The prompt
Create a parametric 3D CAD solid model of a compact two-zone welded steel chassis frame using 30x30x2mm square hollow structural steel tubing (RHS): 1. Outer bounding box dimensions: Width X = 650mm, Depth Y = 500mm, Height Z = 850mm. 2. Vertical division (Thermal Firewall Bulkhead): At X = 320mm, create a vertical dividing frame from Z = 0 to Z = 850mm holding a double-layer 1.5mm galvanized steel firewall sheet with a 15mm ventilated air-gap slot between layers to thermally isolate the left Hot Zone (X: 0 to 320mm) from the right Cold Power Zone (X: 320 to 650mm). 3. Left Hot Zone shelves: Lower slide-rail mounting ledge at Z = 80mm for the fuel drawer; heavy-duty circular boiler support ring (inner diameter 282mm, 4mm thick steel plate) at Z = 380mm; top cast-iron stove cutout opening (280x280mm) at Z = 850mm. 4. Right Cold Zone shelves: Bottom battery tray at Z = 60mm (310x460mm); middle hinge-mount crossbar at Z = 600mm with four M8 mounting holes spaced at 380mm for the oscillating condenser hinge shaft; top vibration-isolated mounting bracket at Z = 650mm with three M8 bosses matching Denso ES18C mounting ears. 5. Add four 45x45x4mm corner gusset plates at base corners with 10mm anchor bolt holes. Export as watertight STEP solid.
