Hi everyone!!
I usually work with aeronautical maps adn for those charts at 1:1.000.000 or above, we often include the isogonic lines as a Geomagnetic reference for pilots.
To create Isogonic Lines I used a tool created and published by the ProductionMappingTeam (Make Isogonic Lines (ArcGIS 10.1) - Información general) but when I tried to execute it in ArcGIS Pro it did'nt work since the Magnetic Calculator tool is no longer available in ArcGIS Pro.
I've made some little adjustements in order to use the "Calculate Magnetic Component" ArcGIS Pro tool instead of the Magnetic Calculator, I've done around 25 different test to check its operation and it seems to work just fine. So I've attached my version of the tool (I didn't touch the documentation and geodatabase, I only modified the application) for you to check it and if works properly with woult be helpful to share it in a new post to all the ESRI Community.
Greetings,
Eduardo Ardila
