solvespace  has geometry and constraints engine for mechanical CAD
"The constraint solver used in SolveSpace is available separately as a library."
http://solvespace.com/library.pl     http://solvespace.com/dl/solvespace-rel2.0.zip
This package includes documentation, the library itself, and the necessary interface files to use the library with your code. 
Examples are included, in:

     C/C++ (for the MSVC++ compiler, version 6 or later)
     VB.NET (for the Microsoft .NET Framework, version 3.0 or later)

SolveSpace is distributed under the GPLv3"



The constraints engine could be used as a push to DRC limit route method.
