SpaceClaim is a pretty unique 3D modeling software that’s really changed how engineers handle design, mostly thanks to its direct modeling tech. Instead of sticking to those old feature-based rules, SpaceClaim lets you manipulate geometry quickly, so you can develop concepts without getting bogged down.
SpaceClaim, originally built by SpaceClaim Corporation and later picked up by ANSYS, is a solid modeling CAD tool for Windows. Engineers who need fast 3D designs often reach for it.
The big thing here is direct modeling. You can just grab geometry and change it—no need to fuss with feature trees or annoying constraints that tend to break in other CAD programs.
Engineers use SpaceClaim for geometry cleanup, model prep for simulation, reverse engineering, and even 3D printing. It opens models from almost any other CAD software, so collaborating across platforms is pretty painless.
The interface is all about simplicity. You get core tools like Pull, Move, Fill, and Combine—they let you tweak faces, edges, and surfaces without much hassle.
You can sketch 2D profiles and turn them into 3D shapes in just a few clicks.
SpaceClaim works hand-in-hand with ANSYS simulation tools. This tight integration makes it a favorite for prepping geometry before running finite element analyses.
SpaceClaim Corporation started developing the software in Concord, Massachusetts. The team wanted to offer something easier than the usual feature-based CAD systems that can be, well, kind of a headache.
When ANSYS acquired SpaceClaim, they wanted to boost their simulation preprocessing. That move brought SpaceClaim’s direct modeling into the ANSYS world as Discovery SpaceClaim.
With Version 19.0, SpaceClaim really set itself apart in direct modeling for 3D. It became known for fast concept design and easy geometry tweaks, and lots of industries took notice.
The developers built SpaceClaim for engineers who want to focus on their actual work, not on learning complicated software. That’s why its tools feel so natural when you’re working with 3D geometry.
Over time, SpaceClaim has leaned into collaboration for mechanical design and manufacturing. It helps manufacturers develop products quickly and without breaking the bank.
Direct modeling is the backbone of SpaceClaim. You can edit geometry right away—no parametric constraints or feature histories required.
The whole “pull and move” idea is central. If you see a face, just pull it to change the shape. Need a new face? Draw an edge or copy one that’s already there.
SpaceClaim sidesteps those rebuild errors that haunt feature-based systems. You can open and edit imported geometry, even if you have no clue how it was originally built.
All geometry, whether you made it in SpaceClaim or brought it in, gets treated the same. That means you can edit complex assemblies from different sources without extra steps.
Sketch-based creation is straightforward. Sketch a 2D profile, pull it into 3D, and you’re off. The software manages geometric relationships for you—no need to set up constraints.
Most design work happens by moving faces around. Push, pull, twist, blend—whatever gets you to the shape you want. SpaceClaim keeps everything solid and watertight as you go.
SpaceClaim goes a different route from traditional CAD. It skips the complex sketches and constraints, letting you jump straight into geometry manipulation. The interface is streamlined, and everything feels pretty intuitive.
SpaceClaim’s direct modeling tools really flip the script compared to parametric CAD. You don’t have to build up a bunch of sketches or define relationships before you start editing.
You can open models from just about any CAD system and start making changes right away. Got a STEP or IGES file? Just pick surfaces or edges and modify them—no need to decode the original designer’s intent.
Because changes happen in real time, you see updates instantly. Push, pull, reshape—SpaceClaim keeps everything solid under the hood.
The software handles big assemblies without slowing down. Its direct modeling algorithms chew through complex geometry, which is a relief if you’ve ever watched parametric CAD grind to a halt.
SpaceClaim is also a go-to for reverse engineering. You can import scanned data or point clouds and turn them into solid models without recreating every parametric feature.
The heart of SpaceClaim’s editing comes down to four main tools. They work on any geometry, no matter which CAD system created it.
With the Pull tool, you just select faces, edges, or surfaces and drag them wherever you want. No sketches or constraints needed.
Move operations let you shift features or partial geometry around. The tool keeps things connected, but you’re still free to position elements however you like.
The Fill tool comes in handy for removing stuff you don’t need—holes, fillets, odd details. It’s especially useful when you’re prepping models for manufacturing or cleaning up imports.
Combine operations merge bodies or split up complex parts. Boolean operations happen smoothly, and your solid stays intact.
