Detailed Steam Locomotive 3D Model -- 2

I have a full set of 2-D drawings for a classic steam locomotive and now need them translated into a precise, production-ready 3-D model in AutoCAD. The file will be used directly for manufacturing individual components, so accuracy and part separation are critical.

Scope
• Create a complete high-detail 3-D assembly of the locomotive, including chassis, boiler, wheels, drive rods, cab, and all visible fittings.
• Model each component as its own part file, organised in logical sub-assemblies so machinists can pull dimensions quickly.
• Maintain correct tolerances and clearances based on the supplied drawings; ask whenever a dimension is missing or ambiguous.
• Where drawings lack internal features, reference typical steam-era construction standards to keep the design authentic.

Deliverables
1. Native AutoCAD 3-D files for every individual part and the master assembly.
2. Step/IGES export of the full assembly.
3. A brief part list (spreadsheet) that cross-references drawing numbers to file names.

Acceptance
The model should open error-free in AutoCAD 2024, measure within ±0.1 mm of the provided dimensions, and allow a full exploded view without interference.

If you have hands-on experience modelling mechanical assemblies for manufacturing and you’re comfortable working from historical drawings, I look forward to collaborating with you.
