Define and Change Views with ShowMotion Using ShowMotion, you can add movement and transitions to a saved view. These saved views are called shots. The types of shots that you can create are: • Still. Utilizes a single fixed camera position. • Cinematic. Utilizes a single camera with cinematic camera movements. • Recorded Walk. Records an animation by navigating around and through a model. DEMO VIDEO Shot Sequences Shot sequences are used to organize related shots together. These sequences are also called view categories. By using shot sequences, you can do the following: • Quickly locate a shot • Play back more than one shot at a time • Control the order in which shots are played back ShowMotion is made up of three main parts: shot thumbnails, shot sequence thumbnails, and the ShowMotion control. With the ShowMotion control, which is along the bottom, you can play the animations assigned to a shot, pin and unpin ShowMotion, and close ShowMotion. Use the shot and shot sequence thumbnails to navigate the shots in the current model. The ShowMotion control has the following options: • Pin/Unpin ShowMotion. Pins ShowMotion so the ShowMotion control and all thumbnails remain displayed even if focus is shifted away from ShowMotion. When ShowMotion is not pinned, the ShowMotion control and all thumbnails disappear if the focus is switched away from ShowMotion. • Play All. Starts the playback of shots in all shot sequences. Shots are played left to right, starting with the leftmost shot sequence. • Stop. Stops the playback of the current shot. • Turn On/Off Looping. Enables or disables playback looping for the animation assigned to the shot or shot sequence when played back. • New Shot. Displays the New View/Shot Properties dialog box where you can create a new shot. • Close ShowMotion. Closes the ShowMotion control and all thumbnails. To launch ShowMotion Use one of the following methods to launch ShowMotion • Click View ShowMotion. • On the status bar, click ShowMotion. COMMAND NAVSMOTION Displays the ShowMotion interface. Overview of Cameras You can place a camera in a drawing to define a 3D view. There are several ways to change camera settings: • Click and drag grips to resize or relocate a lens length or field of view. Use the Dynamic Input tooltip to enter X,Y, Z coordinate values. + Modify camera properties in the Camera Properties palette. Commands CAMERA Sets a camera and target location to create and save a 3D perspective view of objects. Create Motion Path Animations Motion path animations, such as 3D animated walk-throughs of a model, allow you to visually demonstrate a model to both a technical and non-technical audience. You can record and play back a navigation to communicate your design intent dynamically. Control a Camera Motion Path You control the camera motion, and therefore the animation, by linking the camera and its target to a point or a path. To create an animation using motion paths, you link the camera and its target to either a point or a path. If you want the camera to remain still, link it to a point. If you want the camera to move along a path, link it to a path. If you want the target to remain still, link it to a point. If you want the target to move, link it to a path. You cannot link both the camera and the target to a point. Use the same path when you want the animation view to follow in line with the camera's path. You do this by setting the target's path to None in the Motion Path Animation dialog box. This is the default setting. NoteTo link a camera or target to a path, you must create the path object before you create the motion path animation. A path can be a line, arc, elliptical arc, circle, polyline, 3D polyline, or spline. To create a motion path animation 1. In the drawing, create a path object for either the camera or the target. A path can be a line, arc, elliptical arc, circle, polyline, 3D polyline, or spline. NoteThe path you create is not visible in the animation. 2. If the Animations panel is not displayed on the Render tab, right-click the Render tab and click Panels Animations. 3. Click Render tab Animations panel Animation Motion Path. 4. In the Motion Path Animation dialog box, Camera section, click either Point or Path. 5. Do one of the following: • To specify a new camera point, click the Pick Point button, and specify a point in the drawing. Enter a name for the point. Click OK. • To specify a new camera path, click the Select Path button, and specify a path in the drawing. Enter a name for the path. Click OK. • To specify an existing camera point or path, select it from the drop-down list. 6. In the Motion Path Animation dialog box, Target section, click either Point or Path. 7. Do one of the following: • To specify a new target point, click the Pick Point button, and specify a point in the drawing. Enter a name for the point. Click OK. • To specify a new target path, click the Select Path button, and specify a path in the drawing. Enter a name for the path. Click OK. • To specify an existing target point or path, select it from the drop-down list. 8. In the Animation Settings section, adjust the animation settings to create the animation to suit your needs. 9. When you have finished adjusting the points, paths, and settings, click Preview to view the animation, or OK to save it. Commands ANIPATH Saves an animation file of a camera moving or panning in a 3D model. Specify Motion Path Settings You determine the format of the animation file of a motion path animation by specifying settings in the Motion Path Animation dialog box. Several settings control the animation's frame rate, duration, resolution, visual style, and file format. To view a reverse motion path animation 1. If the Animations panel is not displayed on the Render tab, right-click the Render tab and click Panels Animations. 2. Click Render tab Animations panel Animation Motion Path. 3. In the Motion Path Animation dialog box, Animation Settings section, click the Reverse check box. 4. Click OK. To control the speed and duration of the animation 1. If the Animations panel is not displayed on the Render tab, right-click the Render tab and click Panels Animations. 2. Click Render tab Animations panel Animation Motion Path. 3. In the Motion Path Animation dialog box, Animation Settings section, specify a Frame rate (FPS). 4. Do one of the following: • Specify a number of frames. • Specify a duration, in seconds. 5. Click Preview or OK. To set animation resolution 1. If the Animations panel is not displayed on the Render tab, right-click the Render tab and click Panels Animations. 2. Click Render tab Animations panel Animation Motion Path.
