Description

This is a feature request for adding one extra tool to the editing toolbar. This tool would reverse the direction of lines. This is very handy for producing fancy symbology settings and also when using vector files created in Qgis as an input for profile generation modules in other GIS software such as GRASS and Saga.

Hello,

what do you think about having a Processing tool to do it (named like "Reverse lines") ? It would be stored into the QGIS Vector Geometry tools and we could use it to revert all the lines or polygons of a layer or just some part of the layer objects (with selection).

After digging with GRASS, you can use v.edit to flip the direction of selected vector lines. But v.edit is not in QGIS Processing so I think that a dedicated Processing tool that uses QGIS Python API could do the job...

+1. I think we should avoid adding new icons to the editing toolbar unless there's no other alternative, as that toolbar is already cluttered and confusing. A processing tool would be perfect for this.

Hello, bug triage...

fixed in d0625b8 for Processing.

There is also "a new expression" da436f9 named 'reverse' that does the same thing !

I am closing this feature request (and good job Nyall !).
