NX CAD is an advanced 3D modeling tool for drafting, and simulation capabilities that can be used by engineers and designers in developing and validating sophisticated products. Siemens NX CAD is widely used for product design, engineering and manufacturing. NX CAM software is designed to automate NC programming, increase machining rates, and manufacture accurate parts with the help of enhanced toolpath technologies and G-code simulation. NX CAM system comprises a full package of numerical control (NC) programming solutions and a suite of manufacturing software tools.
