> **"There are no wheels yet, but the thing is running"**
|
|
|
|
## [TL;DR](https://en.wikipedia.org/wiki/TL%3BDR)
|
|
|
|
**This project explores [IFC5](https://github.com/buildingSMART/IFC5-development) and [Native IFC collaborative worklows](https://github.com/buildingSMART/IFC5-development/issues/2) based on Git.**
|
|
|
|
## Meet the Team
|
|
|
|
* **[Milovann Yanatchkov](https://rvba.fr/my_en.html)** : bug-hunter, aec-free-rider, associate-professor, kebab-case-lover.
|
|
* **Artem Igumnov** : civil-engineer, aec-ice-breaker
|
|
|
|
## The Challenge
|
|
|
|
* [AEC/O Hackathon 2025 Munich Edition](https://www.tum-venture-labs.de/events/aeco-hackathon-2025/)
|
|
* [Problem statement](https://github.com/vyzn-tech/ifc-data-bus?tab=readme-ov-file#problem-statement)
|
|
|
|
## Problem Statement
|
|
|
|
* Architects and planners rely on a **broad ecosystem of software tools**,
|
|
* yet **poor data integration between these tools creates major bottlenecks** in the design process.
|
|
* This fragmentation prevents holistic project optimization and slows down coordination.
|
|
|
|
### Data Stream
|
|
|
|
* Although **OpenBIM** ✅ aims to support **interoperability**, it still lacks robust mechanisms for
|
|
|
|
> **bi-directional data exchange** ✅
|
|
|
|
* —particularly when it comes to **re-integrating data into CAD and CDE environments**.
|
|
* **Existing initiatives often do not prioritize full OpenBIM compliance**, leaving a clear opportunity for alternative, standards-aligned solutions.
|
|
|
|
### 'Flat Modules' vs 'Monolithic Blob'
|
|
|
|
> At the same time, the emerging **modularized and layerized IFC5** standard ✅
|
|
|
|
* introduces new capabilities for more flexible, **fine-grained**, and machine-friendly data handling.
|
|
* These advances open the door to **new workflows** built around decentralized, **event-driven data exchange** rather than **monolithic file transfers**.

## The Experiment
|
|
|
|
### Embeding IFC5 Viewer within GitAec
|
|
|
|
* Sources can be find in the [ifcx branch](https://codeberg.org/rvba/forgejo/src/branch/ifcx) of GitAec
|
|
* The viewer is based on IFC5 BuildingSmart experiment [with some modifications](https://gitaec.org/rvba/ifc5)
|
|
|
|
**First experiments went a bit off the rail...**
|
|
|
|
|
|
|
|
**...but eventually, it ended fitting in**
|
|
|

|
## Generating IFC5
|
|
|
|
* [First test](http://localhost:3000/rvba/ifc-data-horse/commit/3c36ade1140461206173999a88f89a80b9fa72be) from [scratch](http://localhost:3000/rvba/ifc5/src/branch/main/viewer/src/utils/python/hack.py)
|
|
* [First Mesh](http://localhost:3000/rvba/ifc-data-horse/commit/12ed3ee4a136d6350775e4fb365a678d1e833ca5)
|
|
* [Obj exporter](http://localhost:3000/rvba/ifc-data-horse/commit/3399b8eef71ed9a4ba90422163e44b925e9f78c1)
|
|
* [Full example](http://localhost:3000/rvba/ifc-data-horse/src/branch/main/esempio_01%20edificius.ifcx)

Well .... [not really](http://localhost:3000/rvba/ifc-data-horse/commit/0dcf8710dd86cb4c4fcb6d01429b1099d5b507fa)
|

But wait,
|
|
|
|
|
|
|
|
|

|
|
And, ... yes [it works !](http://localhost:3000/rvba/ifc-data-horse/commit/f54640a77be062d5e66cd83beb1c063805a5db25) ...
