The prompt
If you’re using an AI text-to-CAD tool (such as Autodesk Forma, Finch3D, Hypar, or another AI CAD generator), you’ll get better results with structured, dimensional instructions rather than artistic descriptions. Text-to-CAD Prompt Project: Mixed-use Motorsport Lifestyle Complex Site Size: 2.5 acres (approximately 101 m × 100 m, rectangular site) Create a 2D CAD site plan with the following layout: * Main road along the north boundary. * One primary entrance centered on the north side with a separate service entrance on the northeast corner. * Front 25% of the site allocated for public functions. * Provide a parking lot for 60–80 cars with 6 m wide drive aisles, pedestrian walkways, landscaping islands, and designated motorcycle parking. * Place a two-story restaurant/café immediately south of the parking area. Building footprint approximately 30 m × 20 m. Orient the main glazed façade toward the go-kart track. Include an outdoor terrace facing the track. * Reserve space beside the restaurant for an auction plaza and display area for 6–10 vehicles. * Center 40% of the site dedicated to a Monaco-inspired go-kart circuit with: * Track width: 8 m * Start/finish straight adjacent to the restaurant * One tight hairpin * One fast chicane * Several medium-speed corners * One pit lane with pit building * Safety runoff and tire barriers * West side: Garage and workshop building approximately 20 m × 15 m with four service bays, detailing area, storage, and service access. * East/rear 20%: Animal care park with walking paths, lawns, trees, shelters, seating, and perimeter fencing. Separate this area from the track using a landscaped buffer of at least 10 m. * Provide pedestrian circulation connecting parking, restaurant, viewing areas, garage viewing windows, and animal park. * Separate all vehicle service routes from visitor pedestrian routes. * Include internal roads, drainage direction, lighting locations, landscape planting, and utilities. * Add north arrow, scale bar, dimensions, room labels, parking counts, and building names. * Use standard architectural CAD layers for buildings, roads, landscaping, parking, utilities, and annotations. Output: Professional 2D CAD site plan suitable for architectural development, with clean linework, accurate dimensions, and editable geometry.
