Chapter 10 Using Spline Media
526
The Solid Arrow tool is the default tool. Use the Solid Arrow tool to adjust on-screen
controls such as position points, motion paths, and shape outlines or to select shape tracks in
the timeline by clicking in the Composite window. It works with all shapes and media types,
not just splines.
Using the Hollow Arrow Tool
The Hollow Arrow tool is used only with splines. Use it to select a spline object by clicking
the object in the Composite window. When a spline is selected, a bounding box
automatically appears around the spline. Click and drag the bounding box to transform the
spline.
To use the Hollow Arrow tool:
1. Drag a horizontal midpoint of the bounding box to adjust the scale of the object on the X
axis.
2. Drag a vertical midpoint of the bounding box to adjust the scale of the object along the
Y axis.
3. Drag a corner point of the bounding box to adjust the X and Y scale of the spline
simultaneously.
4. Shift-drag to maintain the spline’s aspect ratio.
5. Press the Ctrl key while dragging a corner point to rotate the object.
6. Press the Ctrl key while dragging a midpoint to skew the object.
