## Handles

Here you can define handle objects, which you can then use to control the spline's points.

### Add

Parameter ID: `ID_CA_IKSPLINE_HANDLE_ADD`

Adds a new entry to the **Handles list**.

### Create

Parameter ID: `ID_CA_IKSPLINE_HANDLE_CREATE`

Creates a null object which is then used as a handle object. This null is assigned automatically to the top entry in the **Handles list** that does not yet have an object assigned in its **Objects** link field.

The tag places the null object at the same position and rotation as the spline point it represents. The **Depth** value is set automatically for the handle so that its tangent matches the spline point's tangent.

### Remove

Parameter ID: `ID_CA_IKSPLINE_HANDLE_REMOVE`

Deletes the entry at the bottom of the **Handles list**.

### List

Here you'll find a list of all the handles that are assigned to the tag. Each handle has the following five settings:

### Index

Parameter ID: `ID_CA_IKSPLINE_HANDLE_INDEX` · Range: [0..2147483647]

Defines the index number of the point that you want the handle to control.

### Object

Parameter ID: `ID_CA_IKSPLINE_HANDLE_LINK`

Drag & drop the object you want to use as the handle into this link field.

### Twist

Parameter ID: `ID_CA_IKSPLINE_HANDLE_TWIST`

Defines whether the handle should also affect twisting for the chain.

[Twist](https://help.maxon.net/c4d/en-us/Content/html/TCAIKSPLINE-ID_TAGPROPERTIES.html.md) must be set to a different option than None.

### Depth

Parameter ID: `ID_CA_IKSPLINE_HANDLE_LENGTH` · Range: [0..+∞m]

Defines the tangent's length for the spline point. This parameter is only available if the spline's **Type** is set to Bezier.

### Offset

Parameter ID: `ID_CA_IKSPLINE_HANDLE_OFFSET`

Shifts the spline point along its tangent by the distance defined here.
