'''Solid Modeling Solutions''' is a company who has an implementation of a mathematical representation of NURBS ([[Non-uniform rational B-spline]]), 3D geometry, and [[Solid modeling]] technology which emerged in the 1980s and 1990s into a commercial implementation known as SMLib (for solid modeling library).<ref>Potts Steves, Michelle and Frechette, Simon.

SMS provides source code to customers in order to enhance and enable their understanding of the underlying technology, provide opportunities for collaboration, improve time to repair, and protect their investment. Product delivery, maintenance, and communication is provided by web-based mechanisms. SMS has established a unique model of technical organization and an adaptive open-source approach. The subscription-based pricing philosophy provides a stable base of technical expertise, and it is cost-effective for its customers when viewed from the perspective of total cost of ownership of complex software.<ref>Greco, Joe.
