It seems that each of the two curves would need to have an orientationlist , to control which end is blended ?

Would the order inside get.Input(1).getValue() be orient1, seam1, orient2, seam2 ?

What is the proper way to make the new orientlist for setInput(1, orientlist) ?

The following code does not change the blending order. G3 Blending still occurs between the closest ends of the 2 curves.

    var blendfactory = moi.command.createFactory( 'blend' );

               blendfactory.setInput( 0, curvelist );
//            blendfactory.setInput( 1,  orientationlist );
               blendfactory.setInput( 2, 'G1' ); //versus 'G2' or 'G3'
               blendfactory.setInput( 3, 1.00 );
//            blendfactory.setInput( 4, pointlist );
//            blendfactory.setInput( 5, vector );

	var bCurve = blendfactory.calculate();
	var orientations = blendfactory.getInput(1).getValue();
	blendfactory.cancel();				
	var orient = orientations.item(0);
	orient.flipped = !orient.flipped;

	var seamvalue = orientations.item(1); //try to get the (un-needed) seam for the new orientlist ?
			
	var orientlist = concat(orient.flipped, seamvalue.seam); //try to make a new orientlist for the two curves ? 

				
	var blendCurve = factory( 'blend', curvelist, orientlist , 'G3', 1.18 ); //This still makes the 2 spirals.