You’ll often use these tools in a row to tackle more complicated edits. In traditional CAD, those changes would take forever.
SpaceClaim’s interface borrows from Microsoft’s design but adds its own CAD twists. The ribbon toolbar keeps tools where you can find them, not buried in endless menus.
Context-sensitive menus pop up based on what you select. Click a face, and you’ll see face tools—no hunting required.
Dialog boxes and property panels stay to a minimum. Most changes happen right on the model with visual feedback, so you’re not stuck typing numbers.
Smart selection tools help you grab related geometry fast. Pick a feature, and connected pieces highlight automatically.
SpaceClaim even bakes in KeyShot rendering. You can assign materials and create photorealistic images without jumping to another app.
The workspace shifts to match your task. Design mode brings up creation tools, and simulation prep mode puts analysis tools front and center.
SpaceClaim connects directly with ANSYS simulation software, making 3D modeling and simulation prep feel like a single workflow. Engineers can get complex models ready for structural analysis, thermal studies, and all sorts of aerospace simulations.
ANSYS SpaceClaim is built for simulation prep and geometry editing. Engineers get easy-to-use tools to tweak CAD files—even if they don’t have the original design history.
It handles tough geometry changes that parametric CAD just can’t manage. Engineers can defeature parts, fill holes, and simplify assemblies fast. SpaceClaim opens nearly any CAD format and gets models ready for meshing.
Reverse engineering is another strong suit. You can work with 3D scans or legacy designs by importing STL files and converting them into solid models fit for simulation.
Material properties and rendering details move smoothly between SpaceClaim and ANSYS. That way, you don’t lose important simulation setup info during geometry changes.
ANSYS Workbench launches SpaceClaim automatically when you need to edit geometry. You can import SCDOC files or build new models right in the integrated environment.
The SpaceClaim Link keeps active sessions connected to ANSYS Electronics Desktop. This lets you browse and pull SpaceClaim geometry straight into your simulation project.
Parameter sync is built in. Design parameters, units, and constraints carry over from SpaceClaim to ANSYS. You can even create parametric studies using variables set up in SpaceClaim.
When you update geometry in SpaceClaim, those changes show up in your ANSYS project thanks to the User Defined Model system. No more manual file transfers or extra steps.
Project archiving grabs all your SpaceClaim files automatically. Teams can share full simulation packages without losing links or parameters.
SpaceClaim packs tools that help models mesh and analyze properly. You can suppress physics objects to focus on key components while keeping the assembly context.
Healing tools catch and fix geometry problems that mess up meshing. SpaceClaim finds and repairs gaps, overlaps, and other issues automatically.
Body extraction lets you split solid and surface bodies for different analyses. You can pull out fluid domains, structures, or thermal interfaces as needed.
If you need to change how geometry links to simulation, the Break Connection feature turns linked SpaceClaim geometry into imported objects. You keep all your edits but drop the parametric ties.
Custom wizards walk you through simulation workflows inside SpaceClaim. Even if you’re not a CAD expert, you can prep models for ANSYS without getting lost.
SpaceClaim works with more than 30 file formats for import and export. It plays nicely with all the big CAD systems, using both native files and standard industry formats.
SpaceClaim handles native CAD files like SolidWorks, Inventor, Pro/ENGINEER, Unigraphics, CATIA, and Rhino. You can open these files directly, no conversion needed.
Neutral formats keep things flexible across platforms. STEP, IGES, and ACIS work between different CAD programs. STL is there for 3D printing, and JT Open lets you share with manufacturing systems.
Import Capabilities:
Export Options:
SpaceClaim keeps geometry IDs intact during import and export. That makes sure references stay put when you move files between programs.
SpaceClaim opens big-name CAD files with full relationships. Inventor assemblies keep their structure. Pro/ENGINEER and Unigraphics files bring in feature history when possible.
CATIA V5 files keep their geometry precise. SolidWorks parts and assemblies come in with materials and appearances. Rhino files import with full NURBS support.
If you’re missing components in an assembly, SpaceClaim prompts you to find them. External references update automatically if files move.
The software preserves mirror relationships and component structures on export. Hidden geometry goes out with the right line weights. Assembly hierarchies transfer cleanly.
File compatibility covers several versions. You can import CATIA V4 through V6, and SolidWorks files from 2001 onward just work.
