5. Read external data

A model can read values stored in another model — useful for shared assumptions or reference data.

1. In the source model, note the cell entry name of the cell storage value you want to read.
2. In the target model's Design mode, add a cell storage to the target cells and turn on Advanced mode.
3. Set the cell value type to Data borrowing, bind the owner model / cell storage, and set Data action = Read.
4. Reload and confirm the values appear.

• 1 Set Cell value type to Data borrowing (under Value storage).
• 2 Click Bind owner model and set Data action = Read.

note

Read a property that was actually stored at the source — reading a number fails if only text was saved.
