5. Read external data
A model can read values stored in another model — useful for shared assumptions or reference data.
- In the source model, note the cell entry name of the cell storage value you want to read.
- In the target model's Design mode, add a cell storage to the target cells and turn on Advanced mode.
- Set the value's Content source to EXTERNAL and point it at the source model and cell entry name, with Storage = READ.
- Reload and confirm the values appear.
- 1 Set Content source = EXTERNAL.
- 2 Choose the source and set Storage = READ.
note
Read a property that was actually stored at the source — reading a number fails if only text was saved.
