I don't know if it's even planned, but you could expect that reshaping of a polygon follows the rules of "snapping and digitizing options". In advanced settings, i've chosen "avoid intersection". It works for new created polygons, but not for reshaping.


#1 Updated by Giovanni Manghi 4 months ago

  • Regression? changed from No to Yes
  • Priority changed from Normal to High

This works as expected on 2.18 so it's a regression.

  • Status changed from Open to Feedback

I can't reproduce. I've tested with 2.18 and 3.0 and the behavior is the same.

Note that reshaping with "avoid intersections" does NOT avoid intersections within the same layer, and it did not in 2.18 either.

Is this still an issue with current nightlies?
