Copyright Goodheart-Willcox Co., Inc. 182 AutoCAD and Its Applications—Advanced 3D Moving 3D Moving The 3DMOVE command allows you to quickly move an object along any axis or plane of the current UCS. When the command is initiated, you are prompted to select the objects to move. If the 2D Wireframe visual style is current, the visual style is tempo- rarily changed to the Wireframe visual style because the gizmo is not displayed in 2D mode. After selecting the objects, press [Enter]. The move gizmo is displayed in the center of the selection set. By default, the move gizmo is also displayed when a solid is selected with no command active. The move gizmo is a tripod that appears similar to the shaded UCS icon. Refer to Figure 8-8A. You can relocate the tool by right-clicking on the gizmo and selecting Relocate Gizmo from the shortcut menu. Then, move the gizmo to a new location and pick. You can also realign the gizmo using the shortcut menu. If you move the pointer over the X, Y, or Z axis of the gizmo, the axis changes to yellow. To restrict movement along that axis, pick the axis. If you move the pointer over one of the right angles at the origin of the gizmo, the corresponding two axes turn yellow. Pick to restrict the movement to that plane. You can complete the movement by either picking a new point or by direct distance entry. NOTE NOTE If the GTAUTO system variable is set to 1, the move gizmo is displayed when a solid is selected with no command active. If the GTLOCATION system variable is set to 0, the gizmo is placed at the same location as the UCS icon. Both variables are set to 1 by default. 3D Rotating 3D Rotating As you have seen in earlier chapters, the ROTATE command can be used to rotate 3D objects. However, the command can only rotate objects in the XY plane of the current UCS. This is why you had to change UCSs to properly rotate objects. The 3DROTATE command, on the other hand, can rotate objects on any axis regardless of the current UCS. This is an extremely powerful editing and design tool. When the command is initiated, you are prompted to select the object(s) to rotate. After selecting the objects, press [Enter]. The rotate gizmo is displayed in the center of the selection set. The gizmo provides you with a dynamic, graphic representation of the three axes of rotation. Refer to Figure 8-8B. After selecting the objects, you must specify a location for the gizmo, which is the base point for rotation. Now, you can use the gizmo to rotate the objects about the tool’s local X, Y, or Z axis. As you hover the cursor over one of the three circles in the gizmo, a vector is displayed that represents the axis of rotation. To rotate about the tool’s X axis, pick the red circle on the gizmo. To rotate about the Y axis, pick the green circle. To rotate about the Z axis, pick the blue circle. Once you select a circle, it turns yellow and you are prompted for the start point of the rotation angle. You can enter a direct angle at this prompt or pick the fi rst of two points defi ning the angle of rotation. When the rotation angle is defi ned, the object is rotated about the selected axis. The following example rotates the bend in the HVAC assembly shown in Figure 8-9A. Set the Center of face 3D object snap.
