After unfolding and refolding a part (to add holes) the flat pattern is now cooked (in the image you can see the Right Plane for reference). Why is this and how can it be fixed? If I supress the unfold, cut and fold features the flat pattern is straight and parallel to the planes.
One suggestion:
You can make a new view for your flat pattern and use that in your drawing.
