## Microsoft OneDrive

Connect OneDrive to access and manage files directly in Dalus.

### Connect OneDrive

1. Open the **Teams** page, select a team, then go to the **Integrations** tab
2. Select **Microsoft OneDrive** and click **Connect**
3. Sign in with Microsoft and approve access

### Import from OneDrive

1. Open the **Documents Hub**
2. Click **Import** and select **OneDrive**
3. Choose files and folders to import

## Onshape

Connect Onshape to sync variables and part mass properties with your Dalus models.

### Connect Onshape

1. Open the **Teams** page, select a team, then go to the **Integrations** tab
2. Select **Onshape** and click **Connect**
3. Paste your Onshape API key and secret, then save

### Link Onshape Parts

Link a Part Studio part to sync mass properties (mass, volume, surface area, and related values).

1. Open a model and select a part
2. In the right sidebar, choose **Link to Onshape**

3. Select the Onshape document, workspace/version/microversion, and Part Studio
4. Choose the part (or the aggregate part) and confirm

### Notes

* Variable bindings are bidirectional; the most recent write wins
* Part links sync mass properties into Dalus variables
* Onshape connections are team-scoped; admins and owners manage access

## Data Synchronization

### Importing from Other MBSE Tools

Dalus can import models from other systems-engineering platforms. Supported formats include:

* **SysML XMI** — Standard interchange format for SysML models
* **ReqIF** — Requirements Interchange Format for requirements data
* **Custom JSON** — Contact support for custom mapping configurations

### Exporting to Other Platforms

Export Dalus models for use in downstream tools:

| Target        | Format        | Use Case                 |
| ------------- | ------------- | ------------------------ |
| Spreadsheets  | Excel (.xlsx) | Offline editing, sharing |
| Documentation | PDF, Word     | Formal deliverables      |
| Other MBSE    | SysML         | Tool interoperability    |
