Function introduction

Build an architectural scene

The architectural scene is a digital twin environment used for managing and viewing Building Information Models (BIM), performing facility operations and maintenance, and overseeing frontline operations. By creating an architectural scene, you can more effectively organize and manage the building model and its related data, thereby enhancing the overall efficiency of building operations and management.

The process of building the architectural scene is shown in the diagram below:

You can view the built architectural scene through the DataMesh Inspector for facility management, engineering inspections, and other operational tasks.

Create an architectural scene

The specific steps for creating an architectural scene are as follows:

1. Access the BIM Data page

On the DataMesh FactVerse platform, navigate to Digital Assets> BIM Data in the function module navigation bar to access the BIM Data page.

2. New architectural scene
a) In the BIM Data page, click New to open the New window.
b) Fill in the architectural scene information in the New window and click the Confirm button when completed.

In the New window, you need to provide the following information about the architectural scene:

• • Name (Required): The name of the architectural scene.
  • Directory (Required): The storage directory for the architectural scene. After creating the scene, the system will create a hidden folder named after the architectural scene in this directory to store the constructed files and digital twins of the equipment. For example, after successfully creating the architectural scene “DM Office,” a hidden folder named “DM Office” will be automatically created in its directory.
  • Description: You can add a brief text description to introduce or describe the architectural scene.
  • Cover: You can choose a standard format image from your local files as the scene’s cover. Selecting an appropriate cover image can enhance the recognizability of the architectural scene.

Process BIM file

Processing BIM files is intended to convert Revit files into a format usable by DataMesh Inspector. The processed files can be used to build architectural scenes.

During the BIM file processing, you have two options: online processing and local processing.

Online Processing (FactVerse File Conversion Service):

• • Convenience: No need to install or configure any local software. The FactVerse platform automatically handles the file conversion. You simply need to upload the Revit file to convert it into a usable format.
  • License required: Online processing requires a license for the FactVerse platform’s file conversion service.
  • Applicable scenarios: Suitable for users who need to quickly convert BIM files into usable file formats, especially those who do not wish to perform complex operations locally or lack the necessary tools.

Local Processing (Using AutoDesk Revit and 3ds Max with Plugins):

• • Control: Users have complete control over the file conversion process, making it suitable for those who require highly customized settings.
  • Version Compatibility: Local processing supports higher versions of Revit files (Revit 2023 to Revit 2025), ideal for users handling files from these versions.
  • Revit and 3ds Max Required: Local processing requires the installation and configuration of Revit and 3ds Max software on the device.
  • Applicable Scenarios: Suitable for users with specific needs, such as local deployment environments or those requiring processing of large and complex files. Through local processing, users can ensure the accuracy and compliance of the generated files.

Online processing

Upload .rvt files from Revit 2021 to Revit 2023 versions to the DataMesh FactVerse platform, and use FactVerse’s file conversion service for processing, after which you can proceed to build architectural scenes.

The specific steps are as follows:

1. Access the Resources page

On the DataMesh FactVerse platform, select Digital Assets in the functional module navigation bar, then click on Resources to enter the Resources page.

2. Upload .rvt Files

On the Resources page, click the Upload button to upload an RVT file from your local device.

You can also import engineering cloud resources (drawings, documents, models) to the FactVerse platform with one click via the Autodesk Engineering Cloud platform. Note: The company administrators need to set up the Autodesk BIM360 account in the Enterprise Management module for users within the enterprise tenant to use this import function.
