Update v2.0:
1- Now, in addition to the existing method, you can create a Line using 2 points, and the Line will use the length spinner.
2- You can load an existing Line (that has only 2 vertices), and change its length while respecting its orientation.
3- The script now will not discard any existing modifiers when you change the length.
...and more
(Please refer to the video tutorial for a full explanation)


To Use:
	 You have two methods to create the parametric line:
	 1- Choose values for the rotation using the X-Angle, Y-Angle, Z-Angle.
		 Click Create Line and click in the viewport to create a line with the length sepcified in the Length: spinner.
		 You can change the Length of the last created line using the Length spinner.
		 Remember that if the last created line is selected and you want to create another one, you need to press the Create Line before changing the Length
		 Otherwise you'll be changing the length of the last created Line.
		 Or you can deselect the line so you can define the length before clicking the Create Line button.
		 The created Line must be selected to be able to change its length
	 -------------------------------------------------------------------
	 2- You can use the 'Using Two Points' method (check the option to activate it)
		 By pressing the button and clicking twice in the viewport to specify the start and the end points of the line.
		 The Line will start at the first picked point and it will point towards the second picked point
		 It will use the length specified in the Length spinner.
		 The Distance between points readout indicates the distance between the 2 points.
		 Click the Use Full Length button to use the readout value as the Line's length.
	 -------------------------------------------------------------------\n"
	 3- In the Extras group you can click the button to load an existing line in the scene.
		 The script will only consider the first entry in the stack.
		 And that entry must be a 2D shape with 2 vertices only.
		 The Pivot To Endpoint 1 will make sure the pivot point is always at the start point of the Line.
		 Uncheck it to preserve the current position of the pivot.
