Network Tracer

In each form, the user will find the command “Network Tracer” in the upper left part. Tracing as well as routing can be carried out. In routing, a NETwork path finding is carried out from a start point to an end point. A tracing searches for all connected elements. The direction of the search can be defined by the user. Likewise, intermediate points that the searched network path is to avoid or use can be defined.

Network Tracer using the example of a point

The Network Tracer command opens a selection for specifying the current object. The user can set the current element as a start, stop or end object for network tracer.


The Network Tracer form is opened after a selection has been made.

Explanation of the Network Tracer form


1. This displays the object selected for network tracing (with FID). The preceding symbol indicates whether the selected element was selected as a start, stop or end object.
2. Symbol for a start object. A new start object can be selected from the graphic by clicking on the button.
3. Symbol for a stop object. A new stop object can be selected from the graphic by clicking on the button.
4. Symbol for an end object. A new end object can be selected from the graphic by clicking on the button. This is possible only with the “Netzwegsuche”, but not with “Verbundene  suchen”.

If “Verbundene suchen” has been selected as the network tracer template, the network tracer can be started after selection of the start and possibly a stop object, as well as the direction of the network tracing.

The results are listed, can be highlighted in the graphic or opened in the form.


If “Netzwegsuche” has been selected as the network tracer template, an end object can be selected in addition to the start and stop objects.

If the stop conditions have been defined and confirmed with OK, they appear in the corresponding window.


13. This displays the defined stop conditions in the form.
