Utilizing NVIDIA Omniverse to arrange 3D belongings from Constructing Data Fashions for AWS IoT TwinMaker

Introduction

The manufacturing and structure, engineering, building and operations (AECO) industries have extensively adopted constructing info mannequin (BIM) software program to generate correct 3D fashions to be used in a digital twin. These 3D fashions might be something from a manufacturing facility ground to a building website or workplace constructing. Nonetheless, exporting 3D fashions from BIM software program usually leads to inefficient fashions for rendering. The excessive rendering efficiency of a digital twin’s 3D scene is crucial for successfully monitoring operational occasions for the dual.

AWS IoT TwinMaker is a managed service for constructing digital twins to attach 3D fashions with real-world Web of Issues (IoT) knowledge. Utilizing this service, you’ll be able to create interactive dashboards for engineers on a plant ground to assist monitor and assessment their techniques’ reside and historic well being. These dashboards function a 3D scene to attach a digital duplicate of your constructing or machine to actual IoT knowledge. AWS IoT TwinMaker helps the Graphics Language Transmission Format (glTF) format for effectively rendering 3D scenes on a browser, nevertheless it at present doesn’t help any BIM codecs.

3D fashions created from a BIM file format like Autodesk Revit are troublesome to transform and optimize with out specialty software program. NVIDIA Omniverse is a modular growth platform for constructing and connecting OpenUSD-based 3D workflows and instruments, enabling the administration of BIM fashions, similar to Autodesk Revit, and getting ready the 3D mannequin to be used in a digital twin. Omniverse unlocks interoperability between 3D instruments and knowledge units and can be utilized to convert customary 3D and CAD file codecs like STP, OBJ and FBX to Common Scene Description (OpenUSD). Omniverse’s Autodesk Revit Connector plugin permits for live-sync growth on a BIM file. With NVIDIA know-how, it turns into doable to attach everybody, from engineers and constructing designers in Revit to builders, artists, and visualization specialists, in Omniverse for simultaneous collaboration and quicker iteration of mission workflows.

On this weblog, you’ll discover ways to create a 3D asset for a digital twin from an Autodesk Revit file utilizing the NVIDIA Omniverse platform and AWS IoT TwinMaker. The tutorial on this weblog converts the Autodesk Revit format to OpenUSD for processing in Omniverse. When happy together with your mannequin, you’ll export it to the glTF format and add it to AWS IoT TwinMaker.
