I am working on my project in QGIS 2.18 through Graphical modeller and using some basic algorithms for polyline objects.
However, I do not understand why specification for Dissolve algorithm cannot be saved as a parameter in its window. Any ideas?
When I execute this model through Processing Toolbox it dramatically impacts my desired output. Looks like it simply does not remember my settings.
Example. I use
"SLINIE" field as a Dissolving parameter.
But after I click "OK" and open the window again I can not see that option.
Can you tell me please what I am missing?
