NOTE: G1BC IS NOT READY FOR DOWNLOAD YET.
G1BC is a graphical building design tool for Skyscraper that is designed to be a step up from Beno Building Creator. It is coordinate-based, which allows for walls of any size, height, and angle compared to BBC's full-height, 90-degree walls.
G1BC is currently in early development. The development team (gooper1 and elevescalators) are aiming for a beta release date in mid- to late-2012.
