Loss of connection in USD file and visualization query on Omniverse

[ FlexSim 24.2.2 ]

1) I am working on exporting a simulation model from FlexSim to NVIDIA Omniverse using the USD format. While the 3D assets and layout export successfully, the connections between objects—such as process flows, task links, and logical relationships—do not appear when I import the USD file into Omniverse. These connections are critical for accurately representing the simulation logic within Omniverse. Could you help me understand why these connections are not being preserved during the export process and suggest possible solutions to address this issue?

2) I am working on a simulation model where the front end is being developed on NVIDIA Omniverse to create an immersive and interactive 3D environment. However, the back end of the simulation, including the logic and KPI tracking, is handled in FlexSim, where I’ve created detailed dashboards to monitor key performance indicators. I want to ensure that these KPIs and dashboards are seamlessly integrated into the Omniverse platform so they can be tracked and visualized in real time within the 3D environment. How can I achieve this integration between FlexSim and Omniverse to display and update the dashboards effectively?

Samyak,

1) Nvidia Omniverse is a collaboration and visualization platform. It takes the 3D (and 2D) assets from the connected tools and does nothing but display them in a shared environment. Port connections, Process Flows and everything you mentioned that does not carry over from FlexSim into Omniverse are not visualization relevant. Omniverse does not know anything about those.

2) If you want results to be visible in Omniverse, you have to create them in FlexSim in a way that they have a 3D representation and therefore can be rendered in Omniverse.

1. Understood
2. How will we generate dashboards as a 3D asset on FlexSim?

There is no standard way to do so....you will have to collect the result information in tables or through a stats collector and then draw the graphs you desire in 3D space using FlexSim's draw commands in the "Drawing" category of the user manual or directly code in OpenGL.
