- 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.
