Autodesk Inventor 2021 : Ascent, Center for Technical Knowledge : 9781952866487 : 1952866480 : 19 Aug 2020 : The Autodesk(R) Inventor(R) 2021: Surface and Freeform Modeling guide teaches you how to incorporate surfacing and freeform modeling techniques into your design environment. You begin with instruction on how to create the splines and 3D sketches commonly used in surface creation. Chapters on surface creation focus on using these sketches or existing geometry to create surfaces for use in your solid models. Freeform modeling is also covered, which enables you to create complex shapes without needing the constraints required in a parametric workflow. To complete the guide, you will learn how to use the Autodesk Inventor surface analysis tools to evaluate the continuity between surfaces and the curvature on a surface, determine if the applied draft is within a specified range, and conduct section analysis to evaluate wall thickness values. The topics covered in this guide are also
