With AI-assisted instance segmentation, you can add unudentified 3D elements to your 3D room model directly from Scan Frames in the Metaroom Workspace. There are two ways to do this:
- Snapshots: extract 3D elements from manually captured Snapshots.
- Scan Frames: add 3D elements from related Scan Frames automatically captured during the scan.
When adding a 3D element, you can choose one of two geometry modes:
- Box: use this mode when it’s important to display the 3D dimensions of the element — for example, when adding a column to a room.
- Surface: use this mode for flat or complex-geometry elements — for example, when adding a luminaire to the ceiling.
Please note: Scan Frames are available for spaces scanned on or after 21 May 2024.
What are Scan Frames?
While you digitize a space with the Metaroom Scan App, the app automatically captures frames and links them to the corresponding elements in the 3D model. These are called Scan Frames.
When you open a 3D scene in the Metaroom Workspace and click on any element within the model, the Frame Interaction sidebar displays the Scan Frames associated with that element. Each frame shows a different perspective of the same area, giving you a complete visual reference — useful for reviewing the space, adding missing elements, and helping team members who have not visited the site get a clear understanding of it.
How do I add 3D elements from manually captured Snapshots?
Follow these steps to add 3D elements from a Snapshot in the Metaroom Workspace:
- Open your scanned 3D model in the Metaroom Workspace.
- Find the Snapshot you want to work with:
- In the Model Tree, filter by type: click the Type dropdown and select Snapshot, or
- Click directly on the Snapshot icon in the 3D model view — this automatically selects the corresponding item in the Model Tree.
- Once selected, the Frame Interaction sidebar displays the image captured during scanning.
- In the Frame Interaction sidebar, select a geometry mode: Box or Surface (see descriptions above).
- Click on the element in the Snapshot to create a selection frame around it. The instance segmentation system will outline the detected object.
- To refine the selection:
- Hold SHIFT and click to add areas to the selection.
- Hold ALT and click to remove areas from the selection.
- Optionally, add metadata to the 3D element:
- Element Name: enter a name to be displayed in the Model Tree.
- IFC Type: type the IFC element name or click the dropdown to select from the available IFC types.
- Tags: add a color tag for faster navigation.
- Click Save 3D element to add the element to your 3D model.
- Confirm the element’s position using the Transform Tool. Adjust the location if needed, then click ✔ in the Transform Tool toolbar to confirm.
