Spatial Corp
Spatial Corporation was founded in 1986, and had one main product: ACIS, the first commercially available 3D modeling kernel. Through subsequent years, Spatial added products to its portfolio that enabled ISVs mostly in the CAD/CAM industries, to build applications. These components included extensions and updates to the ACIS modeler, visualization products, as well as acquisitions in translator technology. A significant transformation took place at Spatial when it was purchased by Dassault Systèmes in late 2000. Spatial Corp. became a subsidiary of Dassault Systèmes. Flagship products 
 CGM Modeler - the 3D modeling kernel used in Dassault Systèmes’ 3DEXPERIENCE Platform. 3D ACIS Modeler - features an open, object-oriented C++ architecture that enables robust, 3D modeling capabilities
 3D InterOp - CAD data translation framework. 3D Visualization - the HOOPS 3D Application Framework enables the development of 3D Visualization applications with advanced 2D and 3D graphics functionality. 3D Precise Mesh - an object-based software development toolkit providing fully configurable surface and volumetric meshing capabilities. Constraint Design Solver (CDS) - provides variational constraint solver solutions for design and engineering applications. References
