I think you need to do this with python. I asked ChatGPT:   import arcpy # Set the input feature class input_fc = r"path\to\your\feature\class" # Create an arcpy.da.UpdateCursor to iterate through each row in the feature class with arcpy.da.UpdateCursor(input_fc, ["SHAPE@"]) as cursor: for row in cursor: # Get the geometry of the current row line = row[0] # Create an empty array to hold the updated vertex coordinates new_vertices = arcpy.Array() # Iterate through each part of the line for part in line: # Create an empty array to hold the updated part vertices new_part = arcpy.Array() # Iterate through each vertex in the part for vertex in part: # Get the z-value of the current vertex in meters z_meters = vertex.Z # Convert the z-value to feet z_feet = z_meters * 3.28084 # Create a new Point object with the updated z-value in feet new_vertex = arcpy.Point(vertex.X, vertex.Y, z_feet) # Append the new vertex to the updated part new_part.append(new_vertex) # Append the updated part to the array of updated vertices new_vertices.append(new_part) # Create a new Polyline object with the updated vertex array # For the record, ChatGPT forgot to add the has_z argument below. It's not perfect! new_line = arcpy.Polyline(new_vertices, has_z=True) # Update the geometry of the current row with the new geometry row[0] = new_line # Update the cursor to save the changes to the current row cursor.updateRow(row)   I did a quick test and it worked for me. I ran it from a Notebook in my Pro project ... View more
