I am looking for a tool to use conceptual model to design my GIS project, so i am testing Enterprise Architect from sparxsystems with Arcgis 10.5.
So i download "house-smart-meter-example-geodatabase-model" example and i export it as Arcgis XML Worspace and i generated my Geodatabase, but when i export my new database witch is created from Enterprise Architect arcgis xml worksapce, i get a different diagram, and there is no relationship betwwen classes ? So what is the problem is it a compatiblity issues between Arcgis and Enterprise Architect.
