I'd like to know how can I differentiate mixed input layer, in the graphical modeler of QGIS, based on the geometry type (line, point, polygon).
I used "multiple insert" -> "vector with no geometry required"; so I cannot use 3 "multiple insertions" for the 3 types of geometry, because it's not sure that there are layers with the 3 different types.
If there is a missing type, the dedicated insertion does not go ahead because it wants at least one layer of that type. So, I should try the way to put in input all layers of the map of every type, extract the layers of the same geometry type and go on with others algorithms...without the model stopping. Any suggestions?
