Labeling each side of polygon with its length in ArcGIS Pro?
I am trying to figure out a way in ArcGIS Pro to label each side of a polygon with the length of the side without breaking it into individual polylines.
This is not possible as polygon parts between vertices do not have lengths. You will need to use lines.
I am not certain whether it is dimension functionality that you are after but according to the current ArcGIS Pro documentation:
Creating or editing dimensions is not currently supported in this release of ArcGIS Pro.
