The primary goal of 'AutoCAD 2019 Tutorial Second Level 3D Modeling' is to introduce the aspects of computer based three dimensional modeling. It is intended to be used as a training guide for both students and professionals. The chapters in this book cover AutoCAD 2019 and proceed in a pedagogical fashion to guide you from constructing 3D wire frame models, 3D surface models, and 3D solid models to making multiview drawings and rendering images. It takes a hands-on, exercise-intensive approach to all the important 3D modeling techniques and concepts. It also contains a series of twelve tutorial style chapters designed to introduce CAD users to 3D modeling with AutoCAD 2019.
