Hi James, oops try with a script: in the front like this:

script:var curves = moi.geometryDatabase.getSelectedObjects();
var orientations = moi.geometryDatabase.calculateCurveOrientations( curves );
for ( var i = 0; i < orientations.length; ++i ) { orientations.item(i).flipped = false; }
var factory = moi.command.createFactory( 'blend' );
factory.setInput( 0, curves );
factory.setInput( 1, orientations );
factory.commit();
