You will get CATIA Class A Surface Modeling — Automotive & Industrial Product Design
Top Rated
Project details
Class A surface design requires more than CAD proficiency — it demands precision control over curvature continuity, aesthetic intent, and manufacturing feasibility at every stage. With 10+ years in mechanical and product design, a Masters in CAD/CAM, and expert-level CATIA command, I deliver surface models that are geometrically accurate, visually refined, and production-ready from the first delivery.
What I deliver across all tiers: CATIA Class A and Class B surface modeling with full G0, G1, and G2 continuity control. SolidWorks solid and surface modeling for cross-platform compatibility. Detailed 2D technical drawings with GD&T, BOM, and section views formatted to ASME Y14.5, ISO 128, and IS 696 standards. Native CATIA files plus STEP, IGES, and STL exports included in every package.
This service is for automotive designers, product developers, and industrial manufacturers who need production-surface quality work — not just a model that looks good on screen.
Every project begins with a brief consultation to confirm your reference inputs and delivery format. Message me before ordering so I can assess scope and give you an accurate timeline.

Job Success
Bokaro, India - 3:59 pm local time
With 10+ years in mechanical design and product development, a Masters in CAD/CAM, and a Top Rated track record on Upwork, I deliver precision designs that go straight to manufacturing without surprises. My edge is not just CAD proficiency — it is deep manufacturing knowledge in injection molding, sheet metal, and plastic part design, built into every model I create.
Core Services
-3D CAD Modeling and Design — From concept sketches to production-ready models across SolidWorks, CATIA, AutoCAD, and Fusion 360.
-Injection Molding and Plastic Part Design — Draft angles, wall thickness, and fully DFM-compliant geometry.
-Sheet Metal Design — Bend allowances, flat patterns, and tooling-ready drawings.
-2D and 3D Technical Drawings — GD&T, BOM, assembly guides, and manufacturing-ready drafts.
-DFM Reviews and Design Validation — Identifying and resolving costly errors before prototyping or tooling begins.
-Photorealistic Rendering — High-quality visuals for client presentations, marketing, and prototyping reviews.
-CAD File Conversion — Mesh to STEP/IGES, legacy file recovery, and cross-format compatibility.
Why Clients Choose Me
Every design is evaluated for real-world producibility, not just visual accuracy. My academic foundation in CAD/CAM combined with over a decade of hands-on industry experience means I approach each project with both technical depth and practical manufacturing awareness. I manage each engagement from initial concept through material selection, DFM review, and final production-ready deliverables — with an average response time under four hours and clear communication at every stage.

Steps for completing your project
After purchasing the project, send requirements so Ravi can start the project.
Delivery time starts when Ravi receives requirements from you.
Ravi works on your project following the steps below.
Revisions may occur after the delivery date.
Step 1 — Requirements and Reference Review
Client sends all available reference material — sketches, drawings, scan data, images, or sample files. I review inputs, confirm surface quality requirements, and agree on delivery scope before work begins.
Step 2 — Surface Strategy and Approach Plan
I define the surfacing approach — primary surfaces, transition geometry, parting strategy, and continuity targets. For complex parts I share a brief plan for client confirmation before modeling starts.
