Points

Here you will find an Array with the point indices in the order in which the points should be arranged on the spline. For this you can, for example, use an Index Array from String Node.

Outlines

Here you can link an Array that contains the number of points that should be used within a segment. For this you can, for example, use an Index Array from String Node. If the spline is made up of a single segment, you will only require the value with the total number of spline points in this Array.

Closed

Here you can link an Array with Boole values that you can, for example, create using a Build Node. These values define for each spline segment, if it should be displayed open or closed. If your line should only consist of a single open segment, this entry is not needed.
