Project details
I am a Senior Mechanical Design Engineer specializing in precision CAD modifications and design refinement using SolidWorks. I help clients improve existing parts and assemblies by applying proper design intent, parametric control, and manufacturability considerations.
This service is ideal when you already have a 3D model and need reliable updates—such as feature changes, dimensional adjustments, or assembly-level refinements—while keeping the model clean, stable, and production-ready.
My focus is not just on editing geometry, but on delivering engineering-grade CAD that can be confidently used for manufacturing, prototyping, or further development.
Services Offered
Modify existing SolidWorks parts (features, dimensions, parametric updates)
Assembly-level refinements with proper fit and alignment
Design clean-up and manufacturability improvements
Updated 2D drawings and basic BOMs (if required)
Export in standard manufacturing formats (STEP, PDF, DWG, native files)
Important Note
Patent-style drawings are provided as engineering support only, not legal advice.

Product Update and Design.
I would like to share with everyone that my experience with Manikandan was yet again another great one. I have worked with him in the past on various projects related to my different dreams.
And wow, does he bring them to life! He listens, he's patient, and is extremely skillful at what he does. He can translate my confusion into masterful work. I would definitely work with him again. As a matter of fact, I'm about to hire him for another. He has strong work ethics and is always timely and professional as my designer.

Thiruvarur, India - 9:18 pm local time
I help startups, product developers, and manufacturers turn ideas, sketches, existing products, and technical requirements into accurate SolidWorks models and production-ready documentation.
I am a Certified SolidWorks Professional (CSWP) and Senior Mechanical Design Engineer with over 13 years of experience in product development and manufacturing design.
I am an Upwork Top Rated Plus freelancer with a 99% Job Success Score, more than $100K earned, over 5,900 hours worked, and 380 successfully completed projects. I am also recognized as a Cad Crowd Top Designer and Gold Award winner.
My experience includes SolidWorks parts and assemblies, mechanical mechanisms, sheet-metal enclosures, fabricated structures, CNC-machined components, plastic parts, injection-molding DFM, 3D-printable models, reverse engineering, ISO GD&T, FEA, BOMs, exploded views, and detailed manufacturing drawings.
I can support your project with:
Concept development and mechanical design
SolidWorks 3D modeling and assemblies
Product redesign and design improvement
Sheet-metal parts, cabinets, covers, and flat patterns
CNC components and manufacturing drawings
Plastic enclosures and injection-molding design
3D-printable STEP and STL files
Reverse engineering from samples, images, or measurements
FEA and basic mechanical validation
GD&T, BOMs, DXF files, and production documentation
My work covers consumer products, electronic enclosures, machinery, manufacturing fixtures, welded structures, aerospace equipment, display models, prototypes, and custom mechanical assemblies.
I focus on practical engineering, manufacturability, dimensional accuracy, organized CAD files, clear communication, confidentiality, and dependable delivery. My goal is to provide designs that look professional, function correctly, and can be manufactured efficiently.
Whether you need a new product developed, an existing design reconstructed, a prototype prepared for 3D printing, or a complete manufacturing package, I can support the project from initial concept through final production release.
