A clean, technically precise studio shot of a commercial vehicle chassis on an alignment rig, with bright white laser measurement lines running along frame rails and mounting points. Two engineers in high-visibility vests are kneeling with tablets and measuring tools, checking dimensions for a truck body modification project. On a nearby rolling cart, printed CAD drawings and vehicle modification approval forms for a box truck and minibus are visible. Neutral, shadow-free LED lighting, slightly low three-quarter angle down the length of the chassis, emphasizing accuracy, planning, and vehicle project engineering.
