Some features in the multipoint feature class generate null values for the elevation fields (minimum, maximum, and average elevation) after running the Summarize Elevation tool.

Additional Information

Workaround

1. Convert the data from multipoint to single point using the Multipart To Singlepart tool.
2. Run the Summarize Elevation tool. It runs quickly (in less than a minute) to populate the value of all features.
