![]() To access the Walk tool (it looks like a pair of shoeprints), right-click the 3D model and choose Tools > Walk.The Walk tool, used primarily when working with architectural 3D models, pivots the model horizontally around the scene when you drag horizontally in the document pane, and moves forward or backward in the scene when you drag vertically. Click the Default View button to return to the default view of the model.The 3D Comment tool allows you to add a sticky note that's view-specific. You can also convert measurements to comments. Measurement markups are preserved after the document is closed. Measurements are associated with specific views and are added to the view hierarchy in the Model Tree. When the 3D Measurement tool is selected, specific points and edges are highlighted as you move the pointer over the 3D model. Angle between two edges (or three points).Perpendicular distance between two straight edges.The enhanced 3D Measurement tool in Acrobat 9 supports four types of measurements: You use the 3D Measurement tool to measure part sizes and distances in 3D models. The Camera Properties button opens the Camera Properties dialog box, where you can set the camera angle, alignment, and other properties that define the lens through which the 3D model is viewed. To rotate the camera view, move your pointer into the document pane, click the left mouse button, and drag to turn the camera view. Select the Fly tool to navigate through the model while maintaining the surface orientation.Drag up in the document pane to make the image larger drag down to make the image smaller. To zoom in and out, select the Zoom tool.You can use the Hand tool to rotate an object if Enable Selection for the Hand Tool is selected in the 3D & Multimedia Preferences. With a double-button mouse, holding down both buttons allows you to pan. You also can pan with the Rotate tool by holding down the Ctrl key as you drag. The model moves both vertically and horizontally. Drag up, down, and across the document pane. To pan the model, select the Pan tool.Rotation with the Rotate tool is not constrained in this way. Spinning turns a 3D model parallel to two fixed axes-the x axis and the z axis. Notice that the vertical up-and-down motion is limited. To spin the model, select the Spin tool.Experiment by dragging your pointer down, up, and across while watching the degree and direction of rotation of the model. ![]() ![]() On the Acrobat 3D toolbar, click the Rotate tool to select it, and then drag your pointer in the work area to rotate the model.If necessary, move your pointer over the 3D model to show the 3D toolbar again.Now you'll experiment with manipulating the 3D model by using the tools on the 3D toolbar. The 3D tool, which is used to insert 3D models or animations into PDF documents, is located on the Multimedia toolbar in Acrobat.
