how to display Diagonal grid angle with paneling tools

Hello, there...

I'm really beginner for grasshopper, so I have no idea how I can complete this mission like attached file.

Of course, I learn panneling tools and tree algorism from this grasshopper staffs with video lecture since 2 weeks before. But I couldn't.

I have 2 problems. First , I made up right 2 sides...But left sides and upper and below things  I couldn't...anyway, I thouht I used negative integer in relative tree, that made some trouble.

Second, I couldn't do anything in the  whole right end part.

Is there anyone who can help me... T.T
