Adjust Slope + Elevation
💡 Both corrections — slope and elevation — in a single operation.
What it does
Adjust Drainage ▸ Adjust Slope + Elevation combines both adjustments into a single command: it first moves the network to the new elevation you enter and then recalculates the code-required slope — keeping both steps in the same undo group (a single Ctrl+Z reverts everything).
When to use it
When a design change affects both the outlet elevation and the slope of the drainage network — for example, after a structural or ground-level revision — and you want to solve both in one operation, without running Adjust Elevation and Adjust Slope separately.
Prerequisites
- Drainage network already modeled and connected.
- Knowing the new target elevation and which run/outlet will anchor the slope.
- Being in a plan or 3D view where the network is visible.

Common errors
| Symptom | Likely cause | Solution |
|---|---|---|
| Result identical to running only the elevation | The slope anchor was not set correctly | Run the command again reviewing the chosen anchor |
| The network does not recalculate entirely | The selected run is disconnected from the main network | Confirm connectivity before running the command |
