This lets you add springs to strokes with tubes to give the tubes reactive, interconnected motion. By animating the movement of the surface with the springed tubes on it, the tubes will react appropriately.

These are the options in the Make Brush Spring Options window.

Spring Stiffness

Defines the rigidity of the brush spring. If you increase the stiffness too much, the brush spring might stretch and contract excessively.

Spring Damp

Defines a damping value to mute the spring action. A high value causes the spring length to change more slowly. A low value causes the length to change quickly.

Spring Travel

Defines how far the stroke tubes can swing.

Start Frame

Sets the frame in which the spring behavior begins.
