The first step in creating an animation is defining a path for the camera to follow. You can specify where you want the camera to look (along the path or at a specific target), as well as the view angle.
You draw the path by selecting a camera start point and subsequent control points. The path automatically curves between points to create a smooth motion for the camera. Once you have drawn the path, you can add, remove and elevate control points if you want.
You can draw more than one path if you want. By default, all paths will be included in the animation, and will be followed in the order in which they were drawn. You can, however, choose which paths you want to include in the animation, as well as the order of paths for the camera to follow.
To draw an animation path:
Make sure that the location on which you want to capture the animation is the current building location. Also, it is recommended that you draw the path while in 2D plan view.
Select Tools
> Animation > Insert Path, or click the Insert Path button
on the Animation toolbar.
In the Path Properties dialog, specify a name for the path for identification purposes.
In the Behavior area, specify what you want the camera to focus on during the animation. If you select Follow Path, the camera will focus on a different target along the path in each frame. If you select Specify Target, the camera will always point towards a target point that you specify.
In the View Angle area, specify how wide you want the view angle to be by either sliding the ruler or entering a value in the edit box. Higher values produce a wide-angle view; lower values produce a close-up view.
Click OK.
Select a start point for the camera. For example, if you want to start your animation by walking through the front door, select a point outside the front door.
If you selected the Specify Target option, select the point you want to the camera to remain focused on during the animation.
Select the next point of the path. Each point you select is called a control point. The camera will move to each control point and capture an image of the view at that point. Basically, control points are the key to drawing and shaping your path. Example
Continue selecting control points until your path is finished.
Right-click and select Finish. You can now preview the animation.
