Step 15 of this model. Where the heck is the reference point? I don't know what angle these 2 creases need to be.

Also, you should keep in mind when posting requests like this, to tell where the diagrams are (in Tanteidan Convention Book 10 for this model). It makes it easier for people who want to help you.
