Position[XYZ m]

Here you will receive the global position of the assigned spline curve, which reflects the Offsset value.

Tangent[XYZ m]

This vector defines the tangent on the spline curve at the queried position. You can, for example, use this information to position the object that should be moved along the spline.

Segment Count[0..2147483647]

Here you can output the number of segments along the spline.

Is Closed

This output will let you know if the spline is open or closed. The output will be a Boole value.

Length[-∞..+∞m]

Here the length of the spline will be output. If the spline contains multiple segments, the Segment Index setting can be used to only output the length of a specific spline segment.

Matrix

Here the matrix of the linked spline will be output.
