Here’s the quick explanation of Issues – someone might be interested to explain?
I created few Reference Line - slightly cure see the Image001 and when I select the reference line few of them have a rotation angle, How Do I fix them compare to others? – Then when I created the form I have the worst result with edges which was not expected Image002 will explain – the result in image003 with pattern. And when just copied the reference lines the Image004.
