Chapter 5
2D Drawing
Chapter 5 describes some of the primary geometric elements that are used to create two-dimensional drawings within the 3D modeling environment, including points, line segments, and curves. This overview of point and curve objects, B-splines, Bézier curves, and NURBS (nonuniform rational B-splines) is intended to provide the reader with a better understanding of the computations utilized for generating curves within the Rhino 3D modeling environment, and a foundation for learning more advanced concepts related to programming. Methods for editing curve control points, and tools and techniques for creating, replicating, editing, and transforming two-dimensional geometry are provided as a means for creating design drawings and 3D models.
5.1 Drafting
Architectural drawings are two-dimensional projections that describe three-dimensional forms and spaces. Historically, two-dimensional architectural drawings, such as floor plans, elevations, sections, and axonometrics...
