How do I solve the ventilation blueprints in Haven?

I found a video walkthrough of it.

Pink dot goes in the upper right with the square in the corner covering the protruding square on bottom right.

Yellow square goes all the way in the upper left.

Blue arrow/corner thing goes in the very bottom right.

Green triangle goes on the left, farther out and below the yellow square.

Move those around in the general area I indicated until it sticks and turns green to show you've got it in the right place.
