NX is the commercial CAD/CAM/CAE PLM software suite developed by Siemens PLM Software. NX is widely used in the engineering industry, especially
in the automotive and aerospace sectors.[http://www.plm.automation.siemens.com/en_us/products/nx/index.shtml]
NX is a next-generation digital product development system that helps companies transform the product lifecycle. With the industry's broadest suite of integrated, fully associative CAD/CAM/CAE applications, NX touches the full range of development processes in product design, manufacturing and simulation.
NX provides a complete suite of integrated process automation tools to enable companies to capture and reuse product and process knowledge encouraging the use of corporate best practice.
Features: NX is commonly referred to as a 3D PLM software application. The product supports all stages of product development from conceptualization (CAID), to design (CAD), to analysis (CAE), to manufacturing (CAM). NX integrates these product lifecycle stages into an end-to-end process using concurrent engineering workflow, design-in-context and product data management tools that apply across all functional areas. The 2008 release of NX, version 6, provides capabilities which apply across all core functional areas and are intended to benefit new as well as advanced and specialized users. Four key portfolio-wide innovations include:
Design Flexibility: A synchronous technology combining constraint-driven techniques with direct modeling, is used to provide direct editing in the model creation process. Further flexibility is provided through: Active digital mock-up: A capability referred to as Active Mockup. This feature allows the use of a multi-CAD digital mock-up for visualization and the ability to modify the model within the mock-up.
