About me
I’m Changzheng, a mechanical CAD designer specializing in manufacturing-oriented design, CNC-ready modeling, and reverse engineering.
I use Siemens NX and SolidWorks to create accurate 3D models, assemblies, and production-ready CAD files.
My focus is practical mechanical design that can move from concept to manufacturing, with attention to accuracy, functionality, and fabrication requirements.
