## DESCRIPTION

**This node specifies a piecewise-linear curve that is used as a profile for either a trimming patch of a Nurbs surface or for the bevel of SoText3**. The **index** field indexes into the current profile coordinates (specified in an **SoProfileCoordinate2** or **SoProfileCoordinate3** node). If the last value of the **index** field is **SO\_LINEAR\_PROFILE\_USE\_REST\_OF\_VERTICES** (-1), all remaining coordinates in the current coordinates will be used, starting with the coordinate after the previous index (all coordinates will be used if **SO\_LINEAR\_PROFILE\_USE\_REST\_OF\_VERTICES** is the only value in the **index** field). For example, if **index** contains the values **\[2,0,-1\]** and there are 4 profile coordinates (0-3), it is as if the **index** field contains **\[2,0,1,2,3\]**.

## METHODS

	**SoLinearProfile()**\
 Creates a linear profile node with default settings.

**static SoType**	**getClassTypeId()**\
 Returns type identifier for this class.

## ACTION BEHAVIOR

**SoGLRenderAction, SoRayPickAction, SoCallbackAction**\
 Adds a profile to the current state.

## FILE FORMAT/DEFAULTS

```
LinearProfile {
index	0
linkage	START_FIRST
}
```
