Threedy releases instant3Dhub 3.11

AI for 3D data is coming to industrial workflows

This is about AI agents that can work with 3D data to handle tasks that humans currently do. Not tools that help you design faster, but agents that take on whole work steps: reviewing, interpreting, communicating, reporting. The same shift we've seen in text-based knowledge work like legal, now entering spatial data.

This matters because 3D data in industrial companies isn't just sitting in CAD tools. It moves. It goes from design to manufacturing. It goes from engineering to sales. It goes from development to the customer and back. At every handoff, someone has to translate that 3D data into something another person or team can act on. That translation work is manual, expert, and time-consuming. That's the target.

The Catena-X Geometry Kit

The Catena-X Geometry Kit is a standard for cross-company 3D geometry exchange, now part of Tractus-X. It defines how to describe, publish, and consume 3D geometry across company boundaries building on the Catena-X architecture and advantages.

Building on Catena-X, the Geometry Kit enables sharing of 3D geometry data in a dataspace between companies: a setup where multiple organizations share data in a controlled, decentralized, and interoperable way, without giving up ownership of it. The Eclipse Dataspace Connector (EDC) is the standardized interface each participant uses to communicate across that space. Geometry is published with a policy attached, scoped to a specific project and partner, with an expiry date. That policy is enforced technically, not just agreed contractually. And because it's a shared standard, there's no bilateral integration to build per partner and others can join the dataspace with low effort.

How It Works in Practice

A supplier publishes integration-relevant geometry through their Digital Twin Registry. The OEM accesses it through their own application interfaced via the EDC. When there's an update, the partner accesses the new version through the same channel. No stale copies sitting on their side to track down. When the project closes, the supplier revokes the policy and access ends automatically.

This also handles heterogeneous PLM and CAD tooling without custom integration per project. Standardized interfaces do that work once, at the infrastructure level. If a third organization needs to join mid-project, they connect to the network without requiring changes from anyone already in it.

One thing worth being upfront about: your tooling vendor needs to implement the EDC interfaces. The standard only works if the tools in the room support it.

Where instant3Dhub Fits

instant3Dhub implements the Geometry Kit on the consumer side. Geometry published via Catena-X streams directly into instant3Dhub for review, clash detection, DMU checks, and collaborative sessions across organizations, without export or conversion.

We demonstrated this end to end at the prostep ivip Symposium with Schaeffler. Try the demo in the browser. If your organization is evaluating adoption, book a call or reach out at product@threedy.io.

Introducing 3DSpaces

3DSpaces are the spatial workspace and whiteboard for enterprise 3D CAD workflows and applications. It is where teams come together to prepare, structure, and manage the context around complex data, ensuring that projects can move forward with consistency and clarity. From design reviews and ramp-up alignment to training programs, from sales to service documentation, the 3DSpace provides a durable foundation that supports both daily tasks and long-term initiatives.
With instant3Dhub 3.12, we are introducing initial 3DSpace Management to establish the 3DSpace as a persisted, reusable workspace. You can now configure and persist 3DSpaces as part of your workflows.
We’ve created an example as part of the release and are looking forward to your experiments and experiences with the 3DSpace. If you want to learn more, if we’ve gotten your neurons firing - lets talk!

3DSpace Members, Actions and Roles

As enterprises scale up their use of instant3Dhub, collaboration in the 3DSpace will become dynamic and take different forms, depending on your teams. Teams run global design reviews, remote training, and cross-department workshops. With instant3Dhub 3.12, we are introducing three foundational capabilities to give you the freedom and creativity to manage this collaboration: Members, Member Roles and Member Action. These capabilities bring clarity, structure and efficiency to enterprise 3D CAD collaboration.

Every 3DSpace participant is defined as a Member, represented with default and customizable metadata. This improves transparency during collaboration and makes it easy to understand who is present and how they can contribute.

For developers, the new MemberAPI provides programmatic access to member lists and metadata, enabling tailored workflows and dashboards. Developers can now build role-aware interfaces and adaptive UIs.

Accidental changes or miscommunication can lead to confusion in meetings or projects. To give you a head start in mapping your workflow to the 3DSpace, we are also introducing Member Roles. In this release, they do not differ in behavior but only serve as labels that you can use for dynamic UIs. In the future, we will expand this to define levels of responsibility and permissions. The 3 initial roles are Owners, Editors and Viewers.

Roles are available as part of the MemberAPI and will both streamline existing workflows and power new Use Cases. We’ve designed the system for extensibility so more roles could be introduced in future updates. We’re interested to learn what other roles you might need or if you would prefer the ability to configure custom roles and permissions.

Synchronously Collaborate by Following or Guiding other Members

Being present together in the same 3DSpace is valuable, but alignment matters even more. The new Follow/Unfollow Member Action allows participants to see exactly what another member is looking at. You can use it to e.g. build a “present to all” feature in your application.

For developers, the MemberAPI exposes follow/unfollow functions and events, so custom UIs can show who is following whom. We’re already working on a specialized jump_to_view function that can be used for momentarily jumping to the camera view of a member.

Magic Links: One-Click, Role-Aware Onboarding

Onboarding dozens of stakeholders into a 3DSpace doesn’t have to be time-consuming or complex. With 3DSpace Magic Links, Developers can now generate links that automatically assign the correct role when someone joins. This allows large groups to enter effortlessly with the right role and context instantly.

Early Customer Feedback

“Working together in the 3DSpace is making a lot of preperation and after-work redundant. Everyone gets access to the data in advance and our meetings now flow more efficiently. Follow mode has made our design reviews much smoother. Instead of spending minutes aligning everyone’s view and opinion, we just guide them directly.”

Introducing Points of Interest: Smarter 3D Collaboration and Orientation

We're introducing POIs so your mechanical & quality engineers can now mark additional information or features like screws, bolts or brackets. If you want to get creative, the same pattern can be applied in service, sales or manufacturing workflows - you choose the setting. POIs are customizable - choose the position, style, color and icon as you seem fit. POIs can be loaded on demand from any source or can be added dynamically in the 3DSpace. Use POI events like "hover" or "click" to build interactions. We’ve created an example as part of the release and are excited to see how you add POIs to your app!

Introducing USD Support

With the latest 3.12 release, instant3Dhub introduces support for Pixar’s Universal Scene Description (USD) format - making it possible to open and explore .usd, .usda, .usdc, and .usdz files right next to CAD or BIM data in one shared 3DSpace.

Until now, USD and CAD content often lived in different tools and environments. With instant3Dhub, you can now explore both formats side by side - interactively, collaboratively, and even in VR.

Now with CATIA Body Node support

With the 3.12 release of instant3Dhub, engineers and product teams can finally explore CATIA Body Leaf Nodes in full detail. Previously, you could only visualize parts at the top level. But now, with Body Node resolution, you can dive into individual solid bodies within a part, explore optional construction/invisible geometry and maintain CATIA metadata and model hierarchy with even higher fidelity.

This update unlocks true structural transparency for CATIA workflows in automotive, manufacturing and more with instant3Dhub.
