    I am tasked to do an igloo type structure and ended up downloading all of TaffGoch's models from the 3dwarehouse including the Domebook 2 pdf. I am following the book, but I am now stumped in page 5, where there are 5 solids and I don't know how to model them manually, like laying the shapes flat then folding them into place.

    Can somebody teach me how to rotate the shapes into place so that the vertex will line up properly?

      Well you can do the cube with push/pull and if you ever passed a course in trigonometry, you should be able to create the proper constrution points using SOHCAHTOA.

        Taff runs a whole support forum for his geodesic structures (although he turns up here once in a while, too).

          I think I got it. I just made a circle that is centered and parallel to the side of the pentagon inside the group and where they meet, its the snap point for rotating the faces outside the central pentagon.

            Thanks Gaieus, I made myself a member of the group. 😄

              Hi folks.

              See this SU file for ideas.

                @Jean Lemire: very instructive!
                I function as a tester for Tgi3D so I find all sorts of strange Sketchup bugs. A few months ago I came across a SketchUp feature which could be considered a bug. Imagine you are performing a move rotate or scale operation inside a component instance, Sketchup inference engine allows you to snap on a feature in another instance of the same component (which potentially depends on the edit you are performing). You can have Sketchup solve equations for you (or draw a dodecohedron directly for that matter).
