hi, You might want to check your data then.  I just created a demo dataset in a fgdb and it worked for me. Bearing in mind this is a very simple dataset with single part polylines. start point: var line = Geometry($feature); var path = line.paths[0]; var pt = path[0]; return pt.z end point: var line = Geometry($feature); var path = line.paths[0]; var pt = path[-1]; return pt.z I created three lines and calculated their geometries in fields using the gp tool, then the same using arcade.  I then added globalids and attribute rules for two new fields.  Finally I digitised two new lines connecting the start and ends of the previously created ones.  You can see the attributes were updated successfully and they match the pre-existing lines. I wanted to insert an image but apparently I don't have permission now.

Hi there, I think this may help. It looks through a list of depths and exports a feature class from the source data that is queried for each depth, and then also a tin. It's just a quick hack so there's no error handling etc. Also I'm not sure how to properly embed code, hopefully this works.
