Describes a line segment in 2D space To create a line there are several ways: Part.Geom2d.Line2dSegment() Creates a default line Part.Geom2d.Line2dSegment(Line) Creates a copy of the given line Part.Geom2d.Line2dSegment(Point1,Point2) Creates a line that goes through two given points Set the parameter range of the underlying line segment geometry Returns the start point of this line segment. Returns the end point of this line segment.
