I had hoped to create a DTM raster using a series of point feature classes in a file geodatabase. Each feature class covers a grid with its points all lying 10m apart (all in a feature dataset with projected coordinate system). As there are almost 300 of them, I planned to use a ModelBuilder iteration to run through all the feature classes with… Show more
Thanks Curtis. I never thought the feature dataset might be the problem but it appears that it is, just as you thought. I've been using ArcMap 10.5.1 and tested things by copying a few of the feature classes to another geodatabase that doesn't have a feature dataset enclosing them. The model works fine then.
