Georeferenced Enhanced Sync Profile Setup A Geo-referenced Enhanced Sync uses a shared coordinate reference system between the IFC model and the IVION site to streamline alignment without three manually placed alignment pairs. ### 1. Activate Enhanced Sync On the sync type prompt, click **Yes, Activate Enhanced Sync.** ![Prompt to activate Enhanced Sync for 3D models in NavVis application.](https://cdn.document360.io/bf174766-fa1a-4fe1-a4d7-b1db1e7cb996/Images/Documentation/Forma Connector Guide Slide 22 - Image 1.png?sv=2026-02-06&spr=https&st=2026-11-01T14%3A57%3A39Z&se=2026-11-01T15%3A57%3A39Z&sr=c&sp=r&sig=wVPm7%2B3YC5EDhwFI21iifNhDIIeVMo5IhgYbjwn23yM%3D) ### 2. Select your georeferenced IFC model Select the georeferenced .ifc model within your Forma project to sync to your IVION site.

Confirm shared reference system You will see a Coordinate System Check prompt asking whether your IFC model and IVION site are configured in the same Shared Reference System (SRS) and use meters as the unit. - If yes, click **Yes** to proceed. - If unsure, see Step 7 - Georeferencing Requirements for IFC Models. ![Instructions for aligning 3D models with the digital twin in Autodesk software.](https://cdn.document360.io/bf174766-fa1a-4fe1-a4d7-b1db1e7cb996/Images/Documentation/Forma Connector Guide Slide 22 - Image 3.png?sv=2026-02-06&spr=https&st=2026-11-01T14%3A57%3A39Z&se=2026-11-01T15%3A57%3A39Z&sr=c&sp=r&sig=wVPm7%2B3YC5EDhwFI21iifNhDIIeVMo5IhgYbjwn23yM%3D) > [!NOTE] > **Note:** Project units must be set to meters for this option to work. ### 4. Create a calibration issue in Autodesk Forma The georeferenced workflow requires a single calibration issue in Autodesk Forma, used for calculation purposes related to the model viewer. It can be placed anywhere and deleted after setup. 1. Click **Open 3D Model**, place one issue of the category Design Coordination anywhere in the model. Return to the connector and click **Proceed.** ![Viewer calibration instructions for Autodesk Forma Data Management model with action buttons.](https://cdn.document360.io/bf174766-fa1a-4fe1-a4d7-b1db1e7cb996/Images/Documentation/image-1780058633055.png?sv=2026-02-06&spr=https&st=2026-11-01T14%3A57%3A39Z&se=2026-11-01T15%3A57%3A39Z&sr=c&sp=r&sig=wVPm7%2B3YC5EDhwFI21iifNhDIIeVMo5IhgYbjwn23yM%3D) ### 5.

Georeferencing Requirements for IFC Models Before configuring a Georeferenced Enhanced Sync, ensure your IFC model meets the following requirements. ### Project Units In your authoring tool (e.g., Autodesk Revit), set the project units for Length to meters. ![Revit project settings showing units for length, area, and other parameters.](https://cdn.document360.io/bf174766-fa1a-4fe1-a4d7-b1db1e7cb996/Images/Documentation/Forma Connector Guide Slide 26 - Image 1.png?sv=2026-02-06&spr=https&st=2026-11-01T14%3A57%3A39Z&se=2026-11-01T15%3A57%3A39Z&sr=c&sp=r&sig=wVPm7%2B3YC5EDhwFI21iifNhDIIeVMo5IhgYbjwn23yM%3D) ### Export Settings For georeferenced IFC models, confirm the following before export: - Project units are set to meters. - The export uses the IFC4 schema. - The model uses the same EPSG code as specified in IVION. The EPSG code defines the projected coordinate reference system and must match between your authoring environment and your IVION site for georeferencing to work correctly. ![Editing site location with EPSG code and geographic reference details in software interface.](https://cdn.document360.io/bf174766-fa1a-4fe1-a4d7-b1db1e7cb996/Images/Documentation/Forma Connector Guide Slide 27 - Image 1.png?sv=2026-02-06&spr=https&st=2026-11-01T14%3A57%3A39Z&se=2026-11-01T15%3A57%3A39Z&sr=c&sp=r&sig=wVPm7%2B3YC5EDhwFI21iifNhDIIeVMo5IhgYbjwn23yM%3D) ## 8. Verifying your Site and Model are Correctly Georeferenced After configuring the Georeferenced Enhanced Sync, verify that the IVION site and the IFC model resolve to the same real-world coordinates. ### 1. Enable coordinate display in IVION 1. In IVION, open the measurement tool. Go to **Settings** and enable Cursor coordinates. Ensure that the correct Spatial reference system is selected. ![A 3D view of a mechanical space with measurement tools and settings options displayed.](https://cdn.document360.io/bf174766-fa1a-4fe1-a4d7-b1db1e7cb996/Images/Documentation/Forma Connector Guide Slide 29 - Image 2.png?sv=2026-02-06&spr=https&st=2026-11-01T14%3A57%3A39Z&se=2026-11-01T15%3A57%3A39Z&sr=c&sp=r&sig=wVPm7%2B3YC5EDhwFI21iifNhDIIeVMo5IhgYbjwn23yM%3D) 1. You can now hover over points in the IVION viewer to see their coordinates. ![A view of industrial stairs and equipment with measurement tools displayed on the side.](https://cdn.document360.io/bf174766-fa1a-4fe1-a4d7-b1db1e7cb996/Images/Documentation/Forma Connector Guide Slide 29 - Image 3.png?sv=2026-02-06&spr=https&st=2026-11-01T14%3A57%3A39Z&se=2026-11-01T15%3A57%3A39Z&sr=c&sp=r&sig=wVPm7%2B3YC5EDhwFI21iifNhDIIeVMo5IhgYbjwn23yM%3D) ### 2. Check coordinates in Autodesk Forma 1. Open the georeferenced IFC model in Autodesk Forma Data Management. Use the measurement tools to create a spot coordinate and set the Unit Type to meters. ![3D model of a water treatment facility with highlighted stairs and equipment locations.](https://cdn.document360.io/bf174766-fa1a-4fe1-a4d7-b1db1e7cb996/Images/Documentation/Forma Connector Guide Slide 30 - Image 2.png?sv=2026-02-06&spr=https&st=2026-11-01T14%3A57%3A39Z&se=2026-11-01T15%3A57%3A39Z&sr=c&sp=r&sig=wVPm7%2B3YC5EDhwFI21iifNhDIIeVMo5IhgYbjwn23yM%3D) ### 3. Compare coordinates 1. Spot-check matching points across both systems. If the coordinate values in IVION and Autodesk Forma are within a few centimeters of each other, your IVION site and IFC model are correctly configured. ![3D model of a staircase with measurement tools and coordinates displayed on the side.](https://cdn.document360.io/bf174766-fa1a-4fe1-a4d7-b1db1e7cb996/Images/Documentation/Forma Connector Guide Slide 30 - Image 3.png?sv=2026-02-06&spr=https&st=2026-11-01T14%3A57%3A39Z&se=2026-11-01T15%3A57%3A39Z&sr=c&sp=r&sig=wVPm7%2B3YC5EDhwFI21iifNhDIIeVMo5IhgYbjwn23yM%3D) 1. For larger sites or models, verify several points spread across the site to confirm consistent accuracy.
