Hi, I am Prasenjit, a professional Freelance Mechanical CAD Design and Drafting Engineer with over 12 years of continuous experience (2014 - 2026) in industrial manufacturing and product development. I strictly specialize in mechanical CAD engineering, leveraging open-source FreeCAD as my primary tool, backed by precision AutoCAD and advanced SolidWorks workflows. Over the past decade, I have successfully transitioned manual concepts and on-site sketches into manufacture-ready, error-free digital models. My Core Expertise Includes: * FreeCAD Parametric Design: Advanced 3D modeling, mechanism assemblies using Assembly4, and variable-driven systems via Spreadsheet expressions. * AutoCAD Mechanical Drafting: High-precision 2D manufacturing drawings, detailed shop blueprints, and layout plans adhering to global engineering standards. * SolidWorks 3D Modeling: Parametric 3D parts, comprehensive top-down assemblies, and proper clearance/fitment optimization. * Reverse Engineering: Expert in physical on-site dimension conversions and legacy part redesigns. * Industrial Mechanism & Gear Design: Calculation and development of high-load gear systems (Spur, Helical, Bevel, Worm) and transmission components. I focus on delivering highly accurate, precise, and production-ready designs that perfectly match client specifications. Let's collaborate to bring your mechanical projects to life
