DesignSpark Mechanical is a free 3D CAD (computer-aided design) solid modeling software

DesignSpark Mechanical enables users to solid model in a 3D environment and create files for use with 3D printers. Using the direct modelling approach, it allows for unlimited and frequent design changes using an intuitive set of tools. This free 3D CAD software is offered as a payment free download, but requires a one-time registration with to receive the latest community news and product promotions.


DesignSpark Mechanical is based on the SpaceClaim Engineer application and is the product of a collaboration between RS Components and SpaceClaim Corporation. An introductory brochure is available here. The goal to offer a free 3D CAD software with many features of high-end software is to engage with those who perhaps do not require or who cannot afford premium branded 3D CAD software, such as Engineering Students or small businesses.

Rapid prototyping[edit]

DesignSpark Mechanical supports the idea of Rapid Prototyping through SpaceClaim's 3D direct modelling methodology using the Pull, Move, Fill and Combine tools that allow a user to interact with digital 3D objects like modelling with clay, all available in the free 3D CAD version.

3D CAD library[edit]

3D models for more than 45,000 products from the RS catalog are available for download within the software[1]
