The prompt
Act as a professional mechanical design engineer specializing in small electric vehicles and SolidWorks CAD. I want to design a compact, single-seat electric car as a graduation project. Create a dimensionally accurate, editable 3D CAD assembly suitable for further engineering work in SolidWorks. **Overall vehicle dimensions:** - Length: 1000 mm - Width: 800 mm - Single driver only **Chassis and frame:** - Rectangular welded steel square-tube chassis. - Use a simple, lightweight frame that is easy to manufacture. - Include cross-members, motor mounting brackets, seat supports, battery supports, and mounting points for the steering system. - Keep all dimensions editable. **Wheels and motors:** - Four wheels in total. - Two hoverboard hub motors installed at the rear, one on each rear wheel. - Two conventional non-motorized front wheels with a mechanical steering system. - Keep the rear hub motors close to their original hoverboard dimensions; do not enlarge them unrealistically. - Provide suitable mounting brackets and realistic wheel clearances. **Driver and controls:** - One driver's seat with adequate support. - A steering wheel and front steering linkage. - An accelerator pedal. - A separate brake pedal. - A reverse control. - A dashboard showing speed and battery percentage. **Electrical components:** - A battery compartment designed for a 36 V battery system, subject to verification of the actual battery specifications. - Space for the hoverboard motor controllers and the main control electronics. - Front headlights. - A solar panel mounted on the roof as an auxiliary charging system. **Body and roof:** - Simple, lightweight body panels. - A removable or accessible top cover. - A roof structure supporting the solar panel. - Easy access to the battery, controllers, and motors for maintenance. **CAD requirements:** - Create separate components for the chassis, wheels, motors, steering, seat, body panels, roof, battery enclosure, and brackets. - Assemble the components into one complete 3D vehicle model. - Use millimeters for all dimensions. - Avoid overlapping parts and unrealistic component sizes. - Provide orthographic views, an isometric view, and dimensioned engineering drawings. - Export the assembly in STEP format and provide native SolidWorks files (.SLDASM and .SLDPRT) if supported. Start by generating the chassis and wheel layout first. Then build the remaining components around the actual dimensions. If any critical dimensions are missing, ask me for them instead of guessing. This is a preliminary design concept. Do not claim the vehicle is safe to drive until the chassis, steering, brakes, stability, and load capacity have been professionally verified.