You can drag and drop files right into SpaceClaim to import them. The software shows import progress and flags any geometry issues in the status log.
Import Process:
To export, just save your SpaceClaim document, then use Save As to pick your output format.
Export Configuration:
If you want, SpaceClaim cleans up geometry during export. It can remove imprinted edges and fix split curves, making downstream work easier.
Batch operations let you process whole folders of files at once. No need to handle each one by hand, which saves a ton of time on big projects.
Engineers depend on specialized tools to turn raw geometry into models ready for manufacturing. They use SpaceClaim to fix broken surfaces, convert scanned data, and tweak designs for whatever production method is on deck—whether that’s repairing damaged CAD files or prepping for the next big project.
When engineers import CAD files from various modeling software, geometry repair tackles the usual headaches—missing faces, overlapping surfaces, or annoying gaps that make models impossible to use for manufacturing or simulation.
With Pull tools, you can offset, extrude, or tweak existing faces without starting from scratch. The select function pinpoints the trouble spots—vertices, edges, or surfaces that need some love. Cross-section editing lets you dive in and fine-tune internal geometry with precision.
Fill operations step in to patch holes by stretching nearby surfaces across gaps. This works if the area is fully enclosed by other surfaces. If a face is damaged, the Replace function swaps it out for a fixed one, keeping the overall model structure intact.
Surface healing jumps in to turn connected faces into solid bodies. The software figures out if it’s dealing with open surfaces or closed volumes and treats each accordingly.
| Tool | Primary Function | Best Used For |
|---|---|---|
| Pull | Modify face geometry | Extending surfaces, creating features |
| Fill | Patch missing surfaces | Closing holes, completing models |
| Replace | Swap damaged geometry | Fixing corrupted faces |
| Move | Reposition elements | Aligning components |
Reverse engineering takes real-world objects and turns them into digital models by scanning and rebuilding. When you get point cloud data from a 3D scanner, it usually needs a lot of work before it’s useful CAD geometry.
Engineers start by importing the scan and picking out the surfaces that define the object’s main features. Sketching tools help create reference geometry, guiding the surface reconstruction. The software converts closed sketch regions into faces you can pull and shape.
With Tweak face functions, you can reshape surfaces to match the design you want instead of copying every scan bump or flaw. This comes in handy when the scan data is noisy or incomplete. Bend operations let you adjust curves to hit your specs.
Block recording keeps track of each step, so you can replay successful workflows with similar objects. That saves a lot of time when you’re processing batches.
Mesh-to-solid conversion demands a careful eye for surface quality and smoothness. Engineers check that the rebuilt geometry meets manufacturing tolerances before moving on to production planning.
Manufacturing optimization makes sure your models are practical to produce with the tools and materials you’ve got. Each production method comes with its own geometric quirks and rules.
For 3D printing, mesh repair tools clean up non-manifold edges and self-intersections. Planning support structures means you have to look for overhangs and bridge spans. Wall thickness checks help you avoid print failures due to thin spots.
Sheet metal work needs special edge treatments and bend allowances. The software calculates flat patterns from folded parts, adjusting for material and tooling quirks.
Component organization breaks down complex assemblies into pieces you can actually manufacture. Cutting tools help split big models into printer-sized chunks or add assembly joints.
Quality validation runs automated checks to catch manufacturing issues early. Gap detection spots spacing problems between parts. Volume calculations help you keep material use in check.
Export functions keep your models intact across all the file formats manufacturing equipment needs. STL files hold onto mesh detail for 3D printing, while STEP files keep parametric data for CNC jobs.
SpaceClaim helps manufacturing teams with direct modeling tools that speed up geometry creation, prep workflows, and design tweaks. Engineers lean on this software to push products through development faster and skip the old CAD bottlenecks.
SpaceClaim makes concept development quick and painless with its direct modeling approach. Engineers build 3D models fast, without having to wrestle with classic CAD systems.
The software turns 2D sketches into 3D geometry with minimal fuss. Teams import all sorts of file types and churn out 3D-ready data using familiar routines.
Design flexibility means you can edit geometry however you want, no matter how the model started out. That’s a lifesaver when you’re working with files from other CAD systems.
SpaceClaim links up with Ansys Workbench for parametric modeling. Change a parameter and see the update ripple through integrated simulation environments.
