Settle3D > Viewing and Display Options
The Depth control in the Sidebar allows you to interactively change the viewing depth for analysis results. This applies to:
data along a horizontal line (line query) in the Plan View
data at a point (point query) in the Plan View
graphs of line query data at a given depth
The depth can be changed in various ways:
in the Sidebar, click and drag on the vertical slider control which represents the depth of your soil profile
in the Sidebar, click on the spinner control to increase or decrease the depth, or enter a value with the keyboard
in the 3D View, you can directly click and drag on the horizontal contour plane to change the depth (hover the mouse at the edge of the horizontal contour plane until you see the two-way arrow cursor, then click and drag)
As you change the depth, the analysis results in all applicable views will be immediately updated.
Depth control in sidebar

Lock Depth
By default, the analysis results in all applicable views will be simultaneously
updated as you change the depth. If you wish to view data at different
depths in different views, then you can select the Lock
Depth
button under the Depth control in the Sidebar.
This allows you to independently change the depth in each view (first
click in the desired view).
