Copyright Goodheart-Willcox Co., Inc. 178 AutoCAD and Its Applications—Advanced Move and Rotate Objects in 3D Space The basic operation of moving and rotating an object relative to a second object or set of points is done with the 3DALIGN command. It allows you to reorient an object in 3D space. Using this command, you can correct errors of 3D construction and quickly manipulate 3D objects. The 3DALIGN command requires existing points (source) and the new location of those existing points (destination). For example, refer to Figure 8-5. The wedge in Figure 8-5A is aligned in its new position in Figure 8-5B as follows. Set the Intersection or Endpoint running object snap to make point selection easier. Refer to the fi gure for the pick points.
