The prompt
Create a precise, fully dimensioned, parametric 3D CAD model of a DIY indoor cat tree with an enclosed cat house and three elevated platforms. **Overall dimensions:** - Maximum width: 750 mm - Maximum depth: 750 mm - Total height: approximately 1600 mm - Rectangular construction with straight edges and flat wooden panels. **Construction:** 1. A stable square base, 750 × 750 mm, made from 18 mm particleboard. 2. An enclosed rectangular cat house at the bottom, approximately 500 × 450 × 400 mm, with a circular entrance approximately 200 mm in diameter. 3. Exactly three elevated platforms at approximately 650 mm, 1100 mm, and 1580 mm above the floor. 4. Platforms should be staggered horizontally so a cat can comfortably jump or climb between them. 5. Each platform should provide a usable resting area, approximately 350–450 mm wide. 6. Multiple vertical cylindrical wooden scratching posts, approximately 90–110 mm in diameter, connected to the base, platforms and supporting structure. 7. Scratching posts will be wrapped with sisal rope after assembly. Model the wooden cores only. 8. All flat wooden surfaces will be covered with upholstery fabric after manufacturing. Do not model the fabric. 9. Include appropriate structural supports and secure mechanical connections between the posts and boards. 10. Design the top platform to be suitable for a cat to sleep comfortably. **Manufacturing requirements:** - This is a real DIY furniture project, NOT a decorative sculpture or 3D-printing project. - Use simple flat rectangular panels that can be cut from standard particleboard sheets. - Use commercially available cylindrical wooden posts or tubes. - Avoid complex curved surfaces, organic shapes, and unnecessary decoration. - Model the individual physical components as separate parts. - Include exact dimensions, panel thicknesses, post lengths and hole locations. - Make the design suitable for assembly using screws, threaded inserts and appropriate furniture connectors. - Include a practical assembly concept and a bill of materials. - Clearly distinguish between the base, cat house panels, platforms and scratching posts. - Keep the entire structure inside the 750 × 750 mm footprint. - Prioritize stability, ease of cleaning, safe cat movement, and realistic manufacturing. **Deliverables:** 1. A complete editable parametric 3D CAD model. 2. An assembled view of the complete cat tree. 3. An exploded assembly view if supported. 4. A complete dimensioned parts list. 5. A cutting list for all particleboard panels. 6. A list of wooden scratching posts with required lengths and diameters. Use millimeters for all measurements. If any design details are unspecified, make practical assumptions and document them. Do not claim structural safety has been validated without an engineering check.
