The alpha version will feature the Blueprint Wizard, which automatically deconstructs a 3D structure into 2D pieces, figures out which pieces are on the same 2D plane, generates a layout of all the planes, calculates the necessary lengths and angles, and prints them on a sequence of pages. Every piece is numbered and annotated with calculated geometric information adequate to guide students to cut it from provided constructional materials such as paper or foam board. The entire deconstruction process is animated so that the user has an intuitive understanding of the relationship between a house and the pieces in the blueprint.

building shown in Figure 1.
Students also have an option of fitting designs to the dimensions of constructional materials. For example, one option is to assemble a house using printer paper. If students select this option, Energy3D will automatically rescale every piece to guarantee that the largest piece can fit an A4 page and all the others will be proportionally rescaled accordingly. In this case, the texture and all the marks on a piece will be printed out, making it possible for students to construct a physical scale model that looks just like its computer counterpart.
