The prompt
Act as a professional mechanical CAD engineer and an expert in AutoCAD 2D drafting. I am uploading an engineering drawing from my B.Tech Mechanical Engineering CAD assignment. YOUR TASK: Analyze the uploaded engineering drawing carefully and recreate it as an accurate, editable 2D AutoCAD drawing. IMPORTANT REQUIREMENTS: 1. GEOMETRY * Recreate the drawing exactly as shown in the reference image. * Use the given dimensions, radii, diameters, angles, and geometric relationships. * Maintain correct proportions and geometric accuracy. * Use actual CAD geometry, not a raster image or a visual approximation. * Use LINE, CIRCLE, ARC, POLYLINE, SPLINE, and other appropriate CAD entities. * Ensure all lines and curves connect properly. * Use tangent arcs wherever required. * Do not introduce unnecessary geometry. 2. DIMENSIONS * Use the dimensions provided in the reference drawing. * Assume all linear dimensions are in millimeters unless specified otherwise. * Do not invent missing dimensions. * If a dimension is unclear, identify it and ask for clarification. * Maintain the original geometric relationships. 3. ENGINEERING DRAFTING * Use proper engineering drawing conventions. * Create separate layers for: * Object lines * Centerlines * Hidden lines * Dimensions * Construction geometry * Use appropriate lineweights and linetypes. * Add centerlines to circles, holes, and symmetrical features. * Include dimensions and annotations where required. 4. CAD FILE OUTPUT * Generate an actual editable DXF file compatible with AutoCAD. * Use a standard DXF format supported by AutoCAD. * Set drawing units to millimeters. * Ensure the drawing opens correctly in AutoCAD. * Do not output a PNG, JPG, SVG, or PDF as a substitute for the CAD file. 5. VALIDATION * Check that the generated geometry matches the reference drawing. * Verify all dimensions. * Ensure circles, arcs, and lines are correctly positioned. * Ensure the drawing is not distorted. * Provide a preview of the final drawing. FINAL OUTPUT: Generate the actual downloadable .DXF file. If possible, also provide: * A DWG-compatible version. * A dimensioned PDF. * A preview image. * A brief explanation of the geometry used. If you cannot directly generate a DXF file, generate a complete Python script using the ezdxf library that creates the drawing automatically.
