In Chapter 4, Creating Solids and Surfaces from 2D, we introduced how to create surfaces by applying
EXTRUDE and other commands to linear objects. This chapter is about all types of surfaces and meshes.
The topics covered in this chapter are:
Identifying types of surfaces and their applications
How to create and edit procedural surfaces
How to create and edit NURBS surfaces
How to create and edit meshes
How to create meshes based on 3D faces
Analyzing surfaces curvature
Surfaces and meshes are 3D objects with zero thickness. Most of the time, when modeling in 3D, we apply solids, which give us much better precision; since Version 2010, surfaces and meshes are also available, and can be used for complex and conceptual models. These objects are divided into the following categories:
Procedural surfaces: These are surfaces created from linear objects, such as
SWEEP, as we have seen in Chapter 4, Creating Solids and Surfaces from 2D. These surfaces...
