ArcGIS Pro: symbol marker placement offset in map units

[JohannesLindner]

When symbolising line features, there is an effect to place markers at measured map units. This effect also supplies the option to have the markers offset from the line, but only in points.

I would like to place markers with an offset measured in map units (e.g. meters), so that it doesn't depend on the map scale.

Thank you for submitting this idea Johannes Lindner‌

This can be changed from the default of pt in the Unit options—ArcGIS Pro | Documentation 

Units and symbol size—ArcGIS Pro | Documentation 

Does that work for you?
