Syside Editor allows us to rapidly learn and understand SysML v2, to assess how we can use it to develop innovative aerospace systems in the future. The editing experience is already great, and I’m looking forward to what future versions will bring!

Syside meets me where I am, in the tools I'm already familiar with using. It has significantly lowered the friction I experience going from a blank page to quickly iterating between architecture and analysis. Syside is opening up new workflows for getting things done as a systems engineer.
