The geometric constraint solving became necessary part of CAD systems in 80s, when Pro/Engineer firstly introduced feature-based parametric modeling concept.<ref>{{cite book|last1=Robert Joan-Arinyo|title=Basics on Geometric Constraint Solving|url=http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.331.9554&rep=rep1&type=pdf}}</ref><ref>{{cite book|title=Modelling with constraints: theoretical foundation and application|url=http://www.sciencedirect.com/science/article/pii/0010448595000232}}</ref>
There are additional problems of geometric constraint solving that are related to sets of geometric elements and constraints: dynamic moving of given element keeping all the constraints satisfied,<ref>{{cite book|title=A constraint-based dynamic geometry system|url=http://www.sciencedirect.com/science/article/pii/S0010448509000876}}</ref> detection of over- and under-constrained sets and subsets,<ref>{{cite book|last1=Rossignac|first1=Jaroslaw|last2=SIGGRAPH|first2=Joshua Turner, editors ; sponsored by ACM|title=Proceedings : Symposium on Solid Modeling Foundations and CAD/CAM Applications, Radisson Plaza Hotel, Austin, Texas, June 5-7, 1991|date=1991|publisher=Association for Computing Machinery|___location=New York|isbn=0-89791-427-9}}</ref><ref>{{cite book|title=Extensions of the witness method to characterize under-, over- and well-constrained geometric constraint systems|url=http://www.sciencedirect.com/science/article/pii/S0010448511001606}}</ref> auto-constraining of under-constrained problems, etc.
