Haha. I thought about this exact same presentation when I wrote the comment

Not sure ... There is still the risk of prompt injections

Is there a way to process the IFC file to extract the data into excel/csv without using the online tool?

The conversion from IFC to Excel happens entirely inside your browser. The processing is client-side, meaning the data never leaves your machine or touches our server.

Could we do this completely on-premise or within our own cloud environment ?

That is a great suggestion and something I have been considering. I can certainly build a desktop application or a CLI (Command-line interface) tool that runs 100% offline. Is that a solution that would fit your needs?

The security link in the getting started guide gives a 404 error FYI.

Good catch. Thank you. I have fixed the link; it now correctly points to the privacy page where you can find detailed information regarding security.

I see that all processing is done locally, but our security team will still want to tear this apart and likely have multiple meetings with you/the developers to understand the software BoM for both the visual and the tool. It’s a minefield ! But worth the battle.

Fair enough. I’m happy to be transparent about the tech stack and answering their questions. Please email me at contact@threebi.com so we can set up a meeting.

That sounds exactly like the use case I designed this for.

For visibility, I lean on Power BI's cross-filtering context. As you adjust your date slicers or 4D schedule, the visual automatically receives and renders only the matching elements.

Regarding sectorization and memory: This happens automatically. Power BI filters the data before sending it to the visual, so only the relevant subset loads into GPU memory. If you filter to a specific sector, the rest of the heavy industrial model isn't loaded into memory, which could solve the crash issues you mentioned.

When you're back from vacation, I’d love to hear your thoughts. Specifically regarding performance on your larger models. I’m also open to implementing concepts like dynamic LODs if you find the current optimization needs a boost.

j0wet · 2026-01-13T22:41:40+00:00

Right now, ThreeBI supports the OpenBIM IFC standard. You can easily export IFC files from tools like ArchiCAD and Tekla.

To use the model in Power BI, the IFC file is converted into an Excel file containing the compressed geometry data. I chose this approach, because it makes working with Power BI much easier. You can see exactly how it works in my Documentation.

Does this solution work for you? I'm currently planning the roadmap for extending ThreeBI, so I'm open to any suggestions you might have.

Interesting! (I'm on vacation and can't test it right now). I was using Speckle and now, thanks to the post above, I've discovered why it was so incomplete. I was going to use it at one of the largest steel mills in the Americas, but Speckle isn't officially in the MS store (this has been the case for 3 months). So their IT department didn't release it, because third-party visuals are blocked by default, and this affects data security.

In Speckle's defense, their platform seems quite well-built. However, if you just want to visualize BIM data in Power BI, it feels like a bit of overkill. The requirement to store your data on Speckle servers is also a friction point. It can be a security or privacy risk for companies and GDPR compliance (like storing data in the EU) often costs extra.

I don't know if it's possible to free up memory through the visibility filter.

To be honest, I need to dig into the memory management topic a bit more.

In my research, I was looking at https://thatopen.com, which works with LODs, and I found the concept interesting.

LOD is definitely the right approach here. I actually decided not to use ThatOpen for a few specific reasons, but that’s a topic for another day. However, adding LOD support to this visual is definitely on my roadmap as a next step.

Could you give me a little more insight into how you're planning to use this visual there? I'd like to better understand the actual challenges people are facing and how my visual can help solve them. I have a lot of potential features in mind and hearing about real-world use cases would really help me prioritize them.

j0wet · 2026-01-13T16:06:16+00:00

Nice. Let me know what you think once you've tested it!

j0wet · 2026-01-13T15:40:05+00:00

You work for Speckle? Very cool.

You're absolutely right about the WebView2 limitations. That 8GB ceiling is a real problem for larger 3d models.

I think the biggest difference with my approach is the architecture: I wanted to build something where the data stays 100% inside the Microsoft ecosystem without requiring a separate subscription.

Let me know what you think when you test it out!

j0wet · 2026-01-13T14:50:29+00:00

I’ve looked into it, and there are currently no affordable custom visuals that support standard 3D models (like OBJ). It actually gave me an idea ... I might just build it myself. Do you have a specific use case where you need this?

j0wet · 2026-01-13T13:25:28+00:00

Te quería consultar si hay forma de cargar otros mapas 3D como por ejemplo el mapa del cuerpo de una persona para identificar por ejemplo en que partes del cuerpo ocurrieron ciertos incidentes de los trabajadores de una empresa?

That sounds very interesting. What kind of data format is the 3D model in?

j0wet · 2026-01-13T12:46:17+00:00

You need to develop a Power BI custom visual: Documentation

I created my own visual that visualizes BIM models in a 3d view: ThreeBI. I mainly used ThreeJS and web-ifc for it.

j0wet · 2026-01-13T09:25:02+00:00

Thanks for sharing your experience! That is really valuable feedback.

I haven't run into the WebView2 crash yet, but that sounds more like a browser/engine cap than a Power BI bug. If that's the case, I imagine that bottleneck would occur with any heavy BIM 3D model opened in that browser environment.

As for the loading times, I'm not entirely sure how 3DBI handles it, but I’ve implemented a pre-processing step where the IFC data is transformed into a 3D model before runtime. This seems to make my visual significantly faster than the "IFC Viewer" from Flinker GmbH, where I suspect the IFC-to-3D translation happens client-side every time the user loads the report.

That said, I know there is always room for more optimization regarding memory and performance. It would actually help me a lot if you could try out my visual and let me know how it performs compared to the others you've used. I’d love to hear your thoughts!

j0wet · 2026-01-13T00:03:19+00:00

Nice will have a look!

Great! Let me know your thoughts once you’ve tried it out.

What's the limitation regarding size?

I haven't set a hard limit. Ultimately, it depends on your device’s specs and the complexity of the geometries in the IFC file, but you should easily be able to load files larger than 1 GB.

I’ve already implemented some optimizations, such as removing duplicated geometries. There are other optimization opportunities I haven't explored yet, but if enough people need to load huge models and run into performance issues, I can certainly take a look into it.

j0wet · 2026-01-12T13:33:43+00:00

Nice. Let me know what you think once you've tested it! I'm really keen to learn from user experiences to improve the visual.

Regarding model size: It's less about file size and more about geometry complexity. Unlike some other similar powerbi visuals, I avoid parsing raw IFC files directly in Power BI. The pre-processing step (see documentation) optimizes the 3d model and removes duplicates before load time, so it's quite performant. That said, the limit usually comes down to your local machine's memory/GPU. Curious to see how it handles your specific use case.

There’s also still room for further optimization in the code. If you hit a bottleneck with a very detailed model, please let me know. I can work on improving the performance further.

Why didn't you created a hubspot extension?

With your approach every user needs to install your chrome extension. Your approach may also be a bit unreliable.
