I'm running the thin indoor pathways tool - I've created preliminary pathways and transitions which look fine on the map - but the tool crashes and says its "unable to load the thinning template" and that certain network sources are missing in the output feature dataset (see screenshot). I'm not sure what these errors are referring to, but I have a feeling it may have something to do with me reprojecting the indoor model datasets to new coordinate systems. When adding the reprojected layers to the map it looks fine but when using those layers as inputs in other geoprocessing tools it indicates that the feature layer doesn't exist. The solution to this error could be unrelated, though. I've seen the two other related threads on this forum but the errors were different from mine. Hope y'all can help, thanks.
