Autodesk inventor is a product of Autodesk inc. Autodesk inventor 2018 is a parametric, feature-based solid modeling tool that not only unites the three-dimensional (3D) parametric features with two-dimensional (2D) tools, but also addresses every design-through-manufacturing process. The continuous enhancements in the software has made it a complete plm software. The software is capable of performing analysis with an ease. Its compatibility with cam software is remarkable. This solid modeling tool is remarkably user- friendly and it allows you to be productive from day one. The book follows a step by step methodology. In this book, author tried to give real-world examples with real challenges in designing. Author tried to reduce the gap between University use of Autodesk inventor and industrial use of Autodesk inventor. Book includes topics on sketching, 3D part designing, assembly design, sheetmetal, weldments, mold design, surface design, structural analysis, 3D printing, mbd (model based definition), 3D DFS, and many other topics. The book covers almost all the information required by a learner to master the Autodesk inventor. The book starts with sketching and ends at advanced topics like mold design, sheetmetal, weldment, and mbd.
