This has been among my first attempts to do a CAD-based building instruction. The instuction is done via the utterly great software programs: Ldraw, MLCad, PovRay3.5 and LPub. Since this has still been not much more than just a test run, the featured model is really primitive. This model is aiming at a builders age of maybe 6 years (In fact I did it for my four and seven year old nephews). Instructions for models with exhaustive use of more advanced building techniques (like the SNOT and SNIR technique) are to be found for the BR23 steam and some others. Leg Godt!
