Edit SysML v2 models with Eclipse SysON, an open-source and web-based MBSE modeling tool.
An implementation of the OMG’s specification SysML v2: language concepts, REST API, and textual interoperability format
SysON was presented during the Vendor Roadmaps and Implementation Status session of the MBSE Workshop held as part of the INCOSE International Workshop 2025, in Seville, Spain, on February 1, 2025.
We're thrilled to share that we've already made significant progress toward our goals!
As demonstrated in the quick demo, SysON is up and running—packed with powerful features and designed with a strong focus on user experience.
The project is on the right track and is already generating considerable interest.

SysML was created in 2005 as a standard for model-based systems engineering (MBSE) to elevate the role of models as primary tools for communication and documentation.
With system complexity continuing to escalate exponentially, and Digital Engineering emerging as a pivotal pillar to address an ever-challenging world, SysML 2.0 has been specified as the next-generation systems modeling language to improve precision, expressiveness, and usability.
SysON’s objective is to provide System Engineers with super easy access to this new standard, at minimal cost and great ease of use, with the guarantee of interoperability with other open-source MBSE tools notably Capella and Papyrus.
This will be achieved through three means: the support of the SysML 2.0 standard, the use of state-of-the-art web technologies, and an open-source approach.
SysON aims at facilitating systems engineers to seamlessly work with both SysML v2 and Capella. Exchange of architecture models with Capella will be natively supported in SysON.

But for years, players have struggled with a specific problem. The original Nukebound files were plagued with crashes, lag spikes, missing textures, and "failed to load" errors. This guide provides everything you need to know about the —a stable, playable version of this legendary hard demon level.

If you are using Megahack or the built-in 2.2 FPS bypass, lock your frame rate to a multiple of your monitor's refresh rate (e.g., 240 FPS or 360 FPS) to keep wave physics consistent. To help you get the best experience, let me know:

Geometry Dash Nukebound Fixed Download PC: How to Play the Corrected Level
The custom level "Nukebound" in Geometry Dash is famous for its intense wave gameplay and apocalyptic visual design. Players searching for a "fixed" download version for PC are typically looking to resolve performance lag, broken triggers from game updates, or screen tearing.
This was the moment of the Great Crash. In the original version, the screen would freeze here, the audio looping into a digital scream. Elias held his breath, his eyes wide. The original Nukebound files were plagued with crashes,
Download only level files or verified mods:
Always be cautious when downloading custom levels. Avoid ".exe" files claiming to be the level. Nukebound is a game level file (usually with a .gmd or decompressed folder structure), not a standalone game.
Since Nukebound is played within the main game, ensure you have Geometry Dash installed on your Windows PC: Official Method (Steam): Purchase and download the game from the Steam Store . This is the most stable version for PC. Alternative (Google Play Games): You can use the Google Play Games Beta
Obeo provides expertise to help you integrate SysON within your organization, and tailor or extend it to fit your needs.

Obeo is also preparing a secure cloud-based offering to provide SysON as a fully hosted SaaS solution, enabling users to access and use it without any deployment on their machines or servers.
Stay tuned…
Alongside the open source development of SysON, Obeo is working on advanced commercial features to support cutting-edge deployments for large-scale and/or mission-critical projects.
Stay tuned…The project team works in an iterative mode to deliver a new version every 8 weeks.
The first release of SysON, version 2023.12, was launched in December 2023 by Obeo and CEA List.
The SysON roadmap takes into account user feedback and needs identified as part of an Open Innovation approach.
For the next months, our main goals include:
In 2025, we will intensify our collaborations with industrial partners to elevate SysON to the forefront of SysML V2 modeling tool excellence
and prepare it for professional, operational, and large-scale deployment.
