Design and Concept Modeling

Our vision from the beginning was to bring 3D to everyone by providing a simple, fast, flexible design tool. We believe a 3D tool should be so simple, anyone can learn it quickly and have fun while doing so. SpaceClaim is a fully functioning CAD tool that is powerful enough for rapid concept modeling, yet easy-to-use for creating detailed parts, assemblies and drawings.

You can imagine, design, create and realize your ideas faster with Ansys SpaceClaim.

SpaceClaim helps you visualize, communicate and evaluate designs in 3D so you can achieve new levels of innovation through product design and development. Whether a non-CAD expert or seasoned CAD professional, the SpaceClaim user interface allows you to refine and optimize concept models before locking down the design in a traditional CAD package.

While traditional/history based modeling tools are important, the constraints used in these tools become troublesome in the initial concept design phase of product development. SpaceClaim frees you from the constraints of history-based concept modeling, allowing you to focus on the creative process and not on the technology. With an expanded use of 3D in this early modeling phase, as well as throughout the entire product design and development workflow, you can increase your innovative ideas while also increasing productivity.

Design and Concept Modeling


For reverse engineering, SpaceClaim is unmatched in terms of power, ease of use and flexibility. Intuitive tools function to rapidly and easily convert any faceted data to surfaces or solids for downstream use. Regardless of the scan integrity, any STL file can be rapidly converted to a solid CAD format.

A groundbreaking tool, Skin Surface, offers a powerful method for autosurfacing to surface or solid geometry from prismatic or organic shapes. You can now push the boundaries of what was previously feasible and rapidly reconstruct surface data around scans of complex shapes like living organisms. The Skin Surface tool can also be used to reconstruct fixtures or jigs around faceted data, or to modify geometry of things like worn-out parts.

Facets to CAD

3D Printing

SpaceClaim’s intuitive interface allows you to create, edit, and prepare models for 3D printing faster and more efficiently than before. With the STL Prep module (faceted data toolkit), you can work directly with STL files, as well as leverage automated prep tools for 3D printing applications.

Intuitive workflows inquire of a faceted file’s integrity and further repair the file to a printable model. Regardless of the imperfection, such as overlapping and intersecting or over-connected triangles, SpaceClaim's tools will rapidly and automatically repair all STL bodies so they are print-ready.

Solid-like operations help you ensure your faceted data is just the way you want it. Use familiar manipulation tools like pull-and-move, to edit a collection of facets and change the form of the model. Boolean tools let you add or subtract surfaces or solid data from the faceted model, giving you further freedom to rapidly make changes.

With optimization tools, you can smooth facets and reduce noise from a course scan of an object. Shelling and infilling help balance the strength-to-weight ratio, while minimizing material consumption. Additionally, a series of analysis tools helps ensure your model has adequate wall thickness and overhang protection in critical areas.

The hybrid nature of SpaceClaim's STL Prep module means you can combine the best of solid modeling techniques and the flexibility of its STL editing tools. You can choose which tools will get you to the optimized result you desire.

Algoryx Momentum Add-In

Designer-focused motion-dynamics system
To create great products with complex mechanical systems, the designer must verify and visualize the form, function and performance of the dynamic behaviour. Algoryx Momentum allows the motion of large real-world geometry to be rapidly simulated and interrogated, within SpaceClaim’s fast conceptual design environment.

You will be amazed at the ease and speed with which assemblies can be set-up and simulated based on full resolution 3D CAD models. Any engineer can take an existing CAD assembly or rapidly create new geometry and have full motion dynamics running within minutes.

Even with the most complex problems, engineers can rapidly evaluate and analyze moving paths, velocities, forces and moments. This is critical within the conceptual design phase of involved systems, providing the best solution to make correct design choices as early as possible, which reduces lead times and minimizes real-world testing requirements.

Assembly bodies can be interconnected using all the joints and 3D contacts that define your engineering solution. A powerful constraint detection tool automatically adds physical joints to your model as implied by the geometry. Accurate 3D contact detection is fully automated and then used by the physics engine to get correct contact forces to maintain non-penetration conditions. To describe the specific behavior of the joints, properties such as stiffness, damping, and friction are defined as well as motors and controllers. Within seconds the motion of the multibody system can be simulated, analyzed and optimized the way it was actually designed.

Python scripting is embedded so that you can express novel physical concepts, develop control systems and further grow your team’s competitive advantage.

Model Repair

Many CAD tools output corrupt 3D data that are in desperate need of repair. No matter the task — importing models for a new design, or generating toolpaths on a solid body or high-quality meshes for simulation — the input requirement of clean geometry is still the same.

SpaceClaim's automated repair tools are designed to target problem areas of any model and provide instant options for healing and repair. Whether a model is full of holes, gaps or corrupt surfaces, these tools quickly recreate models to their intended state. Spellcheck-like tools provide feedback on location and possible remedies, but you always have the option of accepting automated repairs or providing further control of surface contours or repair types. The end results are clean surfaces and watertight solids for the next step in the engineering process.

Model Repair

Model Prep for Manufacturing

Whether you are establishing toolpaths on 3D geometry or constructing assembly fixtures for complex models, SpaceClaim is the best solution to help you increase productivity and complete your CAD/CAM projects more smoothly. Traditional history-based CAD software was developed for design engineers to create detailed models and associated documentation. When it’s time to make parts, however, its complicated constraints and internal dependencies can get in the way of getting the job done. If the designs aren’t right, it can be difficult to make changes on-the-fly. SpaceClaim makes it easy to fix problems and confirm changes with the customer.

SpaceClaim is designed to let you create, edit or repair any 3D CAD data. SpaceClaim’s unique user interface enables you to work in 3D, but it is not a lifestyle tool like complex CAD systems. SpaceClaim's automated repair tools are ideal for turning corrupt or incomplete data into usable surfaces or solids for downstream CNC use. You can focus on the toolpath creation of a model since SpaceClaim will automatically heal disjointed surfaces and repair things like holes and gaps. The versatile tools of SpaceClaim let you rapidly extract geometry necessary for fixturing or tooling of any object. Use these same tools to construct solids or even extend surface edges for adequate runoff in various manufacturing operations.
