Object datum output a (Water Overlay)
| Icon | Key | Unit | Range | Description | Default value |
|---|---|---|---|---|---|
| OBJECT_DATUM_OUTPUT_A | m + datum | -10000 to 10000 | An array of values, one per timeframe. Each value indicates the water level at one side of the hydraulic structure, generally the entry. | None |
All hydraulic structures have an OBJECT_DATUM_OUTPUT_A attribute.
Notes
- This attribute does not need to be created when configuring the project. This attribute is created automatically by the Water Overlay when a calculation is performed. When the calculation is complete, the attribute is updated automatically.
- To avoid conflicts between multiple Water Overlays, each overlay appends its ID to this attribute name.
- This attribute is also visible when zoomed in on a hydraulic structure. The water levels on either side of the structure can be seen at each timeframe when a Water Overlay is selected.
