Determining solid properties
Although you can create great-looking models with surfaces, if you want truly realistic models, you need to create solids. After all, in real life, objects have solidity. Even a thin object such as a wastepaper basket or a drape has some thickness. Solids enable you to create more realistic models than surfaces. You can also combine or subtract solids and get information about their physical properties.
AutoCAD LT doesn't draw solids. For the 3D capabilities of AutoCAD LT, see Chapter 21 and 22.
Figure 24.1 shows a complex model created using solids.
As I explain in Chapter 21, when working in 3D, you should use a 3D environment. This includes the following items:
The 3D Modeling workspace, which you choose from the Workspaces toolbar. (I explain how to customize workspaces in Appendix A.)
acadiso3d.dwtor similar template) that turns on perspective view, the grid, and the Realistic or other 3D visual style. (I cover visual styles in Chapter 22.)
The Dashboard palette, which combines many modeling commands and settings in one place.
To work with solids, you can display the Modeling toolbar (right-click any toolbar and choose Modeling). You ...
