Book excerpt: This text presents a tutorial-based introduction to solid modeling and the SOLIDWORKS software.Although the tutorials can be followed by anyone interested in learning the software, it is geared toward freshman engineering students or high school students interested in engineering. Accordingly, the examples and problems are based on the authors’ experience with teaching engineering students. This text primarily consists of chapter-long tutorials, which introduce both basic concepts in solid modeling (such as part modeling, drawing creation, and assembly modeling) and more advanced applications of solid modeling in engineering analysis and design (such as mechanism modeling, mold creation, sheet metal bending, andrapid prototyping). Each tutorial is organized as “keystroke-level” instructions, designed to teach the use of the software.
