Hi,
many many thanks for the answers. The differences between the Network Datasets and geometric networks are clear know. My intention was to find a backdoor in order to be able to simulate cascading effects in geometric networks. The point is, that i need the possibility to create Complex edges and Junctions as well as the possibility to link completely different networks to each other (multi-modal). That means for example a pump in a water network needs a power supply from power network. I am trying to find a solution for the linkage of these objects (logically) and the possibly use of the analyse tools.
Now it seems to me that my feeling about this stuff was right, that this whole stuff is not possible using the ESRI network (datasets and geometric) and that i have to create things on my own.
Regards
Thomas
