Title: Convert 2D Patent Drawings (XPeng Humanoid Leg) into 3D CAD Model Description: I have a Chinese patent PDF (CN119262120A) that contains 2D line drawings of a humanoid robotic leg and ankle structure. The figures show the calf support, foot support, ankle joint, and dual linear actuators. I need a skilled CAD designer to: Convert these 2D patent drawings (Figures 1–7) into a 3D CAD assembly. Model all key parts: calf support, foot support, ankle joint, actuators, and mounting brackets. Assemble the model with realistic joint constraints (hip, knee, ankle). Simulate actuator extension/retraction to verify ankle movement around two axes. Deliver editable CAD files (STEP, IGES, SolidWorks, or Fusion 360). Provide STL/FBX files for visualization. Requirements: Experience with mechanical CAD design (SolidWorks, Fusion 360, or similar). Ability to work from 2D sketches without full dimensions (you may need to scale/estimate proportions). Familiarity with robotic leg mechanisms is a plus. Deliverables: Editable parametric CAD files (STEP/IGES/SolidWorks). STL/FBX files for visualization. Basic motion test/animation showing actuator-driven ankle movement.
