online(Line, Distance) & onliner(Line, Relative distance) & onlinex(Line, X coordinate) & onliney(Line, Y coordinate) &onlinez(Line, Z coordinate)

online(Line, Distance) → [X coordinate (number), Y coordinate (number), Z coordinate (number)]

This function calculates the point coordinate at the exact given distance along a line defined by its start and end coordinate values. onliner(Line, Relative distance) → [X coordinate (number), Y coordinate (number), Z coordinate (number)]

This function calculates the point coordinate at the exact relative distance along a line defined by its start and end coordinate values. (0) specifies the start point and (1) specifies the end point. onlinex(Line, X coordinate) → [X coordinate (number), Y coordinate (number), Z coordinate (number)]

This function calculates the point coordinate given X coordinate along a line defined by its start and end coordinate values. onliney(Line, Y coordinate) → [X coordinate (number), Y coordinate (number), Z coordinate (number)]

This function calculates the point coordinate given Y coordinate along a line defined by its start and end coordinate values. onlinez(Line, Z coordinate) → [X coordinate (number), Y coordinate (number), Z coordinate (number)]

This function calculates the point coordinate given Z coordinate along a line defined by its start and end coordinate values.
