I'm following the tutorial on Solar Analysis which can be found here: Introduction to solar analysis—3D Cities | ArcGIS for Desktop
Everything is working as expected right up tp the last step: Assign average solar radiation values.
After extracting the roofs and walls in the Esri CityEngine and exporting hem to a file geodatabase, I succesfully created a Radiation Raster using the SolarRadiationBurnBuildings tool found in the 3D City Solar Tools toolbox.
However, at the last step when attempting to use the SolarRaditationRoofZones tool I run into this: ERROR 999999: Error executing function. Failed to execute (Join Field (2)).
When I open up the model for the tool and go to Join Field (2), I can see that it attempts to use the field OBJECTID_1 as Output Join Field which doesn't exist. I change the field to OBJECTID, save changes and run the tool again and indeed this error is now gone. However a new error now appears: ERROR 999999: Error executing function. Failed to execute (Sample). Again I go into edit mode to see the model and go to Sample but there doesn't seem to be anything wrong with it. There are no errors nor is it trying to reference non-existing fields.
Unfortunately I am now completely stuck with only one step to go. I've looked on the internet for help but to no avail. I have followed every step in the tutorial carefully for about five times now but it always fails when using the SolarRaditationRoofZones tool.
Does anyone have any idea why this happens? Are there perhaps people who already succesfully completed the tutorial and can show me what i'm doing wrong? I am using all the data provided by the 3D Cities Template and Solar Analysis Sample Data and do exactly as told in the tutorial so I really wonder if it is at all possible to make it work with the given data.
I would really appreciate any help because I need to use the Solar Analysis tools for a project at work. I have recently bought an ArcGIS for Personal Use license and use ArcGIS for Desktop 10.4 and CityEngine 2016.0 on a Windows 8.1 64bit machine.
