ANSYS SpaceClaim is a multipurpose 3-D modeling application providing efficient solutions to common modeling tasks. Built on the direct modeling technology, SpaceClaim removes geometry problems associated with various 3-D CAD operations, such as design or concept modeling, repair of translated CAD files, general model defeaturing, and complete model editing. With it’s premise of ease of use and simplicity, you’ll find SpaceClaim to be extremely valuable in tackling small to large modeling problems.

A new way of 3-D Modeling
SpaceClaim’s unique user interface, modeling technology and versatile toolset enables you to easily create and modify geometry without the complexity associated with traditional CAD systems. When working with existing CAD models, you can de-feature and simplify geometry with automated, easy-to-learn tools. SpaceClaim is ideal for engineers who don’t have time for heavy CAD tools but want and need to get fast answers using 3-D.
