I have a layer with 4 roadclasses. For this layer I created a rule based symbolization, with 4 rules. In every rule I filter another roadclass and set a different symbolization and scale for this rule. Now I want to create a fifth rule "road direction", which should show the road direction as an arrow. But this arrow should be visible in different scale levels, depending on the roadclass.
For example: the roadclass 'A' the arrow should be visible from a scale 1:1500.000 the roadclass 'B' the arrow should be visible from a scale 1:400.000 and so on
Can I set this in one rule? The aim is, that I can activate or deactivate the rule "road direction" with one click. I don´t want to create 4 different rules and the arrow should not be added to the 4 rules for the roadclasses.
