Chapter 4
The 3D Modeling Environment
Chapter 4 describes 3D modeling surface types and provides an overview of the Rhino 6 for Windows modeling environment. This chapter also describes the organization of the interface, which includes the 3D modeling viewports, toolbars, and menus for accessing commands that create and transform geometric objects. Units, modeling aids, layers, and object properties, can be utilized for creating accurate, precise, and organized, two-dimensional drawings and three-dimensional models. These drawings and models can be visualized in various formats, such as wireframe, shaded, and rendered views.
4.1 Surface Types
3D modeling environments use Cartesian coordinate systems to define the locations of points in space based on their distances from the origin of the X, Y, and Z axes. Points are used as the underlying elements that define other geometry, such as lines, curves, planes, and surfaces. Two points can be used to describe a line, two intersecting...
