You need to show your new code, stating the error message without context is not that much use. Also when you share code use the insert code button (via the 3 dots), a screen shot is no use as the first thing people want to do is copy your code and attempt to replicate the issue, you can't do that with a screenshot! ...

RivEX, a geoprocessing toolbox for vector river networks can generate the metrics you require. It has several tools for measuring sites along river networks. If you just want the distance value then use the Find sites upstream of a site tool. If you want to visualise the line that links the two sites then use the Link Sites tool. Have a look at the worked examples to inspire your use of RivEX. ... View more

May be your if statements are failing because the number of rooms is a NUMBER? You are querying if it is a TEXT, e.g. $feature.L <> "0"  should be $feature.L != 0 ... View more

Well fake some data that creates the same problem and share? If it turns out that your fake data does not recreate the problem it would suggest an issue with your data/data source. Also its good practise to state which version of Arcpro you are using. ... View more

You need to edit your question and include a screen shot of how you set up the intersect tool itself, i.e what are the parameter settings? As it stands it is difficult to answer your question. ... View more

You can add text, images and even hyperlinks to a script summary. With these set you or your user need only move the cursor over the blue ? in the circle to display it. ... View more

I don't think radio controls exist currently in the geoprocessing tool interface. There is this page that may be of interest to you where in a few cases you can choose an alternate interface for certain parameter types. ... View more

At this point all I can suggest is you share a sample of data that causes the problem for others to try and replicate and offer up a potential solution. ... View more

Have you actually read the help file? It tells you exactly what would happen if you set the Output Coordinate system? Usage notes are quite clear if the Output Coordinate system is different to the input then the output is projected. ... View more

Did you run the DEM through fill sinks BEFORE generating the flow direction? Also what is your I:\ drive? Try writing to C:\ ... View more

Unless I have misunderstood this idea, I think it is already offered, although the quick look suggestion would make the Tools help page more "readable". Take the Generate Definition Query From Selection (Data Management) tool introduced in 3.4. Go to its help page and click on Other Versions and its clear that its not available in 3.3 or earlier.   ... View more

1] To expose the sub model in your master model, edit the sub model and expose the output of the collect values tool as a PARAMETER. Just right click on it and select parameter. Save you changes then drag 'n' drop the sub-model into the master model and you will be able to feed the list of rasters into the next tool. 2] You don't say where the year value is stored? I assume its part of the file path name of the rasters that the iterator is stepping over? If so use the calculate value tool to extract that part of the file name and then use inline variable substitution to help build your output raster name. I would so this all in the sub-model. ...

Modelbuilder does produce a log, it's the message window, the latest version of ArcPro 3.4 even expands this with additional messaging, you just need to turn it on. I suggest you explore the options settings... A new tool with the 3.4 now even allows you to display custom messages as a model runs. Although to my knowledge modelbuilder does not allow you to log to a text file you can simply press the copy button on the message window and paste it into notepad! Have you tried that? Finally creating emails as alerts could be done by developing some python and having it run that in a calculate value tool.  So basically most of what you ask is already there, you just need to dive into the options and get to know modelbuilder better. ...
