CAD Design & Mechanical Engineering Freelancer

CAD Drafting Services Lanka • Freelance

Aug 2024 - Present • 2 yrs 1 mo

I provide professional CAD design and mechanical engineering services for clients requiring accurate, practical, and manufacturing-ready solutions. I create detailed 3D models, assemblies, sheet metal components, mechanical parts, frames, brackets, and product concepts using SolidWorks. My work includes converting sketches, engineering specifications, reference images, and concepts into precise CAD models suitable for prototyping and manufacturing. I also prepare technical drawings with dimensions, tolerances, sections, annotations, and assembly details to clearly communicate design requirements. I deliver production-ready files in formats such as STEP, STL, PDF, and native SolidWorks formats. I focus on design accuracy, functionality, manufacturability, and clear technical documentation. Key achievements: • Successfully converted complex engineering concepts into practical CAD models. • Produced detailed manufacturing drawings for mechanical components and assemblies. • Improved designs for easier fabrication, assembly, and production. • Delivered reliable CAD solutions while maintaining clear communication and attention to client requirements.
