuts. Checked with a reference overlay.
Decorative identification artwork, not an engineering drawing.
