Utilizing NVIDIA Omniverse to arrange 3D property 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 will be something from a manufacturing unit flooring to a building web site or workplace constructing. Nevertheless, exporting 3D fashions from BIM software program usually ends in 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 flooring to assist monitor and overview their methods’ dwell and historic well being. These dashboards function a 3D scene to attach a digital reproduction 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, however it at the moment doesn’t assist 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 improvement platform for constructing and connecting OpenUSD-based 3D workflows and instruments, enabling the administration of BIM fashions, similar to Autodesk Revit, and making 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 improvement on a BIM file. With NVIDIA expertise, it turns into potential to attach everybody, from engineers and constructing designers in Revit to builders, artists, and visualization consultants, in Omniverse for simultaneous collaboration and sooner iteration of mission workflows.

On this weblog, you’ll learn 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.
