need to create an image: A flat, geometric technical illustration of a VAV (variable air volume) terminal box, shown as a clean cutaway diagram of the rectangular sheet-metal casing only: a round or oval inlet duct connection at one end, an internal damper blade on a shaft with an actuator mounted on the casing exterior, and a velocity/airflow sensor pickup just downstream of the damper. Discharge side shows a short duct stub only — no grille, no diffuser, no ceiling tile in contact with the box. The box floats in an open ceiling plenum space, with a technician's hand holding a separate handheld digital airflow meter near the discharge duct stub (not touching or mounted to the box). Background: a faint architectural wireframe of a glass skyscraper interior, straight edges, drafting-line style, in Aero Dark Blue ( #043659) with light wireframe strokes. Overlay 3–4 flat hexagon shapes in Aero Light Blue ( #00A9E0), Hill Blue ( #005EB8), and Aero Orange ( #ED7D31), some solid-filled, some outlined, clustered in a corner. Aero Orange highlights the sensor or a small out-of-range indicator on a simple line graph in the corner. Flat, solid color fills only — no gradients, no glow, no drop shadows, no photorealism. Do not depict a diffuser, grille, or register attached to or built into the VAV box itself. Clean vector/illustration style, high contrast, no text, no logos.
