Professional CAD modeling with 26 years of manufacturing knowledge. Every model reviewed for manufacturability — not just drawn, but engineered. German quality standards, Indian efficiency.

You need CAD models — but most CAD operators just draw what you ask for. They don't question manufacturability, don't suggest cost reductions, and don't understand German engineering standards. Direct offshore outsourcing saves money but creates quality problems. German firms charge €80-150/hour.
I provide CAD modeling with built-in DFM review. Every model is checked: Can it be made? What will it cost? Is there a simpler way? For membrane modules, lab equipment, and sheet metal parts, I execute directly in SolidWorks. For complex automotive or large assembly projects, I coordinate experienced Indian CAD partners with my technical oversight.
You get manufacturing-ready models at 30-50% less than German CAD services. Models follow DIN/ISO standards with proper GD&T. 2 revision rounds included. Optional prototype coordination through my own facility (S.S.S Laser Industries).
Project-based pricing. No hidden markup. Full cost breakdown provided in every quote.
