Setting Burial Depth
Use the Burial section in the Inspector to set whether a pipe sits on the surface, is inset, or is buried — and at what depth.
Irrigation and drain pipes have burial settings that affect their modeled position. Drain pipes and channel drains can also carry a start-to-end depth change. Check the resulting elevation and slope against the terrain; a deeper end depth alone does not guarantee downstream fall on sloping ground.
Select the run
Select an irrigation pipe, drain pipe or supported channel. Expand Path properties in the Inspector, then the offered grouped fields. These are shared with the drawing tool’s parameter fields.
Choose placement
For a pipe, Burial offers On Surface, Buried and Inset. Buried exposes Depth and Dashed in 2D (when buried). Use the unit-aware Depth input; it accepts 0.1–1.5 m and displays the project’s metric or imperial units.
Set a depth change
For a supported drainage run, turn on Enable slope and enter Start Depth and End Depth. These describe depths relative to the run’s reference surface, not absolute elevations. Path order determines the start and end.
Read the result
The Inspector shows a computed Slope for a valid run with slope enabled. Check it rather than inferring fall only from depth values: terrain elevations also matter. A Reverse fall warning indicates a run that does not fall towards the intended outlet. Inspect the 3D path and use Undo to reverse an edit.
