Chapter 7
Generating Linework
Chapter 7 focuses on the use of three-dimensional forms and surfaces to generate curve objects. These curve objects can be generated and extracted from surfaces by rebuilding isocurves, working with point grids, and contouring. The tools and techniques for generating linework are very useful for enhancing architectural drawings, by visually suggesting and communicating notions of scale, materials and tectonics, curvature, spatial effects, and other design features.
7.1 Wireframe Linework
Wireframe models consist of points, lines, and curves to depict forms and surfaces. They are useful for visualizing and understanding the geometrical structure of an object. One of the earliest examples of a wireframe drawing is Perspective Study of a Chalice, created by the Italian Renaissance painter Paulo Uccello. (See Figure 7.1) This drawing was intended as a study of a perspectival method for creating the illusion of three-dimensional objects, and consists of a...
