GGU-SETTLE: "Edit layer depths" menu item
This menu item allows editing of the base of a layer at the individual nodes of the triangle mesh. After clicking the menu item or activation using [F3] a message box opens. After double-clicking near the node to be edited you can change the depth of the layer base.

Using the "Modify" button, all existing depths can be increased or reduced by applying a constant. For example, if all depths are to be displaced by one metre, you only need to enter the constant once and all depth data for this profile will be adapted.
