Spatial Corporation was founded in 1986, and had one main product: ACIS

ACIS

The 3D ACIS Modeler is a 3D modelling kernel owned by Spatial Corporation . ACIS is used by many software developers in industries such as computer-aided design , Computer-aided manufacturing , Computer-aided engineering , Architecture, engineering and construction , Coordinate-measuring machine...

, the first commercially available 3D modeling kernel. Through subsequent years, Spatial added products to its portfolio that enabled ISVs mostly in the CAD/CAM

Cam

A cam is a rotating or sliding piece in a mechanical linkage used especially in transforming rotary motion into linear motion or vice-versa. It is often a part of a rotating wheel or shaft that strikes a lever at one or more points on its circular path...

 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

Dassault Systemes

Dassault Systèmes S.A. is a leading company specializing in 3D and PLM software.Dassault Systèmes develops and markets PLM application software and services that support industrial processes and provide a 3D vision of the entire lifecycle of products from conception to maintenance to recycling...

 in late 2000. Spatial Corp. became a subsidiary with the backing of an established market leader in 3D design and product lifecycle management (PLM).
