Camera properties make up a camera view, which can be used both between views and between files. 1 On the 3D toolbar, click the Camera Properties icon . If you don't see the icon, click the arrow next to the navigation tool on the left side of the 3D toolbar. 2 In the Camera Properties dialog box, click Save As to name a new camera view, or select an existing view from the menu. 3 Move the Camera Properties dialog box so that you can see the 3D model. Select a camera alignment: • Select Target to align the camera properties only to the target position. • Select Camera And Target to align the camera properties to both the camera direction and the target position. 4 Select the type of alignment: Select Model After you select this option, click a 3D model in the document. The Camera Properties dialog box shows the current camera position. • If Target is selected, the new position of the camera target is the center of the selected model. • If Camera And Target is selected, the position of the camera target is the center of the selected model. The camera is aligned to the selected model. Select Face After you select this option, click a face of the 3D model in the document. The Camera Properties dialog box shows the current camera position. • If Target is selected, the new position of the camera target is the center of the selected face. • If Camera And Target is selected, the position of the camera target is the center of the selected face. The camera is aligned to this face. Select 3 Points After you select this option, select three points on the same or different models in the document. The Camera Properties dialog box shows the current camera position. • If Target is selected, the new position of the camera target is the center of the three selected points. • If Camera and Target are selected, the camera target is the center of the three selected points. The camera position is aligned to the plan composed by the three selected points. 5 In the Position section, select Angle Units to change the X, Y, and Z values to Azimuth, Altitude, and Distance. These values enable you to manipulate the camera by azimuth (distance) and altitude (X axis), and to zoom using the distance value. 6 Move the sliders in the Camera and Target positions to the desired location. 7 To change the focal angle of the camera, drag the Field Of View slider to the desired degree. 8 To change the roll angle of the camera, drag the Roll slider to the desired degree. 9 Click Save Camera View to save the settings and add the view to the Model Tree. The view is added to the Model Tree with the default name of CameraView[n], with [n] being an incremental number. You can rename the camera view in the Views list. Last updated 10/11/2011