It’s a standout for reverse engineering too. Teams convert STL scans to CAD and rebuild surfaces—even around tricky organic shapes.
Ansys SpaceClaim slashes the time it takes to prep models for simulation. Engineers can simplify complicated geometry for analysis in just minutes.
The software de-features CAD models by stripping out tiny details that bog down simulations. You get clean, streamlined geometry that’s ready for finite element analysis.
SpaceClaim can pull out fluid domains from solids automatically. Engineers working on CFD projects get smoother geometry prep and less hassle.
Model repair tools fix broken or incomplete geometry before you run simulations. The software closes gaps and heals surfaces that could trip up your analysis.
It integrates tightly with Ansys simulation tools. You can tweak geometry in SpaceClaim and see those changes update instantly in your simulation model.
Manufacturing teams use SpaceClaim to whip up jigs and fixtures quickly. The software grabs geometry from existing parts so you can design custom tooling.
Automated repair tools turn incomplete manufacturing data into usable surfaces. Machinists can finally work with files from all over, no matter the original CAD system.
SpaceClaim handles sheet metal jobs well. Engineers unfold parts with a click and check both folded and flat states side by side.
The software preps models for 3D printing using dedicated STL modules. Teams repair files and optimize geometry, even if the data was a mess to start with.
SpaceClaim makes manufacturing prep easier by converting multiple file types into machining-ready geometry. Engineers focus on toolpaths, while the software cleans up the rest.
SpaceClaim acts as the bridge between design ideas and simulation analysis, offering quick geometry prep and fast model edits. The software cuts out the typical delays that slow engineering teams from tweaking designs to running final analysis.
SpaceClaim really shines when it’s time to clean up CAD models for simulation. Engineers often get stuck with gnarly geometry files full of useless details or errors that block meshing.
The software strips out clutter automatically. Tiny holes, unnecessary fillets, and fussy features that don’t help simulation accuracy get cleaned up or tossed. This cuts down computational load without hurting results.
Common geometry prep tasks:
SpaceClaim takes in geometry from any CAD system. Because it’s direct modeling, you don’t need the original design intent or feature history. Surface repairs happen with simple pull and move actions, not by wrangling a complex feature tree.
Multi-part assemblies get handled fast. You can combine, split, or tweak components without messing up other parts. That flexibility is a big deal when simulation needs don’t match the original design.
Design cycles move way faster when SpaceClaim is plugged into simulation workflows. Engineers edit geometry right inside the simulation setup—no more bouncing between different software.
You can make real-time design changes during analysis setup. Load points, boundaries, and contacts update on the fly as you tweak geometry. That cuts out the normal back-and-forth between design and analysis teams.
Ways simulation workflow speeds up:
SpaceClaim’s faceted geometry support helps with additive manufacturing. STL files from scans or topology optimization convert to solids for simulation. That means you can check part performance before you even print.
Concept modeling lets engineers build simplified versions of big systems. These models focus on the main load paths, saving time and computing power.
Simulation teams work faster when geometry prep isn’t a nightmare. SpaceClaim removes the need for deep CAD expertise for model edits and repairs.
Non-expert users get guided wizards for powerful geometry editing. Step-by-step simulation help walks you through prep without needing to master the software. This opens up geometry editing to more team members and keeps projects moving.
Big productivity wins:
Analysts work independently from design teams for small geometry changes. Need to add a sim-specific feature or remove excess detail? Do it right in the simulation tool. That autonomy speeds up projects and cuts down on back-and-forth.
The software keeps the original design intent safe while allowing simulation-focused edits. You get separate versions for simulation without touching the original CAD—no more fighting over design vs. analysis needs.

SpaceClaim comes in several license types, from basic Discovery to full Mechanical Enterprise, and it really wants a Windows system for best performance. You can override license preferences and need to meet certain hardware specs for smooth 3D modeling.
SpaceClaim supports eight license configurations for different engineering needs. disco_level1 (Discovery) and a_spaceclaim_dirmod (SpaceClaim Direct Modeler) are the main ones.
By default, the software checks for Discovery licenses first, then Direct Modeler. You can flip this order with the ANS_MODELER_FLIP_LICENSE environment variable set to 1.
Other license options:
To override license preferences at startup, use the /p command line option. For example, SpaceClaim.exe /p=ansys launches with Mechanical Enterprise licensing.
