This textbook describes the construction of sheet metal bending parts using Sheetmetal Design in CATIA V5-6. The step-by-step guide clearly demonstrates the efficient design of simple to complex sheet metal bending parts and rolled sheet parts within the Sheetmetal Design environment. In addition to explaining the basic functions and design methodology, including the design sequence, many practice examples reinforce the learned material. Solutions to common error messages, as well as tips and tricks, assist the reader. Furthermore, new functional features such as freeform surfaces and offset functions from the CATIA Release 2014 have been incorporated.
