Hi there!
I am working on a project, where I need to georeference CAD data for buildings with several floors! In earlier ArcGIS-versions it was possible to simply georeference the first floor, save the georeference as .wld and apply this georeference to the other floors via an "Import"-button. In the newer ArcGIS-versions, this button no longer exists.
In the solutions I found online it said, that you simply have to locate the .wld3 (not .wld anymore?) and .prj files in the homefolder of the CAD-data and the georeference will apply automatically to the rest of the data. However, once I do that and try to load the other floor plans to my map, it doesn't work (ArcGIS tries to load the data endlessly)!
I don't know if there is an easier way to do that or if I'm simply missing something out! I would be so glad about any kind of help!
