I hope someone can help me out:
I am trying to draw a cube, of which the side panels are made up in the golden ratio. Problem is, it doesnt add up in the end, as you can hopefully see in the red cricles in the picture. So i want to turn the yellow marked area a little steeper, while the green marked should remain horizontally only moving to the right a nutch. The blue side panel to wich the green is to be aligned with is scaleable. But how can i turn the yellow area, with the green area atached to it and simultaneously scale the blue panel a little bigger so that in the end green and side area share the same corner? the black marked edges indicate that they can not be changed in length. The arrwos are trying to indicate what i just tried to explain.
I hope i could make myself clear. help would be hugely appreciated.
