Seyed Sajjad M.

I help manufacturers, engineering firms, and product developers turn concepts, STEP files, and existing drawings into accurate, fabrication-ready SolidWorks models and manufacturing documentation. With over 10 years of experience in mechanical design and manufacturing, I provide editable 3D CAD models, detailed part and assembly drawings, structured BOMs, sheet-metal designs, welded assemblies, and DFM improvements for practical production. My services include: • Mechanical parts and assemblies in SolidWorks • Fabrication and manufacturing drawings • Sheet-metal and welded structure design • STEP model review and native CAD reconstruction • BOMs, part numbering, tolerances, and production documentation • DFM review and design improvement for machining, cutting, bending, and welding My background includes industrial equipment, process skids, steel structures, pressure equipment, sheet-metal products, and custom mechanical assemblies. I focus on clear communication, realistic scheduling, and CAD deliverables that can be used directly for manufacturing.
