(A depression will only be drained if it meets all of the minimum length, area, and volume criteria.)
‘**View Depressions**’ - All depressions will be made visible (including those that did not meet above requirements). ‘**Add Stop Line**’ - Creates a line on the screen with red anchors at each end. Drain lines will not cross this line. To confirm the placement, press the ‘**Lock Stop Lines**’ button. Pressing the white anchor in the centre of the lines will create another red anchor so that lines can be adjusted. Additional stop lines can be added by pressing the ‘**Add Stop Line**’ button again. ## **Edit Drains**  The ‘**Existing Drains**’ list will show all drains in the current project. - Tapping on any of the drains in the list will select or unselect it. Multiple drains can be selected at once. - ‘**Delete**’ will delete all of the selected drains. - ‘**Delete All**’ deletes all drains in the list (even if they have not been selected). - ‘**Move Lines**’ will allow all the drain lines on the surface to be edited(shown in bottom image). - Drain lines will have blue dots along them to indicate they can be moved to adjust the drain path. - Always start at the origin point (which can also be moved) and move downhill when moving drain lines. - The drain lines will automatically adjust their paths according to your changes to ensure they flow off the edge of the surface. - Press '**Save Changes**' to keep changes or ‘**Discard Changes**’ to revert to the original paths.NOTE: If you make an adjustment on a drain line and make a second adjustment closer to the origin point the first adjustment will revert to the line's original state. Auto-drains ALWAYS flow downhill from the point of the last change.
Once you are happy with the drains go back to the wizard page and use the ‘**Drain Design**’ function to set their profiles and cross sections. [Watch the Edit Drains video on YouTube](https://www.youtube.com/watch?v=2bidhKMix7s)
