In the previous chapters, we saw the different commands that are available for creating 3D solid objects. Alongside the modify commands, these commands have a countless number of options when it comes to creating 3D shapes, and although using the commands described in the previous chapters (Chapter 10, Introduction to 3D Modeling, Chapter 11, Creating Primitive 3D Shapes, and Chapter 12, Conversion between 2D and 3D) can be used to create almost any 3D model, AutoCAD offers other types of 3D objects that represent different approaches to creating 3D models. These types have different creation methods, different properties, and different modification possibilities.
The first type is surface modeling, where surfaces will be used to represent the 3D model instead of 3D solids. In surface modeling, you can associate the created surfaces with other objects...
