Sheet Metal application provides an environment for the design of sheet metal parts used in machinery, enclosures, brackets, and other parts normally manufactured with a brake press. Siemens NX CAD sheet metal design software incorporates material and process information in sheet metal-specific modelling features: bends, flanges, tabs, cutouts, beads, dimples, louvres, corner and edge treatments, patterns, and other formable features. You can also quickly convert solid models to sheet metal components, and create sheet metal parts that enclose other components. More than 85% of sheet metal industries use NX CAD as a design tool. 

In this course, you will learn the sheet metal module of NX CAD [UG NX] software. At the end of this course, you will be able to implement sheet metal design constraints. You will also be able to easily create real-time industry models of sheet metals.
