Редактируемый паровоз в Blender по линейному рисунку

Build a detailed 3D steam locomotive with tender in Blender, reconstructed from a flat line drawing used as the reference image. Model every visible part as its own editable object with clean geometry and clear names: boiler, smokestack, domes, cab, headlamp, bell, wheels, rods, tender body and rail track. Keep a neutral gray clay-style material and a simple ground plane with soft shadows so the form is easy to read. Work through a Blender Python script or agent session that creates the objects, and let the detail level be adjustable from simplified to highly detailed. Deliver a .blend file with a tidy outliner hierarchy. Done means the locomotive's silhouette and proportions match the drawing, each part can be selected and moved separately, and it renders cleanly from several angles.
