Had this project been pursued, Autodesk would have been able to launch, in early 1989, a 2D parametric modeling package which ran on a minimal DOS configuration and served as a conceptual modeling front-end to AutoCAD. This opportunity was passed by. Two years later, in 1990, it was suggested that Autodesk should acquire Ashlar to obtain constraint technology similar to that in Rube. At this writing, in 1993, Autodesk does not have a constraint manager in its product portfolio.
