boesiii / flowtrace Goto Github PK

I am trying to use this plugin to find connectivity issues in a linear network of pipes. I got to wondering how does the plugin determine down stream vs up stream? Does it go by the digitized direction? Or is it using the Z values in a Z aware feature class?

In the QGIS 3 version the first dialog now has a cancel button, which is an improvement (It seems to me like there is no reason for the first dialog to exist without a cancel button, unless you intend to make it display the selected layer name or number of selected features or something).
But if I click the cancel button there is a python error:

2019-10-04T17:01:10     WARNING    Traceback (most recent call last):

Flow Trace was working well but havent used it for a while and now no longer working....

An error has occured while executing Python code:

Hi,
just a short question: Do you have plans to update flowtrace to be compatible with QGIS3?

regards,
Thomas

the selection is not reaching all the upstream ends. could you please provide details about the used algorithm?

This could act as home page and code repo

Steps to reproduce

1. First
2. Second
3. Third
