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: SpaceClaim also licenses its software for OEMs, such as ANSYS, Flow International Corporation, CatalCAD, and Ignite Technology which markets a version of SpaceClaim for jewelry design. SpaceClaim Corporation markets SpaceClaim Engineer directly to end-user and indirectly by other channels. It was acquired by Ansys in May 2014, Inc, and was integrated in subsequent versions of Ansys Simulation packages as a built-in 3D modeler. Its first CAD application was launched in 2007 and used an approach to solid modeling where design concepts are created by pulling, moving, filling, combining, and reusing 3D shapes. SpaceClaim Corporation was founded in 2005 to develop 3D solid modeling software for mechanical engineering. The company is headquartered in Concord, Massachusetts. SpaceClaim is a solid modeling CAD ( computer-aided design) software that runs on Microsoft Windows and developed by SpaceClaim Corporation.
