About this service

Summary

I provide high-precision CAS surface modeling for automotive concepts and mobility products. With expertise in Class A surfacing, I help bring your car designs to life, ready for visualization, design review, or development stages.

Process

Step 1 – Briefing & References We define the design intent, style direction, and required deliverables. Sketches, blueprints, or base meshes are welcome.
Step 2 – Notion Workspace Access You’ll get access to a shared Notion dashboard to follow progress, feedback loops, milestones and delivery dates.
Step 3 – Curve Network / Base Setup I create a high-quality curve network that ensures flow, tension, and continuity for the surface logic.
Step 4 – Surface Creation I develop smooth, watertight Class A surfaces ready for review, using automotive standards.
Step 5 – Feedback & Final Delivery Preview renders and files are shared. After feedback, I deliver the final models and visuals.

FAQs

  • Can you model over an existing mesh or sketch?

    Yes. I can work from sketches, base meshes or technical blueprints.

  • Do you guarantee Class A quality?

    Yes. I follow curvature continuity, symmetry and surface quality standards expected in the automotive industry.

  • In which formats can I receive the model?

    I can export in IGES, STEP, FBX, OBJ or native format upon request.

  • Can I use the model in Unreal Engine or for visualization?

    Absolutely. I can optimize the model and deliver renders or animation-ready geometry.
