TEACHING SOLID MODELING WITH AUTOCAD Edward. E. Osakue Texas Southern University Houston, TexasAutoCAD is the most popular design drafting software in the world but much of its 3D solidmodeling capabilities are underutilized or neglected. This paper seeks to encourage AutoCADsolid modeling as well as systematize 3D solid modeling principles. Solid modeling is thecreation of an envisioned or existing part or assembly in digital form. A solid model is a digitalmodel of an object and is sometimes referred to as a virtual prototype. It is a complete andunambiguous representation of the object in a precisely enclosed and filled volume in digitalspace. Solid models are used in many industries: engineering, manufacturing, marketing,entertainment, healthcare, etc. Modern manufacturing methods such as rapid prototyping, rapidmanufacturing, and 3D printing use solid model geometries for production.AutoCAD is a computer modeling software from Autodesk that can be used to create traditional2D and 3D geometric models of products. It is the most popular CADD (Computer-AidedDrafting and Design) software in the market worldwide. In fact it is the software commonly usedin introducing CAD stills to students at High Schools, Junior Colleges and in many Universities.AutoCAD is unquestionably the most popular software for 2D design drafting but is not socommonly used in solid modeling. This is largely due to its non-parametric nature as well asprocedural approach in solid modeling. However, with good mastering, AutoCAD solidmodeling is highly versatile and can be competitive in small and mid-sized engineering designand consulting firms who lack financial resources for investment in rapidly changing parametricsolid modelers.This paper explores the teaching of solid modeling using AutoCAD. It presents a proceduraltechnique that helps students to quickly master solid modeling fundamentals. It is based on theauthor’s experience from years of teaching design drafting with AutoCAD as one of the mainsoftware. The procedure is not limited to AutoCAD software because the author has successfullyused the same approach to teach Inventor and Solidworks. The solid modeling technique isoutlined and samples of classroom presentations are provided. Applications for laboratoryexercises and projects by students are discussed and samples are provided.