SpaceClaim runs only on Microsoft Windows operating systems. You need Windows XP with Service Pack 3 or a newer version.
It works on Windows Vista and Windows 7 too. Most people these days install it on Windows 10 or Windows 11.
If you use macOS or Linux, you’re out of luck unless you set up virtualization or dual-boot. The software just doesn’t run natively on those platforms.
System admins really need to check which Windows version they’re using before installing. Keeping Windows updated goes a long way toward smooth performance and better security.
You activate your license with either a serial number or a license file, depending on how you bought it. Node-locked licenses keep the software tied to one machine for security.
To register a new license, head to the SpaceClaim Options License screen. You’ll have to remove any old license before you can add a new one.
If you’re using a floating license, you need to set the SPACECLAIM_LICENSE_FILE environment variable. That tells the software where to find your network license server.
A lot of install problems come from missing environment variables or a misconfigured license server. The FloatingLicenseConfig.exe tool usually sets up those system variables for you during installation.
Ansys SpaceClaim started as a bold CAD startup that shook up the industry, and now it’s become a staple in engineering workflows. By 2027, it’ll fully transition to Ansys Discovery.
The journey so far has brought some big tech leaps and strategy changes. Engineers have had to rethink how they approach 3D modeling because of these shifts.
SpaceClaim first hit the scene in 2005 with its direct modeling approach. That move challenged the old-school parametric CAD systems.
Engineers finally got a tool that let them tweak 3D models without getting tangled in design history. It was honestly a breath of fresh air.
They added live simulation and better file compatibility in later versions. The platform started supporting more CAD formats but kept its easy-to-use interface.
Performance got a boost too. The software started using GPUs better and rendering models faster.
Memory management improved, so users could work with bigger assemblies without much hassle. It really made a difference for larger projects.
SpaceClaim integrated with simulation tools, which made it a solid choice for preprocessing workflows. Users could prep complex geometries for analysis without bouncing between programs.
The latest updates focused on collaboration features and cloud support. Distributed teams can finally work together more smoothly.
Ansys moved SpaceClaim into maintenance mode starting with version 2023 R2. By 2027, they’ll discontinue it completely.
They’re nudging everyone toward Ansys Discovery as the new go-to. Discovery opens SpaceClaim files (.scdoc and .scdocx) directly, so you don’t have to fuss with file conversions.
Discovery Pro (previously called Discovery Modeling) gives you more features than SpaceClaim ever did. You get live simulation for static structural mechanics, which is pretty handy.
The platform supports different license types like Mechanical PrepPost and CFD Enterprise. That flexibility helps organizations slot Discovery into their existing setups.
Right now, Discovery only runs on Windows. Ansys says Linux support is coming, but we’ll see.
For modeling, you’ll need at least a 2GB VRAM GPU, and for live simulations, 4GB is recommended. It’s not super demanding, but you do need a decent graphics card.
Discovery’s development team is working on bringing more Ansys tech into one platform. SPEOS optical simulation and Material Designer are on the integration list.
The software leans into real-time simulation, so you get instant feedback as you tweak your designs. You can see stress, temperature, and fluid flow updates in real time.
Native CAD editing with history tracking is a big leap forward. Now, you can change imported models and still keep tabs on design intent.
Enhanced workflows make it easier to move from concept to analysis. You don’t have to jump through as many hoops to get from a rough sketch to a full simulation.
Future releases will bring more materials and analysis options. Ansys is clearly pushing to make Discovery a one-stop shop for design and simulation.
SpaceClaim stands out from traditional parametric CAD systems because of its direct modeling. This gives you some neat advantages for quick design changes, but it’s not perfect for everything.
Your best choice really depends on your project needs and how experienced your team is with different CAD tools.
Direct vs. Feature-Based Modeling
SpaceClaim lets you push, pull, and reshape geometry directly. You don’t have to mess with a feature tree.
Old-school parametric CAD systems like SolidWorks and Creo force you to build models step by step with a detailed history. That’s powerful but can get complicated fast.
With SpaceClaim, you can easily edit imported geometry from any source. There’s no need to know the original design’s intent or feature order.
Design Flexibility
Parametric CAD makes you plan out features and their relationships. Changing something can mean rebuilding a bunch of stuff downstream.
