Learning Objectives After completing this chapter, you will be able to: ✓ Change properties on solids. ✓ Align objects. ✓ Rotate objects in three dimensions. ✓ Mirror objects in three dimensions. ✓ Create 3D arrays. ✓ Fillet solid objects. ✓ Chamfer solid objects. ✓ Slice a solid using various methods. ✓ Construct features on solid models. ✓ Remove features from solid models. Changing Properties Using the Changing Properties Using the Properties Palette Properties Palette Properties of 3D objects can be modifi ed using the Properties palette, which is thoroughly discussed in AutoCAD and Its Applications—Basics. This palette is displayed using the PROPERTIES command. You can also select a solid object, right- click, and select Properties from the shortcut menu. The Properties palette lists the properties of the currently selected object. For example, Figure 8-1 lists the properties of a selected solid sphere. Some of its proper- ties are parameters, which is why solid modeling in AutoCAD can be considered para- metric. You can change the sphere’s radius diameter X, Y, Z coordinates linetype linetype scale color layer lineweight and visual settings. The categories and proper- ties available in the Properties palette depend on the selected object. To modify an object property, select the property. Then, enter a new value in the right-hand column. The drawing is updated to refl ect the changes. You can leave the Properties palette open as you continue with your work.
