Hello dear all,

I created testing data for Trace network. I had lot of issue in my data but after cleaning, I think data are OK. These are simple data of River basin our river Bečva.

But although I solved issues in topology, I am still not able to make nice Downstream Trace. Tool always select only one feature. I feel lost, probably this is issue somewhere in my data. Can someone help me?

Downstream

I attached my project and I would really appreciate it if someone could help me.

Many thanks and stay save,
David.

Hello everyone,
issue was solved. Trace Network works well. Our data weren't ideal, we need fix it by topology rule Must Not Have Dangles, Cluster Tolerance was 0,5m. This fixed small conectivity issues in our data.