SpaceClaim skips all those headaches. You make changes instantly and don’t have to worry about breaking the model.
Learning Curve Differences
Traditional CAD takes a while to learn—features, constraints, parametrics, you name it. SpaceClaim feels a lot more like common modeling tools and is pretty intuitive.
Most people get up to speed with SpaceClaim in days, not weeks or months.
SpaceClaim Advantages
It’s great for concept modeling and rapid prototyping. You can make changes on the fly without worrying about breaking references.
If you’re working with imported geometry, SpaceClaim makes it painless. You can fix, tweak, or optimize models without needing the original files.
Key Limitations
SpaceClaim doesn’t have strong parametric tools for big assemblies with lots of variations. For complex engineering calculations and simulations, you’ll still need other software.
It’s not the best for sheet metal work or advanced surfacing. Dedicated manufacturing CAD programs do those jobs better.
Performance Considerations
If you’re building massive assemblies, parametric CAD systems handle them better. SpaceClaim works best for smaller, focused projects.
Concept Development
SpaceClaim is perfect for teams sketching out early concepts or exploring lots of design ideas. You don’t get bogged down by parametric constraints, so creativity isn’t slowed.
A lot of space industry teams use it for early component design and payload studies, where speed is more important than detailed parametric control.
Reverse Engineering Projects
If you need to work with scan data or old CAD files, SpaceClaim handles it well. Teams can recreate designs from physical parts or make changes to existing components without the original files.
Model Preparation
SpaceClaim makes prepping CAD data for analysis simple. You can clean up assemblies, remove extra details, and fix geometry issues fast.
Manufacturing teams use it for tooling and fixture design, where being able to directly manipulate geometry saves a lot of time.
Space law is a tangled web of international treaties and national rules. It leaves a lot of uncertainty for countries and private companies aiming for space.
Current legal frameworks just haven’t caught up with space commercialization. They’re still trying to keep things peaceful, but it’s a tricky balance.
The 1967 Outer Space Treaty is the main law for space activities and property rights. It says no nation can claim sovereignty over the Moon, planets, or asteroids.
Basically, outer space belongs to everyone. No country can own land on the Moon or anywhere else in space.
Then there’s the 1979 Moon Agreement, which calls the Moon and its resources the “common heritage of mankind.” Only 18 countries have signed it, and the big space players—like the US, Russia, and China—aren’t on board.
Countries usually avoid making direct territorial claims because of treaty obligations. Instead, they set up operational zones around their stuff.
The US uses the 2015 Commercial Space Launch Competitiveness Act to justify resource extraction. That law lets American companies own and sell what they mine from asteroids or the Moon, but without claiming the land.
Russia has talked about similar laws for its companies. China’s national space laws also allow resource use for economic reasons.
Private companies face a lot of legal gray areas with space mining. The Outer Space Treaty says governments have to approve and supervise their citizens’ space activities.
Companies need licenses from their country before they can do anything in space. These licenses often include environmental and safety checks, plus coordination with other countries.
If something goes wrong, governments are on the hook internationally for what their companies do. That could mean claims for damages to other nations’ space assets or even personnel.
Not many disputes about space territory have made it to international courts. Most issues involve satellite interference or space debris, not land grabs.
The Antarctic Treaty System is probably the closest example for handling territory in international zones. It pauses territorial claims but allows research and peaceful activity.
International arbitration panels have handled satellite interference cases. Those rulings focus more on who can operate where, not who owns what.
The Outer Space Treaty flat-out bans national appropriation of space. No country can claim land by any method—occupation, use, or otherwise.
Countries can set up research stations or facilities on the Moon or elsewhere. But these don’t give them property rights—just operational control over their immediate area.
Article VI makes each government responsible for their nationals’ space activities, whether it’s a government agency or a private company. That means there’s accountability, but still no territorial rights.
The International Court of Justice acts as the main place where nations bring their space-related disputes. If a country thinks another has violated a treaty or just wants clarity on space law, they can take their case there.
The United Nations Office for Outer Space Affairs steps in to guide discussions about space law as it evolves. This office also helps countries coordinate their responses to new issues and questions that pop up in outer space activities.
When two spacefaring nations work together, they usually set up their own ways to resolve disputes. These agreements lay out how they’ll handle arbitration and keep their space operations running smoothly.
