Solid Modeling Solutions^© is your independent "Source Code Advantage" supplier for a comprehensive suite of geometry libraries for modeling BSplines, fully non-manifold solids with a powerful set of constructors and operators that support booleans, offsets, fillets, tessellations, deformable modeling, optimized shape fitting and much more. In addition to NURBS-based libraries, SMS provides a subdivision surface library and a polygon-based library.

SMLib™, TSNLib™, GSNLib™, NLib™ are a graduated set of source code libraries supporting NURBS and polygonal geometric modeling. The libraries include a comprehensive set of CAD functions from curve and surface construction, modification, and analysis to advanced operations such as booleans, fillets, tessellation, among many others.

SMLib™ Our flagship product built upon TSNLib™ provides fully functional non-manifold topological structure and solid modeling functionality including the ability to perform NURBS boolean operations, fillets, etc.

TSNLib™ Built on top of GSNLib supporting trimmed surface representations.

GSNLib™ A basic curve and surface NURBS library. GSNLib™ provides a useful interface to NLib while adding value as well. Includes curve/curve and surface/surface intersection and polygon modeling.

NLib™ A comprehensive BSpline NURBs library fully supporting curves, surfaces, and volumes with an extensive set of shape query and construction tools.

VSLib™ Provides deformable modeling as part of a library using the constrained optimization techniques of the calculus of variations. The library supports several very different geometric operations.

SDLib™ Subdivision surface source code library that creates and modifies complex shapes with hierarchical Catmull-Clark surfaces.

PolyMLib™ Polygonal based geometric modeling to repair, optimize, review and edit triangle mesh models. Analyze surface properties, repair and optimize surface meshes.

Data Translators™ NURBS based geometry translators to interface between Nlib™, GSNLib™, TSNLib™, SMLib™ and IGES, STEP, SAT, VDAFS, OpenNURBS.
