© 2011 Autodesk Class Summary Creating, Manipulating & Animating AutoCAD Assemblies  Quick Review of Parametric Constraints in AutoCAD  Creating 3D Block Parts  Use Geometric Constraints to Assemble Block Parts  Use Parametric Dimensions to Edit Component Positions  Writing Simple LISP Routines to Animate Assemblies

© 2011 Autodesk Learning Objectives At the end of this class, you will be able to:  Create 3D block parts with connection geometry  Use geometric constraints to create mechanical assemblies  Apply parametric dimensions to assemblies to edit component position  Create a “skeleton frame” that is suitable for assembling blocks  Drive motion within an assembly through the use of simple LISP routines
