    How do I create such the pattern in GSD

    I know there are three choices of pattern to repeat a feature in GSD, but I couldn't create such the pattern with no one. How can I create such the hexagon pattern on the swept shape?

    Why fillet does opposite to my order

    First of all, I myself know, I created this shape out of engineering rules!

    However, please note the pictures and enlighten me, why fillet is done reversely?
