The Edit Window lies above the Graphics Window and below the Menu Bar. It includes a rows of edit fields and text strings. The edit fields are dim and the text strings blank if nothing is selected. When an entity such as a mesh node is selected, the controls display and allow editing of the coordinates and functional values associated with a selected object. This object could be a mesh node, grid node, scatter point, or corner of a grid frame. The coordinates are changed by typing in new values and hitting the ENTER or TAB key. If more than one entity is selected, only the z coordinate is available for editing. Entering a new value here will modify the bathymetry or depth of each of the selected entities. This allows the user to quickly model a feature such as a dredged channel or embankment.
