I have designed (few hand sketches on Inkscape) an aerodynamic add-on for the tip of a wind-turbine blade and now need the concept turned into a clean, presentation-ready 3D model in SolidWorks or similar. I will pass over a full-scale blade STEP file along with several Inkscape sketches showing key cross-sections; the new part has to sit perfectly on the existing tip and follow every curve I have drawn. The visuals matter as much as the fit: the surfaces must be smooth, shiny and free of any faceting so that the model can be used in marketing material and high-resolution renders. Accurate curves and shapes are the top priority, so please plan to use surface-modelling features rather than simple extrudes where needed. When the geometry is finished, I will need two files: the native SolidWorks file for future design iterations and an STL export for rapid prototyping and review. Keep the role and feature tree tidy so my team can follow the logic afterward. If you have any questions about tolerances or alignment with the parent blade, let me know and I can supply extra reference points or curvature data.
