The main wing of free flight hand launch glider has multi-stage dihedral angles, 2-stage or more.
This shape helps to design dihedral angles.

The stencil that uses macro to automatically update bounding box is available.
2 video shows how to use the shapes.

You did as usually an awesome job. Just pitty that there are so few people interested in air planes in this forum ;-)
From a pure visio side, I would have appreciated to be able to modify the formulas from both sides (results becoming the input).

Thank you for your comments.
You are right, that  was the problem I could not solve.
Not yet I don't have a solution, but have reached an idea.
"2 way" is not easy to realize because of too many parameters.
But 2 shapes can give user the different way of input.

One shape requests length and angle of wing segments for input.
And another new shape requests dihedral rate, horizontal span and break point.
I hope they help many designers of HLG.
Here is a short video that compare 2 shapes.

and here is the new stencil.

Added new video to explain 2 ways of input to 3-stage dihedral angles.
