Anthony, You are not the only one affected by this behaviour. I too noticed if I make and break a single join created by the new Add Spatial Join tool introduced in ArcPro 3, you get that ever increasing table name join AddSpatialJoin_X where X is an ever increasing number. It makes using the tool in modelbuilder or a scripting environment impossible to use as you can't predict what the next increment is. I'm tagging @KoryKramer into this thread so he can rattle the cage and see what drops out! To the developers behind this tool: Is this really the intended behaviour? If so where is this information stored? Is it accessible so developers can build scripts to be able to construct valid expressions for field calculates? Unless I'm missing something, in an ideal world if I make then break the join I don't expect to see an ever increasing number, I think it should always be _AddSpatialJoin. This seems like a very powerful and useful tool but as it stands I can't use it as it breaks continuity in models, especially if they are exposed as model tools.

I have to admit I've never used M-enabled polygons so the "how" I assume is exactly the same as if you were using say an M-enabled polyline. Thus all the same methods you might call on an M-enabled polygon should be the same as the M-Polyline. The "why" would be anything to do with measuring along a border. May be you want to sample along a lake border at 200m intervals? Identify entrance points into some space? etc etc.

I agree with @DanPatterson , you need to explain how these points were created in the first place. A simple visual scan of your image and it is obvious there is NOT a 1-1 match. I highlight several examples in your image. How do you want to process these? DuncanHornby_1-1665997615973.png How were these points created, why have you allowed to have points unmatched? As Dan hints a near tool will erroneously identify points because some will be nearer to their adjacent rather than cross border. Finally how many lakes are to be processed, if it really is this one, by hand may be quicker rather than develop up a workflow to capture all cases?

You say "...this tool is run frequently...", but you don't say if you run the Append tool in a model or in a script? Either way it seems this is a limitation of the Append tool you are experiencing. You could explore emulating the Append tool with an arcpy InsertCursor(). If you are running your working flow as a model then such python code could be run in a Calculate Value tool so you can use the rest of the model logic.

My new laptop is not opening ArcMap 10.8.2 from home, just gets stuck at initializing license. Finally discovered this mad solution! I turned off wifi on my laptop, start Arcmap, it finally opens, then turn back on wifi... Nuts...but it works! 😃

I've always thought it was cumbersome to be forced to call the select layer by location tool when you wanted to do a spatial query. In ArcObjects you can feed in a QueryFilter or a SpatialFIlter into a search method which is a slicker approach. I think this idea would be an important improvement to arcpy. I often generate say a polygon and wish to know which geometries it is intersecting without the need for creating an selection across a layer. Such a cursor would close the gap between ArcObjects rich capabilities and arcpy. I can appreciate if ESRI are reticent to fiddling around with the existing cursor so to add another option to the table directly relevant to this idea I would be happy if ESRI made a new cursor that was just for spatial querying, so SearchCursor is for querying data by attributes and a "SpatialSearchCursor" would be the new cursor as suggested by @rkraujutis_hb.

Hannes, Thanks for the update and your solution to document this behaviour is welcomed. Duncan

I have a model in ArcMap which I use to demonstrate the power of models and automation in a presentation I sometimes give. I have migrated this model into ArcPro 3.0. Whilst the model runs without error and creates the correct output and selection I have noticed a difference in behaviour and I'm hoping one of the ESRI modelbuilder team can confirm this is actual behaviour or just some "glitch in the matrix"? Some of the outputs apply a layerfile so when the layer loads into the map its nicely displayed rather than taking on some default symbology. I show below how I assign this property DuncanHornby_0-1661427077496.png In ArcMap, the layer loads with the assigned symbology and is displayed immediately whilst the model is running. So as the model runs through to competition you see the layers build up in the map. Nice, just what I want and shows off modelbuilder! In ArcPro I see the layers get added to the TOC with the assigned symbology but the map does not refresh to display the layers until the model completes. In other words all the layers that are loaded into the map during model execution show all at once at the end of the model run, not as they are created and added to the map. Is this the way it is supposed to run and I have to just live with the difference? Duncan

To compliment this idea I have found you can't select a bunch of layers and tables in the TOC and remove them all from the map in one go. It has to be all just layers or all just tables.

I think this is the scenario where you need to convert your labeling into annotations and then you have full control over placement. I don't believe (I might be wrong) you can stop the label from moving along the line as you pan/zoom to different portions of the line.

I use model builder lots and it has been frustrating me for a long time that I can't press F2 to rename a model element. This is a great idea and a simple tweak to the UI that will bring much needed efficiency.

@KoryKramer I think this idea is very close to my idea and a candidate for merging, if you feel appropriate. I would like to expand on this by saying it would be good to archive experience builder sites along with their data. In my idea I envisage some button that packages up the entire folder of data, web maps, survey 123 forms and the experience builder site into a single package file which I can then download and archive locally allowing me to remove the data/site off AGOL. There should also be an equivalent upload of the package to allow the site to be unpacked and made available again.

I actually think this grouping behavior is not very good and unwanted behavior, there are several threads on this forum with lots of people (including me) demanding this behavior to be turned off! The good news is in ArcPro 3.0 you can now turn this off, its a new option in the Options section of ArcPro. Why I think it is bad is that it breaks downstream model logic as you don't know what the name is of your layer as it tags the layer name with a prefix. There is no mechanism to drill down to this name in arcpy so the output of a tool has a layer name that you have no control over or can access. I would personally recommend upgrading to 3.0 and turning this behavior off!
