Classic Ming Table CNC Ready Files Crucial: Read & Understand Before Bidding You must thoroughly read all instructions and review both PDF plans before bidding. Your bid is a fixed price for all requirements: accurate 2D DXF and 3D STL/STEP files for every part, precisely matching all dimensions, features, and complex joinery. No additional payment will be approved for scope misunderstanding. To confirm understanding of this project's historical context, naturally integrate "Ming Dynasty Craft" into a sentence in your bid. By bidding, you agree to complete all tasks for your submitted price. Part 1: General Requirements CAD Software: Capable of accurate 2D extraction & 3D modeling. Units: Imperial (inches) only. All models MUST be 1:1 scale (real-world size). File Formats: 2D Outlines: .dxf (CNC ready for VCarve Pro). 3D Models: .stl or .step (CNC ready, watertight solids for VCarve Pro). Master Assembly: Optional (native CAD / single STL/STEP). Naming: Clear, descriptive (e.g., Leg_FR.dxf, Spandrel.stl). Accuracy: All dimensions, angles, curves, and joinery details must precisely match PDF plans. Part 2: 2D File Extraction (DXF) - CNC Ready Extract separate .dxf files for each unique wooden part. Review Plans: Use both PDF files. Extract Outlines: Trace outer perimeter, all internal cuts, holes, mortises, tenons, dovetails. EXCLUDE: dimensions, text, hidden lines, assembly lines. Focus only on physical shape. Scale: Ensure 1:1 scale. Verify with known dimensions (e.g., Leg length). Clean Geometry (CNC Ready): No overlapping/duplicate vectors. All closed shapes truly closed. Minimal, smooth nodes. Optimized for machining. Origin: Place bottom-left corner at (X=0, Y=0). Save: .dxf (e.g., AutoCAD 2000+ compatible). Examples (from plans): Legs, Long/Short Aprons, Spandrels, Top/Shelf Panels, Top/Shelf Frame parts, Top/Shelf Cross Braces. Part 3: 3D Model Creation (STL or STEP) - CNC Ready & 4th Axis Optimized Create separate 3D models for each unique wooden part. Model Features: Extrude: to correct thickness (from "Materials" list). Add All Joinery & Profiles: Mortises, tenons (mitered/through), dovetails (full blind mitered, shallow, sliding), rebates, specific profiles (e.g., spandrel radii, top/shelf frame edges), coped ends (shelf rails), angled cuts (leg mortises, apron ends). Precision is Key: Especially for glueless joints. Combine Features: Final, fully machined part. CNC Ready Solids & Scale: Watertight/Solid: No missing faces, inverted normals. Essential for CAM. Optimal STL Tessellation: High detail without excessive file size. Correct Orientation: Bottom surface flat on Z=0 plane. 1:1 Scale. 4th Axis Rotary (Legs): Model legs as single, complete 3D solids. All joinery features must be fully integrated and correctly oriented for potential rotary machining. Save: .stl or .step. Part 4: Final Check & Quality Assurance (QA) Before delivery, perform rigorous checks: Completeness: All parts (2D DXF & 3D STL/STEP)? Dimensions/Scale: All 1:1 scale, all dimensions match PDF? Features: All joinery, profiles, angles accurate in 3D models? Interference Check (Critical QA): Digital Assembly: Create full 3D assembly in CAD. Interference Analysis: Run clash detection. Resolve Issues: Zero interference in final assembly. Document Clearance: Report any intentional small clearances (e.g., for sliding joints). Part 5: Portfolio & Experience (Mandatory) Provide examples of previous CAD modeling work, specifically highlighting: Complex woodworking joinery (mortise & tenon, dovetails, angled components). 2D DXF & 3D STL/STEP files suitable for CNC fabrication. Experience/understanding of modeling parts for 4th axis rotary machining. Thank you for your careful work on this intricate and advanced woodworking project!
