Adding 3D elements to 3D model 

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:

1. Snapshots: extract 3D elements from manually captured Snapshots. 

2. Related Scan Frames: add 3D elements from 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: Related Scan Frames are available for spaces scanned on or after 21 May 2024.

What are Related 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 Related 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 Related 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:

1. Open your scanned 3D model in the Metaroom Workspace.
2. 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.
3. Once selected, the Frame Interaction sidebar displays the image captured during scanning.
4. In the Frame Interaction sidebar, select a geometry mode: Box or Surface (see descriptions above).
5. Click on the element in the Snapshot to create a selection frame around it. The instance segmentation system will outline the detected object.
6. To refine the selection:
   • Hold SHIFT and click to add areas to the selection.
   • Hold ALT and click to remove areas from the selection.
7. 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.
8. Click Save 3D element to add the element to your 3D model.
9. Confirm the element’s position using the Transform Tool. Adjust the location if needed, then click ✔ in the Transform Tool toolbar to confirm.

How can I add 3D element from automatically captured Related Scan Frames? 

Follow these steps to add 3D elements from Related Scan Frames in the Metaroom Workspace:

1. Open your scanned 3D model in the Metaroom Workspace.
2. Click on any element in the 3D room model. The Frame Interaction sidebar will display the Related Scan Frames associated with that object.
3. Click on one of the Scan Frame to open it for editing.
4. In the Frame Interaction sidebar, select a geometry mode: Box or Surface (see descriptions above).
5. Click on the element in the Scan Frame to create a selection frame around it. The instance segmentation system will outline the detected object.
6. To refine the selection:
   • Hold SHIFT and click to add areas to the selection.
   • Hold ALT and click to remove areas from the selection.
7. 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.
8. Click Save 3D element to add the element to your 3D model.
9. Confirm the element’s position using the Transform Tool. Adjust the location if needed, then click ✔ in the Transform Tool toolbar to confirm.
