NullAttributeMapper, AttributeCreator or otherWhat do people use to set default values for attributes?In the case that I have is a json document - in the case values are missing I need to set a default value. Ideally I’d use an NullAttributeMapper, however, there are upwards of 10 values I need to set and I don’t want to use 10 of these. The other option I see is an AttributeCreator/Manager with conditional values which is what I would normally do.  

Hi,I recently moved to FME Form 2025.0.3 from FME Workbench 2021.1.2.The install is on a central windows machine. Some workbenches run as other users. ArcMap and ArcPro (3.4) are also installed on this machine.All our workbenches involve ESRI enterprise geodatabase readers or writers, so require an ESRI licence to run.Users of FME all have named user licences for ArcPro, they are able to launch Pro and obtain a licence on the central machine.When I use FME Form there is no issue accessing the ESRI licence and using the readers/writer. However when testing with other users, who have the same type of named user ESRI licence, FME reports the error: “Worker 6428 > Unable to perform any licensing related tasks. Please check your Esri ArcGIS Compatibility workspace parameter, found in Navigator -> Workspace Parameters -> Translation. This 64-bit version of FME requires ArcGIS Desktop along with 64-bit Background Geoprocessing; ArcGIS Pro; or ArcGIS Enterprise. Refer to this this art

New to FME, have a client using FME and want to read and traverse through a MicroStation DGN file on a number of client machines. What’s the best way to achieve this?Does a license allow me to distribute a DLL for use on their clients?Is there a batch interface I can use?Steve @ Hexagon 

Hello,FME workbench has a strong tendency to take longer and longer to perform editing tasks (NOT translation) the bigger the workspace gets.Disclaimer: My workspace contains over 2100 transformers and I am aware that editing transformer links upstream will cause FME to recalculate downstream. However, my frustration is due to the fact that even minor modifications to very small independent workflows in the workspace seem to trigger the same recalculation as the workbench becomes unresponsive for 5-15 seconds every time I do something. This even happens when i move a transformer without altering any workspace logic. It even happens when I move an unconnected transformer! Extremely debilitating to productivity.Is this a known issue / any optimization planned?Using FME Workbench on Windows x64 2016.1. Confirmed on multiple PCs.

Referring to this (closed) post: https://community.safe.com/ideas/httpcaller-to-specify-client-certificates-31782​@LizAtSafe mentioned that the feature is released. I can find it nowhere in the documentation. Could someone point me to the right direction on how to authenticate at an API,using a certificate?

Hi I am using the schema scanner to extract the schema of data in both the original and revised datasets by comparing with a change detector.  This is working fine and i can get everything into a single table from the insert output, however i want to be able to show delete and updated as separate tables within the email.Any ideas of the best way to do this?  

I’m taking the opportunity to plug an idea I posted a while ago: I really want the ability to embed linked custom transformers via the command line / automatically. I have a bunch of projects which are just custom transformers - these custom transformers are often part of projects which I deliver to customers. It’s much easier for me to deliver a single workspace with the transformer embedded in the workplace rather than have them deal with linked custom transformers.But in my development I want to be able to reference/use the latest version of the transformer, this is especially true it the transformer is used in a tonne of different workspaces. I have an automated build process which will package up the workspace(s) along with documentation. But what I’m unable to do is to embed these transformers into the workspace - if I want to do that then I need to do it manually and it’s a pain. 

I have a workspace and I want to turn it into a CutsomTransformer - as part of that process I want to rename a bunch of attributes to include a prefix (e.g., from a JSONFlattener) - This is mostly for readability.For example I have several attributes which are coming from a JSONFlattner - in the original I never added a prefix, however, now I want to prefix with something like “layer.” - so something like “extent” would become “layer.extent”. The issues is that when I add that prefix in then all the downstream transformers which use the properties break. Obviously going through and changing them would have taken me less time than writing this question but it’s certainly not the first time I’ve had this kind of issue.In similar situations in the past I’ve been lazy and have simply renamed the new attribute to the old value. There are quite a few situations where I think having this kind of functionality would do a lot to improve workspaces readability with little effort on the authors p

I’ve been a big of a hater of the Parameter Editor window for a while - I’ve always had it disabled in favor for more canvas space, plus I just like bigger windows to work with in general.Today though, while working in the PythonCaller, I really wanted to look at my log file - I always had to keep closing the editor to scroll though the log. Then I remembered about the Parameter Editor window and it made things waaay easier. I’m not sure I’ll keep it like this but for now I’m really liking it. 

