The purpose of this exercise is to deduce the appearance of one or two hidden faces of the Block Diagram given two or one visible faces. The underlying intent is to gain an appreciation for and skill in the puzzle solving aspect of structural geology. You can do this alone or with a friend.
1) Have a couple pieces of paper or cardboard handy.
2) Open a "mystery" document from the disk or have your friend create a "mystery" block.
3) Hide everything on the screen except for one or two faces of the Block Diagram (this window will take care of the dialogs and history window). The paper is good for covering the faces.
4) Given the one or two visible faces of the Block Diagram, what do(es) the other face(s) look like? What are the structural processes that produced the Block Diagram? How many different solutions to the puzzle are there? Draw all the possible solutions graphically and parametrically.
5) Vary the parameters or structure and try again.
• As you get better at this, try superposing two or three structures. If you need it, use the History window for clues about the structural make-up of the Block Diagram.
