How to create 3D Buildings with photogrammetry (DSM and DTM)

Question

Hello community! I am having sleepless nights because the solution "3D Buildings" of ESRI do not work for my case and I don't know why. In the ESRI example it's an area of Pleasanton where through building footprints , the DSM and the DTM it is possible to create LOD2 buildings. I have an area in Sarajevo where i would like to do the same. First i substracted the DTM from the DSM to get the nDSM. After that I had to segment the building footprints. That didn't work first but I divided the feature class into three parts and with that it worked. Now I want to create the 3D buildings with the task that i downloaded from ESRI solutions. But i always get an error and I don't know why. Can someone help me?

Hellu, my previous answer somehow disappeared. It's strange that the task works with the example area of Pleasanton though. If it's a problem of the Version of ArcGIS Pro, it should also not run there. I opened a support case. If I will get more information about how to solve it, I will let you know. (-:

I am Also having an issue with the 3D buildings solution. The tool called "Create Footprints from Raster" (which I was running on a raster created in an earlier step called "Void Fill") is failing. I have tried splitting my rasters into smaller parts etc.  I am not sure what is going on, since this workflow worked perfectly when I ran it back in June on ArcPro Version 3.2.  I have since upgraded to ArcPro 3.3.  I have tested this tool on the original data that I used successfully back in June, and I still get an error. Please Help!
