Brand new to rhino. help with aligning objects

I am an architecture student and just started using rhino. I have to model this paper diagram in Rhino 3D. what is the easiest way to do this? I tried making all the planes but i don’t know how to align them on the edges at the correct angle. The picture is a folded 11x 17 piece of paper.

.

I think it’s simplest in this case to start with the wireframe or even just the corner points, rather than trying to “fold” a surface into place. Once you have laid out all the corners, you can simply “surface” the object using the command Surface>From corner points and create the surfaces one by one. Then select all the surfaces and join.

If you create the wireframe with line segments first, you can also use Surface>From planar curves to create each triangle.

HTH,
