Line Break POP
Summary[edit]
The Line Break POP creates new line strips from the points and line strips of its input.
It can create a set of line strips using an attribute, default named LineBreak, where it steps through all the points of the input and a new line strip is started if the LineBreak attribute is 1. If LineBreak is 0, it continues the line to include current point.
Alternately, It can use a point attribute LineStripIndex (same attribute name as Line Metrics creates) to make separate line strips.
It can also split a line strip based on a point being farther that a specified distance from the previous point.
It can split a line strip every N points.
It can simply create one line strip from its input points.
