Part 2
3D Modeling and Geometry
Part 2 provides an overview of the 3D modeling environment, as well as concepts and techniques that demonstrate methods for generating two-dimensional projections from 3D models. The ability to create 3D models with precision and efficiency requires an understanding of coordinate systems, metrics, and conventions of architectural drawing. This section introduces fundamental geometries for creating digital drawings and models, such as points, lines, and surfaces. Descriptions of vectors, splines, and NURBS geometry provide an understanding of the mechanics of 3D models and geometry, which can be created and manipulated to represent various shapes and forms ranging from simple to complex.
This section introduces tools, techniques, and workflows for generating geometry with extrusions, translations, rotations, and lofts. These processes yield various types of surfaces, such as planes, ruled surfaces, and doubly curved surfaces, which are defined and depicted...
