Autodesk.Revit.DB.XYZ

origin

The origin of the unbound line.
Autodesk.Revit.DB.XYZ

direction

The direction of the unbound line.

Return Value Line The new unbound line.

// define start point and direction for unbound line
XYZ startPoint = new XYZ(0, 0, 0);
XYZ directionPt = new XYZ(10, 10, 10);

// create line
Line line = Line.CreateUnbound(startPoint, directionPt);

' define start point and direction for unbound line
Dim startPoint As New XYZ(0, 0, 0)
Dim directionPt As New XYZ(10, 10, 10)

' create line
Dim line__1 As Line = Line.CreateUnbound(startPoint, directionPt)
