Yes. I sell a toolbox RivEX where all the tools are embedded into the toolbox. It works well and simplifies distribution. The only thing external is the help file, license file, shared modules and some sample data. I have come across an annoying quirk and I think it specific to VSCode. When you associate an IDE, in my case VSCode, with the arcpro it can open your code in VSCode and you have the full editing functionality of VSCode. This works about 95% of the time and when you close VSCode all your edits are transferred back into the embedded script. Nice! But... 5% of the time when you shut down VSCode it complete nukes your code and you loose everything! So imagine you are not working from a backup and all that new coding you've done is also lost! I've taught myself to select all the code and copy it, then close VSCode, then check the toolbox!

@HannesZiegler Great to see this in the help file, I think this will be really useful for developers, I know I'll start using it! Just a quick clarification, the help page for AddMessage() has been updated, does that mean the JSON structure does not work in AddError() and AddWarning() as neither of those pages appear to have be updated with this useful functionality? In my initial idea I was using AddError() as I am most likely to want people to jump out to an error code in an online manual.

OK what would be genuine examples of the two input parameters? oldzip = arcpy.GetParameterAsText(0) workspace_folder = arcpy.GetParameterAsText(1) Also setting parameter zero to be a File AND a Shapefile AND a Folder makes no sense to me, should it not simply be File with your filter set? Properties > Parameter 0: Data Type > File > Filter File (zip; shp) Properties > Parameter 0: Data Type > Shapefile Properties > Parameter 0: Data Type > Folder

OK when you run it does it print your "old zip files deleted message" but nothing happens?

Yes its not free. I'm also the author behind the tool. You now have that decision to make; spend hours of your time teaching yourself trace networks or linear referencing (which is a good thing and expands your knowledge of GIS), rely on free support from this community platform or just spend £100\£200 pounds depending if you are academic or not and have a suite of tools tailored to your needs requiring probably no more than an hour of reading the help file to get yourself up and running. If you think RivEX could help I recommend you download the demo version, have a play and get a sense of what its capable of doing.

You could use RivEX a tool for processing data specifically along river networks. The basic work flow in RivEX would be: prepare the river network> snap your point data to the network and deal with any un-snapped data> link sites. I provide many examples of workflows in the help file, your task matches this example. The link site tool not only tells you the distance but gives you a polyline to visualise the route and use in further spatial analysis.

Hi @RTPL_AU , Thank you for your innovative approach, certainly ticks the box of crafty! I feel there must be some symbol effect that would achieve what I'm looking for. The suppress effect sort of does it but relies on you individually setting vertices as control points (ain't going to happen!) and cut sounds exactly what I want but the help file is so poorly documented with no examples I can't get it to work the way I want. So either I'm messing it up or it can't do it, hence me reaching out to the user community. I hope others such as you offer further advice.

Hi Community, I want to try and utilise the cartographic effects that ArcPro 3.5 has to symbolise my data without having to alter the underlying geometry. To set the scene, here is my data. The purple cross section lines are compose of two vertices and they always intersect the black point on the blue line, but note there is no vertex at that location. I show one line selected in edit mode to prove this. I want to use one of the many cool symbol effects that ArcPro has to create a two colour line, say going from red to blue changing colour at that black point, something like below. Now one approach, because I know no better, is to actually split the line at the black point and colour up individually, but I don't want to do that, I want my line whole, composed of only two vertices intersecting the black point. Encoded into each line is the percentage along the line the black point is, its always from left to right. Having spent hours looking at the help file, which is poorly documented and I even tried the new AI assistant I have been unable to achieve the effect I desire. I've explored the cut effect and the suppress effect. The suppress effect requires control points but I don't want additional vertices in the lines. The cut effect seems to alter the appearance as one zooms in/out and its units (pt) I cannot seem to associate with the black points position even though I have turned on symbol property connection. I thought this would be a relatively simple symbology effect but I have failed completely to achieve it! May be I am barking up the wrong tree with my choice of symbol effect? Or this is an effect that is not supported? May be there is some other crafty way of doing this? Can anyone help? Tagging carto guru : @JohnNelsonEsri

I recently needed to share an image of a model in modelbuilder to an external client who does not have ESRI software. Through the model builder tab > Model > Export I created a PDF of the model. It all looked fine for me. So I attached it to an email and sent it to the client. For them the text looked like morse code so the PDF was useless. It appears that the export process does not embed fonts and there is no UI for adjusting options when exporting to PDF in model builder. I asked the ESRI document assistant AI and that confirms its a lack of embedded fonts but erroneously points you to the export tool under the share tab in ArcPro. So my idea is simply if you are not going to expose PDF options such as embedding fonts through that export button on the model builder tab then please embed fonts as a default so people can actually read the model! As it stands if your clients don't have those fonts (and not everyone has ESRI software) then sharing a PDF of the model is completely pointless as no one can read it.

What is this stand alone import tool? Can you provide a link to it?

‎11-06-2025

That wont make much sense if you are importing multiple shapefiles in one hit which are from different folders with different schemas. Why not just use the Export Features tool as you show as a way of importing into a geodatabase?

In ArcPro having navigated to the main Project options section, there is the info section where one can edit the metadata for the project, one such thing is the summary section. In the metadata editor section the summary allows up to 2048 characters as shown below If you type out a reasonably long summary (but less than the maximum character limit), when you go back to the Info section the text is truncated and one cannot read the full summary. The idea is to improve the UI of the info section to allow word wrapping so that users can actually read the summary!

This is a good idea, I too would like to be able to group maps into a "folder" under the Maps node in the Catalog Pane. As a use case scenario I am mapping the output of a tool called Tuflow. I have multiple rasters for different scenarios. It would help with organising the many maps I need to create which become map frames in a layout. Grouping them in some way would be very helpful.

@SantiagoGonzalez_Arriola , nice one! If you go to the help file for the tool at the bottom of every page is a "Feedback on this topic?" link. This appears the only way that we the end user can inform ESRI that the help page is incorrect or missing something useful. You should submit via that link your discovery on the incorrect keywords and point them to this thread.

Out of curiosity have you tried this approach with significantly larger datasets? For example hundreds of thousands of points and a polygon with thousands of holes? Or do you recommend this approach with smaller datasets?
