## AIR3D - 3D Observations

### Unmerge Merged Observation Item Boxes

[IMSFB-41953](https://cenosco.myjetbrains.com/youtrack/issue/IMSFB-41953)

It is now possible to unmerge merged Observation Item boxes. This can be helpful when Observation Items have been merged manually or automatically and you want to separate them into the original boxes.

### Attach multiple Observations to Existing ECHs

[IMSFB-42627](https://cenosco.myjetbrains.com/youtrack/issue/IMSFB-42627)

You can now add multiple Observation Items to an ECH from 3D Observation. Previously, Observation Items could only be added one at a time.

### Adding multiple Observation Items to an Area ECH

[IMSFB-43392](https://cenosco.myjetbrains.com/youtrack/issue/IMSFB-43392)

You can now add multiple Observation Items to an existing Area ECH by selecting an area in the 3D model.

When creating a CAIR Schedule, it will be possible to choose from the entire Area ECH or the by individual Equipment intersected by the Area if OB-Items have been added using the Area tool.

### New Statuses for 3D Observation Items

[IMSFB-42928](https://cenosco.myjetbrains.com/youtrack/issue/IMSFB-42928)

Two new statuses can now be assigned to Observation Items: **Below Threshold** and **Resolved**. Filters have also been updated to allow filtering based on those statuses.

### Paging of Observation Items

[IMSFB-44117](https://cenosco.myjetbrains.com/youtrack/issue/IMSFB-44117)

3D Observation now allows for paging of Observation Items, increasing responsiveness and reducing wait times for initial loading.

## AIR3D - 3D Localization

### Add 3D Position Manually to Annotation Items

[IMSFB-42628](https://cenosco.myjetbrains.com/youtrack/issue/IMSFB-42628)

For Annotation Items that do not have a calculated 3D position, it is now possible to assign a 3D location. Once the 3D location has been added to an annotation, it will be projected onto the 2D image.
