Discovery SpaceClaim 3D CAD Direct Modeler

Freedom to Create, Edit, and Repair 3D Models

ANSYS Discovery SpaceClaim is a multipurpose platform for providing efficient solutions to common 3D CAD modeling tasks. It makes it easy for anyone to create, edit, or repair geometry without worrying about the underlying technology.

The direct modeling methodology frees you from the constraints of traditional concept modeling. Focus on the creative design process and not on the technology. SpaceClaim removes geometry problems associated with various 3D CAD operations including:

  • Design or concept modeling
  • Repair of translated CAD files
  • General model defeaturing
  • Complete model editing


Advantages to using Discovery SpaceClaim compared to other CAD modeling software

Discovery SpaceClaim is an extremely cost-effective solution for tackling small to large modeling problems. It’s reasonably price at a fraction of the cost of traditional parametric CAD modeling package. Finish projects faster and cheaper in the market.

Do It Faster

Quickly create, edit, or repair 3D CAD or faceted file types. Import and integrate any geometry in one environment, no matter the origin (suppliers, in-house library, or online resources). Easily share your ideas with customers, R&D engineers, CAE analysts, team members, and manufacturing.


Regardless of the modeling task or your formal training, Discovery SpaceClaim’s unique toolset enables you to create rough concepts, detailed designs, or edit 3D data created in other CAD systems. Use the same tools to prepare models for any faceted/STL file for downstream use.

Reverse Engineering

Discovery SpaceClaim is unbeatable in terms of power, ease of use, and flexibility for reverse engineering applications. Intuitive tools rapidly and easily convert any faceted data to surfaces or solids for downstream use. Regardless of the scan integrity, any STL files can be rapidly converted to CAD format. Use intuitive and powerful tools to autosurface simple or complex mesh data, build intricate parts, or recreate fixtures quickly and efficiently.

Key features of using SpaceClaim for reverse engineering include:

  • Automatic surface fitting along facets of any STL file
  • Create and modify highly organic skinned surfaces
  • Sketch curves along the facets of an STL file
  • Easily create fixtures around faceted data
  • Rapid blending of period loops in recreating complex geometry
  • Clean up messy scans

Design and Concept Modeling

Design the way you think

Achieve new levels of innovation through product design and development. Discovery SpaceClaim enables you to easily visualize, communicate, and evaluate designs in 3D. Traditional/history based modeling tools can be restrictive and hinder the initial concept design phase of product development. SpaceClaim frees you from the constraints of history-based concept modeling to create parts, assemblies and drawings as quickly as your ideas are concieved.

Key features of using SpaceClaim for design include:

  • Full part and assembly modeling
  • Detailed drawings including full 2D/3D GD&T
  • Photorealistic rendering capabilities with Keyshot
  • Open/edit files from neutral and native CAD systems
  • Complete help guide and tutorials for a rapid start

Pushing the Boundaries of 3D Scanning Technology

Flexibility for users to easily adapt the system to fit their needs
  • rapid geometry creation

    Rapid Geometry Creation

    Discovery SpaceClaim’s streamlined tools and workflows mean you can create rough concepts, detailed designs, tooling/fixtures, CAE related geometry, or reverse engineer an STL file into a clean 3D CAD model in seconds.

  • STL file manipulation

    STL File Manipulation

    Watertight or clean STL files are easy to achieve with Discovery SpaceClaim. With faceted data editing tools, you can inquire, repair, and optimize STL files for downstream use such as 3D printing and reverse engineering faster and more efficiently than ever before.

  • model repair

    Model Repair

    Whether importing models for a new design, generating toolpaths on a solid body, or needing a high quality mesh for simulation, the input requirement of clean geometry is the same. Automated repair tools accelerate time to mesh by healing dirty and incomplete CAD files fast.

  • easy to learn tools

    Easy to Learn

    Discovery SpaceClaim is the easiest CAD tool you’ll ever learn. With only 4 tools (Pull, Move, Fill, Combine) that perform 80% of the common modeling tasks, it’s designed to be a go-to tool that anyone could begin using with minimal training.

  • CAD import and editing

    CAD Import and Editing

    Simple and powerful tools defeature both parts and assemblies prior to meshing and solving, in a fraction of the time of traditional CAD tools. SpaceClaim is built on direct modeling technology. You can defeature and edit your file without regard for rebuild errors or needing to understand how a file was initially constructed.

  • versatile


    The geometry centric nature of SpaceClaim means that the same powerful tools are used across different use cases. For example, you might use the Pull tool to create a fixture for manufacturing, but it is versatile and powerful enough to aid in the repair of geometry by extending surface bodies.
