GGU-2D-SSFLOW: "Define nodes" menu item

You can use the left mouse button to define a new node or the right mouse button to delete a previously defined node. This menu item can also be reached using [F3]. Each new point created with this menu item will be assigned the default depths z values (see "z/Default depths" menu item.

When setting new nodes, the current x- and y-coordinates of the mouse are shown in the status bar at the bottom of the window. If, in the "Define additional nodes" group box, you define values for "y", another point is specified at the clicked x-position and the defined y-coordinate at each point you click with the mouse button. It is also useful to activate the grid in the next group box. You can thus define 6 points at the same time with a single mouse click with the settings shown.

If the system you are working on is available as a graphics file (for example a PDF or a bitmap file), you can display the graphic file on the screen using the Mini-CAD program module (see the "Mini-CAD" manual). This greatly simplifies input of the principal system nodes. Alternatively, you can also import a DXF file using Mini-CAD. This can contain the system outline, for example.

If Mini-CAD data are already present, the initial dialog box provides a check box with the option of locking on to Mini-CAD lines. If you activate this check box the mouse cursor appears as a rectangle with cross-hairs. If the end point of a Mini-CAD line is located within this rectangle the program will lock on to this point precisely; if a number of points are located within the rectangle, it will lock on to the one nearest the centre of the cross-hairs.
