ANSYS is specialized in developing software for product development simulation and analysis, and has sold a version of SpaceClaim (named ANSYS SpaceClaim Direct Modeler) as an option for its CAE software since 2009.

On April 29, 2014, technical software company ANSYS (NASDAQ: ANSS) acquired SpaceClaim for $85 million in cash, plus considerations.

On July 21, 2009, SpaceClaim announced support for multi-touch hardware. On September 30, 2008, Chris Randles become CEO and Mike Payne become chairman of the board. On April 1, 2007, SpaceClaim released SpaceClaim 2007 Professional, its first commercial release. Mike Payne was previously a founder of PTC and SolidWorks. In September 2005, Mike Payne, Danny Dean, David Taylor, and Blake Courter founded SpaceClaim Corporation. These functions were developed in the modelling kernel ACIS licensed to SpaceClaim by Dassault Systemes. Combine performs boolean and splitting operations, such as merging parts and subtracting parts from each other.SpaceClaim Engineer also includes more specialized tools for model preparation. Popular uses include deleting rounds and holes from a model. Fill primarily removes geometry from a part by extending geometry to fill in the surrounding area.Move repositions components and geometry, and can also be used to create patterns (often called arrays).For example, using the Pull tool on a face by default offsets the face, but using the Pull tool on an edge rounds the edge. Pull contains most creation features found in traditional CAD systems, determining its behavior through users’ selection and though the use of secondary tool guides.SpaceClaim's 3D direct modeling technology is primarily expressed through its user interface in four tools: pull, move, fill, and combine:
