Omniverse DGN Converter [omni.kit.converter.dgn]#

Overview#

The Omniverse DGN Converter converts Bentley Microstation DGN files to OpenUSD format for use in NVIDIA’s Omniverse platform. Built on the Open Design Alliance (ODA) Drawings SDK, it ensures accurate conversion of 3D data to enable DGN models in USD-based workflows.

The extension serves as the user-facing component that configures and initiates conversions, while delegating the conversion work to the core converter running in a separate process to maintain stability.
