Drain editing toolbar with Edit Drain, Merge Drains, Extend Drain and Split Drain buttons.

Edit Drain

Edit Drain button with a drain path and pencil.

Use this button to edit complete drain paths in the project.

Edit Drain window with a drain list, rename button, Select All, Delete and Close.

Press Edit drain to open a window listing the available drain paths. Select a drain, then press the corresponding button to rename or delete it.

Merge drains

Use this tool to join two drains at either end. Merging creates a copy of the original drains with a joining line. You then have the option to delete the originals.

Merge Drains button showing two drain paths joining.

Merge Drain panel with First drain and Second drain selectors and A/B merge points.

Extend drain

Extend Drain button showing a drain path and extension arrow.

Use this tool to extend a drain from either end of its surveyed path. This is useful when the drain needs to reach a location that the surveying vehicle could not access directly.

Press Extend Drain to open the extension screen. You can extend the drain in any direction.

The red arrow indicates both the direction of the extension and the end of the drain that will be extended.

Use the controls on the left to select a drain. Then choose the extension’s length, elevation and direction.

Extend Drain screen with drain and end selection, distance, relative and absolute elevation, direction and a red extension arrow.

Rel elevation adds or subtracts the entered value from the existing drain end’s elevation to calculate the extended end’s elevation.

Abs elevation sets the extended drain end’s elevation to the entered value.

For example, to extend a drain 1ft below an ending elevation of 100ft, use either of these values:

Rel elevation value: -1ft

Abs elevation value: 99ft

After making the adjustments, press Extend Drain.

Split drain

Use Split drain to divide one drain into two separate drains.

Split Drain button showing a divided drain path.

First, select the drain from the Which drain to split? drop-down menu at the bottom center.

Split drain screen with a profile and blue split arrow, Split at Distance controls, drain selector, New drain name and Split Drain At Point.

After selecting a drain, press anywhere along its profile. A blue arrow shows where the split will occur. You can also move the arrow using the left and right arrows to the right of Split at Distance.

Choose the Marker button to create a Marker for reference.

Enter a name in New drain name. When the settings are satisfactory, press Split Drain At Point to apply the split.

NOTE: The new drain name must differ from every existing drain name. If it matches an existing name, Split Drain At Point is disabled.
