Book excerpt: The Autodesk(R) Inventor(R) 2022: Advanced Assembly Modeling guide builds on the skills acquired in the Autodesk Inventor 2022: Introduction to Solid Modeling and Autodesk Inventor 2022: Advanced Part Modeling guides to take you to a higher level of productivity when creating and working with assemblies. You begin by focusing on the Top-Down Design workflow. You learn how tools are used to achieve this workflow using Derive, Multi-Body Design, and Layouts. Other topics include model simplification tools, positional representations, model states, iMates and iAssemblies, Frame Generator, Design Accelerator, and file management and duplication techniques. A chapter has also been included about the Autodesk(R) Inventor(R) Studio to teach you how to render, produce, and animate realistic images. Topics Covered Applying motion to existing assembly constraints using Motion and Transitional constraints. Introduction of the Top-Down Design technique for creating assemblies and their components. Tools for Top-Down Design, such as associative links, adaptive parts, multi-body and layout design, derived components, and skeleton models. Creating positional representations to review motion, evaluate the position of assembly components, or document an assembly in a drawing. Using the model simplification tools to create simplified part models and views of assembly designs. Creating model states and iAssemblies to create customizable versions of assembly designs. Creating rendered realistic images and animations of parts and assemblies using Autodesk Inventor Studio and the Video Producer. Using the Design Accelerator and Frame Generator to easily insert standard and customizable components and features into your model. Efficiently duplicating components in an assembly. Adding welds and weld symbols to weldment assemblies. Prerequisites Access to the 2022.0 version of the software, to ensure compatibility with this guide. Future software updates that are released by Autodesk may include changes that are not reflected in this guide. The practices and files included with this guide are not compatible with prior versions (e.g., 2021). The class assumes mastery of Autodesk Inventor basics as taught in Autodesk Inventor: Introduction to Solid Modeling. In addition, Autodesk Inventor: Advanced Part Modeling knowledge is recommended. The use of Microsoft(R) Excel is required for this training course.
