In the Arcpro 3.3 release they added to geometry objects scale and move, so lets hope they add rotate to a geometries list of methods. ... View more

Dave, This is great news but I feel cautious to use it as you say its "not officially supported", which to me could indicate that it could be removed without warning as well as becoming official. Now this is just me but I find using json horrible, it's just all brackets within brackets with colons upon colons to me! I have always found json hard to decypher. So if the Pro team were to consider to make this a supported feature (which would be great!) then I ask them to consider an easier approach like a <a></a> or maybe some sort of object based approach?  For example a geoprocessing tool returns a result object which one can tap into the various properties. May be the AddMessage can take of a sort of message object? Just an idea. Anyway this I think would be really useful and surprised that it's not in the documentation, so at the minimum you could suggest to the team to expand the help documentation to show off this very useful property. Thanks! Duncan ... View more

Dear @ChrisUnderwood, Attached is a zip file with an access database, points have been deliberately moved but the same issue still persists. I create an OLE link to it using the 16.0 OLE DB Provider Add table to map Create an EVENT THEME (I don't want XY Table to Point before you suggest it), spatial reference is set to British_National_Grid. Try and select a single point selects everything and we don't see the selection in the layers attribute table. It will be interesting to hear if you get the same issues and if there is a solution? By the way I using ArcPro 3.3.   Duncan ... View more

Hi @ChrisUnderwood , just checking if I can share a sample of the database, if I can't I will try to spoof up something. Either way will get back to you as this is a real show stopper for us and stopping a major project in our team from migrating away from ArcMap, where it just works flawlessly. ... View more

What @MervynLotter suggest is a good solution but I just want to add that you could have also used the Create Random Points tool and set the constraining feature class to the buffers. ... View more

It's not clear what you are asking from your sketch. So are you saying that the black dot is a location of one point? Where the other location is a stack of 3 points, but rather than being displayed as a stack of points that would obscure each other you want them dispersed in a linear fashion as you have shown? If what I ask is correct then what's the maximum number of samples at a location, 3 as you show or 3,000? Whilst display order of stacked data can be fiddled around with in ArcPro, be aware that AGOL is incapable of showing custom display orders. you need to edit you question add more precise detail in what it is you actually want. ...

I have a point layer in field maps which has a numeric field called ID. In AGOL, when viewing the layer in map viewer I had open up its form and for the ID field created a calculate expression: return count($layer) + 1;   This will set the ID to the number of features plus 1. That's how I auto populate the ID field with unique ID numbers. ... View more

I would not use that tool, that's for creating a spatial reference which you would then assign to a dataset. If the tessellation tool is complaining about a lack of a coordinate system it would strongly suggest to me that your input dataset does not have a coordinate system. You don't say what the input layer is, how it was created and although you claim to say it is projected you never state what it is!  If you go to the properties  of the layer (from contents panel) and look under sources what does the spatial reference say? If it says unknown then the dataset is missing specific information and that's something that can happen with shapefiles (which by the way are a very old data format, use file geodatabase). If you know for a fact that it should be in coordinates "XYZ" then you can use the Define Projection tool to set it to "XYZ". This tool is simply adding the information it is not actually doing a projection of the data. ... View more

You don't say anything about how your data is stored and where? Is your data local, network or a service being throttled over the internet? Is your data a file geodatabase or shapefiles or some transfer format like geojson? If a shapefile you need to add a spatial index, but best performance is always a local file geodatabase. ...

OK try creating the field but not calling it length as that is a database reserved word, try something like len_m, see if that works? ... View more
