Click the curve. After a handle is successfully created, the system prompts you to create another handle. To view, change, or turn off the parameters of a handle, open the Information window and select the handle. See the Introduction to the IK on page 180 for more information on using the Information window . Limits and joint information about a handle can be edited in the Skeleton Editor .
Joints can be the end-effector of a maximum of one handle.
This restriction avoids overlapping handles in the modeling windows, and an inability to pick a particular handle. If you need two handles at the same point in the skeleton, you can add additional joints rooted at the same parent. Joints with handles are represented in the SBD window by a handle icon. A handle is always drawn at the joint it controls as the end-effector. By default, it is defined in local space of the skeleton chain.
