Network tracking

In each form, the user will find the command “Network tracking” in the upper left part. Tracing as well as routing can be carried out. In routing, a network-path search 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 tracking using the example of a point

The Network-tracking 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 tracking.
