I am trying to use the Make Building Layer tool, using a revit model, with goal of uploading it to AGO and utilizing the building explorer tool. When I use the Make Building Layer tool, it fails and the only error I get is
"ERROR 999999: Something unexpected caused the tool to fail. Contact Esri Technical Support (http://esriurl.com/support) to Report a Bug, and refer to the error help for potential solutions or workarounds.
Failed to execute (MakeBuildingLayer)"
I have tried the tool with a few different data sets and none of them work. Any tips or advice would be great. Thanks!
