Did you find a solution? I'm interested in the same thing. Some 3rd party software to create a 3D model of an ellipsoid and then import it to Pro seems problematic. I think of problems lining up coordinate systems on the exported and imported object.

I'm trying to add or create an ellipsoid in an ArcGIS Pro local scene between two xyz points above ground. The distance between the two points is 8 miles. The ellipsoid radius is 50 feet. The points are 150 and 180 feet above ground, respectively. The points are described by latitude, longitude and height above ground. I've tried line-of-sight lines and buffered them in 3D. This gives a cylinder that is pretty good but the ellipsoid would be a better representation of reality. This picture below is the closest I've been able to get but it's far from usable. This will be used in 3D analysis so it needs to be spot on the locations. The attempt pictured started with a multipatch sphere. It is pitched 90 degrees on its side and stretched using the modify/scale tool. I need some way to move the object so that it can snap to the points. What might be ideal would be a GP tool or python script to create this ellipsoid from scratch. Given the two major axis z-value endpoints and the radius, create the object. The points represent radio antennas on towers and the ellipsoid represents the radio wave clearance zone or Fresnel zone. I've started looking at Blender and SketchUp but I don't know either package and would prefer a native ArcGIS solution. Any help will be appreciated. Thanks, Bill

Are to tools still available? When I click on the link to it gives me the following message.

Shwu-jing Jeng, Thank you for your quick response and letting me know about the new Mode and Status properties. I may use them in the future. It looks like adding a unique constraint on a field in the feature layer will work for our workflow. This provides a clean error result in the Outbox when the user tries to submit a survey with a duplicate value for the unique constraint field. Add a unique constraint to a field Thanks, Bill

My goal is to prevent duplicate survey records from getting entered into the hosted feature service. I would like for the survey submittal to act similar to a database form when you try to insert a record with a duplicate key, it throws an error and aborts. I would like the survey to check for a unique ID to see if it already exists in the feature service records. If it already exists then an error message is presented to the user telling them of the problem and the submittal is aborted. If no record exists with the key then the submittal goes through. Is this kind of behavior possible using Survey123 and the hosted feature service? In this post, I see how the surveys are moved to the Sent box when they are successfully submitted but that is not quite what we are looking for. Survey 123 Data in Sent folder not received in database Thanks, Bill

When trying to use the 3D Analyst Line of Sight tool with the scene default WorldElevation3D/Terrain3D as the parameter for Input Surface, I get the following error. ERROR 000732 Input Surface: Dataset https://elevation3d.arcgis.com/arcgis/rest/services/WorldElevation3D/Terrain3D/ImageServer does not exist or is not supported How can I use this dataset with the LOS tool? This is ArcGIS Pro 2.5 Thanks, Bill

I'm trying to extrude by a value in an attribute field for multipatch features. It seems the Extrusion options on the Appearance tab are disabled (greyed out). This is within a local Scene. It will let me extrude the multipatch features using the 3D handle (from there I can enter a height value) but I would like to use an attribute field instead. It will let me extrude a polygon feature class using an attribute field but not the multipatch feature class. This is not an imported scene. I'm in ArcGIS Pro 2.5. The multipatch layer has a horizontal and vertical spatial reference. I've been using this as a reference Define height characteristics for layers Thanks Bill

Ken, When you swapped out the layer and values returned, that surprised me. Then, when you asked about my map service setup, you got me looking harder at everything that I had glossed over before. My published map service looked alright. Nothing strange. So, looking harder at my code, I found my dumb mistake. I had set up my query wrong. the 'returnGeometry' setting was set to false. I changed it to true and got good results from the lines you provided. Thank you very much for taking the time to get me over this hurdle. Now I can have a good weekend and I hope you have one too. from this... IAH_Elev_FLayer .queryFeatures({ geometry: mapPoint, spatialRelationship: "intersects", returnGeometry: false, outFields: ["*"] }) to this... IAH_Elev_FLayer .queryFeatures({ geometry: mapPoint, spatialRelationship: "intersects", returnGeometry: true, outFields: ["*"] }) Thanks, Bill

Robert, yes the ObjectID and shape fields are not hidden. I can retrieve values for them. Ken, I will look more closely at how the service is set up. Hopefully something will look odd. Thank you.

Ken, Each of the featureLayers are polygons. Thanks, Bill
