The historical development of solid modelers has to be seen in context of the whole [[Computer-aided design|history of CAD]], the key milestones being the development of the research system BUILD followed by its commercial spin-off [[Romulus (b-rep solid modeler)|Romulus]] which went on to influence the development of [[Parasolid]], [[ACIS]] and [[Solid Modeling Solutions]]. One of the first CAD developers in the [[Commonwealth of Independent States]] (CIS), ASCON began internal development of its own solid modeler in the 1990s.<ref>{{cite journal

This is also when the Programming Language of Solid Modeling [[PLaSM]] was conceived at the University of Rome.
