Drawing from the Model

By: Frank Melendez

Overview of this book

With advances in computing and the invention of computer-aided design (CAD) tools in the 1960s, the production of architectural drawing shifted from hand drafting to computer-aided drafting. Drawing from the Model presents design students and professionals with a broad overview of drawing and modeling in architectural representation. The book starts with an overview of drawing, modeling, and computing, with descriptions and examples of drawings that range from hand sketching to computational visualizations. You’ll also learn about digital physics-based simulations and explore digital drawing and 3D modeling tools, techniques, and workflows for creating geometry in Robert McNeel & Associates Rhinoceros® (Rhino 6 for Windows) software. Moving ahead, you’ll be introduced to conventional architectural drawings, such as plans, sections, and elevations. In the end chapters, you’ll learn about computational design processes, scripting procedures for developing various types of incrementally varying patterns and get an overview of robotics and physical computing platforms. By the end of this book, you’ll have digital drawing and modeling skill sets that are required in contemporary architectural education.

Chapter 8
Generating 2D Projections

Chapter 8 focuses on the generation of two-dimensional projections from 3D models. Geometric objects, such as points, lines, and curves, are created when 3D models are projected onto two-dimensional planes. This geometry can be exported to vector graphics and computer-aided drafting software to create architectural design drawings by assigning line weights, line types, color, text, and other graphic properties. This chapter describes the various types of conventional architectural drawings, which consist of orthographic and perspective projections. Generating projections from 3D models requires an understanding of viewports, cameras, and clipping planes. In addition to conventional architectural drawings, these digital workflows and tools can be implemented and modified to explore experimental methods of generating architectural drawings and representations.
