All local authorities are required to produce plans showing property ownership and T-Marks to identify the ownership of boundaries. Previously these tools were available in Productivity Suite and they are now available using ArcGIS Pro. (Although not as intuitive).
At Nottingham City, we are looking to provide an on-line web app to provide this functionality, however the functionality does not export across to either Portal or AGOL. There is no option to rotate either text or a point (T-marks can be created from a point feature class).

As all local authorities have a a legal requirement to produce these plans, an on-line tool would help facilitate the production of plans without requiring the use of ArcGIS Pro for this one function.
