Yeah I think she did that to ensure that the input was indeed a connected network and not some load of unconnected nonsense! That tool could avoid that extension and build the graph as you have suggested. Anyway glad I had not somehow misunderstood your code sample. 😃

@HaydenWelch reviewing your code, if I have understood correctly it returns the ObjectID's of the features that intersect the input Polyline? I think @TeresaBartolomei is looking for a solution that would select all connected edges in a graph, as she specifically mentioned networks, so not just the immediate adjacent lines. If you wanted to program this you are basically looking at using the networkx module. I have also used this useful tool for coding up connected edges by an ID. This does not require network analyst as it is using networkx.

I would say that idea was not a duplicate but similar in concept. I'm thinking 1-band rasters with a unique value symbology, the sort you might have with a land cover raster. The other idea is talking about turning off/on bands. I'm talking about individual colours for a specific pixel value within the 1-band raster.

@ShaunWalbridge if as you say ESRI are not going to explore the idea of creating radio controls for geoprocessing tool (a bit of a shame) but can be "blagged" using the multivalue tool with some judicious validation code, why not provide a code sample in the help file to support developers? May be on that parameter page to show how radio controls can be simulated? Would help developers especially if they adopted a standard code style. If its good enough for ESRI it is good enough for us!

I think it was with ArcPro version 3.4 when a rather nifty capability was added to vector layer unique symbology; you can now tick on/off the display of the individual symbol by ticking on/off the checkbox. I highlight below. I find this functionality very useful when exploring data, dropping the visibility of specific features immediately, without the need of writing a definition query. My idea is that this functionality is to be made available for raster layers displaying unique values. This would be particularly useful when viewing land cover maps, I simply want to drop from display "Urban" or "Woodland" whilst exploring the results of some geoprocessing.

Can anyone from ESRI explain why the lock elements on the model builder view tab in 3.5.1 have been removed? One has to now create a new tab on the ribbon and add the buttons when they were perfectly ok where they were...

@Teri_Dane I think you have answered your own question. You now have to click the clear highlighted button in ArcPro.

You could just do a model to iterate over 10 loops doing a select by layer with the ADD to selection option... This approach assumes the features intersect in some way.

I too am experiencing this behaviour in 3.5.1 and believe its some sort of bug introduced by ESRI. I have the simplest of models as shown below. On each iteration the field map is lost/reset. The inputs have the same schema they are simply being exported with field lengths being adjusted. Its really frustrating and makes automation in modelbuilder impossible. I've tagged a few others who use modelbuilder and may have a solution? @ShitijMehta , @KoryKramer , @curtvprice

@DLowery thanks for clarifying the source of the error and your workaround is easy to implement. But... For a consistent user experience I think the tool needs to be able to deal with a layer from a map and I presume (not tested it) a layer object being passed around within a model is also susceptible to this error? If what I'm suggesting is impossible then at least update the help file for the Delete tool to say the tool has compatible issues with a layer and thus only able to interact with its feature class.

I think the best solution would be to move you to the field as in some datasets its quite useful to know what is before and after (I'm thinking census data). Hiding fields or moving to the front (e.g. next to OBJECTID) is likely to confuse things in. FYI if you are in Fields View check out the filter on the ribbon that filters down the rows, but that's no use if you are in table view mode....

This idea is essentially a cosmetic improvement. It would be useful if the Delete geoprocessing tool reported in its messaging how much space was recovered. I might select up multiple FeatureClasses in a file geodatabase and delete them. But how much have I recovered? Yes I know you can open the Catalog View and see the size, but I rarely access that view other than for metadata. As ESRI want us all to be using short-cut key strokes I quite often delete data using the CRTL+D approach as well as the geoprocessing tool. Would be good if both methods reported something as simple as "300MB deleted".

Hi Jamal, I downloaded your sample data and ran your model...it ran without error for me! Is the geodatabase you are writing into in a google drive/dropbox/one drive location, that may be file locking it? I've attached the file geodatabase with the output.

Which version of ArcPro are you using (by the way you should always mention such information)? The clip raster tool worked correctly for me resetting the extent to the clip. I'm using 3.4.3.

I think the source of the problem is the error 000539. Looking at your naming convention you are using, I'm going to guess that the input raster is INTEGER? If you need to retain it in integer, then rather than multiple by 0.5 try dividing by 2? Or convert the raster to a float.
