XYZ

Dear brothers 

Kindly, would like to ask  help for my question which is :

I have a polygon created in gis pro  then i convert this polygon into local scene (3D map)  thru "create Random points" i created points inside the polygon so when add xy  the coordinates are only X&Y  , but when i use insert  points   bu clicking inside the polygon   after that using "ADD XY "  the attributes contains  X Y Z

The Z value is due to the data existing in the 3D map for depth/height (elevation) purposes relative to the rest of the data in the scene. I'm going to guess when you added the "random point" with X/Y coordinates, Pro created the Z value on the fly and placed them based on the elevation settings in the map scene. 

Here are some resources that talk about the role of the Z value:

• Specify an elevation for z-aware features—ArcGIS Pro | Documentation
• Edit vertex z-values—ArcGIS Pro | Documentation
• Creating 3D Floor Plans in ArcGIS Pro and Scene Viewer - Resource Centre | Esri UK
