We all know that 3D dynamics blocks can't yet be made in AUTOCAD. But as, Guillermo Melantoni demonstrated during his presentations at AU2011 and AU2010, you can still achieve that by a wise use of constraints, parameters and surface modeling with associativity.
This serie of videos are aimed to demonstrate a typical workflow for a simple object. For more insight, please watch Guillermo's presentation "Scare Your Colleagues: Parametric Surface Modeling, Blocks, and Arrays with AutoCAD® 2012" (session ID: AC4054-P) at [ Ссылка ]
