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.^{[citation needed]}

Spatial was purchased by Dassault Systèmes in late 2000 and became a subsidiary of Dassault Systèmes.^{[citation needed]}

Flagship products

Among the company's flagship products are the following programs.

• 3D ACIS Modeler^[1] - features an open, object-oriented C++ architecture that enables robust, 3D modeling capabilities.^{[citation needed]} It is a geometric modeling kernel that was developed by Spatial, and is used in industries such as 3Danimation, shipbuilding, and computer-aided design.^[2]

• CGM Modeler^[3] - the 3D modeling kernel used in Dassault Systèmes’ 3DEXPERIENCE Platform.

• 3D InterOp^[4] - CAD data translation framework.

• 3D Visualization - the HOOPS 3D Application Framework^[5] enables the development of 3D Visualization applications with advanced 2D and 3D graphics functionality.

• 3D Precise Mesh^[6][7] - an object-based software development toolkit providing fully configurable surface and volumetric meshing capabilities.

• Constraint Design Solver (CDS)^[8] - provides variational constraint solver solutions for design and engineering applications.
