Model Tree B. 3D toolbar C. 3D object 3D toolbar overview The 3D toolbar appears after you click the 3D model with the Hand tool, which also enables the 3D model and plays any animations associated with it. The 3D toolbar always appears in the area above the upper left corner of the 3D model and cannot be moved. A small blue triangle appears immediately below the 3D toolbar, which you can click to hide and show the toolbar. Note: You can disable or enable the blue triangle toggle by choosing Edit > Preferences (Windows) or Acrobat > Prefer­ ences (Mac OS), selecting 3D under Categories, and then clicking the Enable Toggle For 3D Toolbar Control option. You can use the 3D toolbar to zoom in and out, rotate, and pan across the object. Use the Model Tree to hide or isolate parts, or make parts transparent. You manipulate a 3D model by selecting and dragging various 3D navigation tools. When you navigate in 3D, it may help to think of it as viewing the stationary 3D model from a camera's perspective. You can rotate, pan (move up, down, or side-to-side), and zoom in or out. Note: You can hide the toolbar by right-clicking/Control-clicking the 3D model and choosing Hide Toolbar. To show the toolbar, choose Show Toolbar from the same context menu. 3D navigation tools Rotate Turns 3D objects around relative to the screen. How the objects move depends on the starting view, where you start dragging, and the direction you drag, such as in a straight line or in curves, circles, or loops. Note: You can also use the Hand tool to rotate an object if Enable 3D Selection For The Hand Tool is selected in the 3D panel of the Preferences dialog box. Spin Turns a 3D model in parallel to two fixed axes in the 3D model, the x-axis and the z-axis. Pan Moves the model vertically and horizontally only. You can also pan with the Hand tool: Ctrl­ drag/Command-drag. Zoom Moves you toward, or away from, objects in the scene when you drag vertically. You can also zoom with the Hand tool by holding down Shift as you drag. Walk Pivots horizontally around the scene when you drag horizontally; moves forward or backward in the scene when you drag vertically; maintains a constant elevation level, regardless of how you drag.The Walk tool is especially useful for architectural 3D models. To change the walking speed, change the default display units in the Preferences (3D).