Hello everyone,I am having difficulty adding data to an existing DGN file.I have a CSV containing X, Y, Z and a Matricule.I want to add this data into a DGN that already contains points and predefined layers (levels).I just want to complete the DGN with my CSV data, putting the new elements into the correct layers.I find DGN handling in FME much harder compared to working with simple shapefile layers.I have managed to roughly merge my points, but the values do not go into the correct layers and they don’t take the original DGN styling.For example, I want the Z value from my CSV to go into the layer “CALC_PTTOPO_ALT”On paper I thought this would be simple, but I can’t find the solution.Can you help me, or tell me if there is an easier way?In the long run, I would just like to update my DGN regularly when I have new points.Thanks in advance,

This is a quick rough guide on how to print your workspace as a PDF. This should be a standard feature of FME, but it is not. Printing off a workbench is very useful when creating documentation about workbenches. I am surprised at the lengths I had to go to for this. Step 1:Follow this, or any other guide, on how to set up CUSTOM Paper Size for PDFs I recommend adding size: *Option: CUSTOMSIZE{*rcNameID: =USER_DEFINED_SIZE_DISPLAY*MinSize: PAIR(936000, 1332000)*MaxSize: PAIR(109728000, 164592000)*MaxPrintableWidth: 109728000}Then, printing the item requires another bit of jankyness to make this work:  click landscape make sure there is only 1 page press fit to scree now it looks “ok” to print, but it isnt yet. hit the print button (mine is missing for some reason) select print to pdf hit preferences hit advanced  choose your newly defined page size hit apply DO NOT PRINT YET. exit the window.Finally, hit the fit to page once again (step 3)Now, hit print again, and print your item to p

I have a json file that holds coordinates in the following format: How an I extract these coordinates to make the polygon that they form? I have tried reading the data through a text reader instead of a JSON reader and I have tried the JSONFragementor/JSONExtractor transformers but I can’t get the json query right, everything gets rejected.Any ideas?​​​​​​​

Does anyone know how to delete an FME Flow connection in FME Form 2025+?FME Flow connections used to be configured in the FME Options dialog under the Web Connections tab but they are no longer there in FME 2025. Instead, they are now available from the main FME Form toolbar.Using the toolbar I can create a new connection, select and edit an existing connection, but I don’t see any option to delete an existing connection. Even the FME Form documentation does not provide any help.

I have a field Filename where the naming convention is usually 2025 May Report.xlsx or 2025 January Report.xlsx I have used the filenamepart extractor transformer to fetch the filename along with a string searcher transformer just to extract the year and month  from the filename. Now I want to create an additional field where I can flip the year and month -→ Month Year. How can i build the regex to achieve this? Also I might be expecting different scenarios where January is written as Jan, JAN or january

I want to Create a choice User Parameter that will show column list details from database, This will enable me to select my choice column field that when I run the workflow, I will be able to get the output result for only the column in a fanout dataset.

I wonder if there’s a way for me to hack the web connection during run time to expose the AGOL Organization URL and token so I can use this URL downstream.The ArcGISOnline Connector returns these as format attributes but I have the extra overhead of running the right action item to expose them. Submitted an Idea related to this:  

We currently have an .asp script that builds a url/uri based on a selected prefix and document ID.When the OK button is clicked, the url/uri is opened in a new browser tab.The server where the asp script is located is being retired so we need to come up with an alternative.The parameters are Plan Type and Plan Number.The parameters are used to generate a path to the document to open. Eg. \\sample.file.path\resources\SCIMsPlans\pm12345.pdfI have converted the ASP to Python and made a self contained executable that works well but staff are used to accessing the plan search via a web link. I thought a FME web app may be suitable for this.Can anyone point me to the correct transformers to use for this or even better, a sample workspace.In case it helps, below is a snippet from the python script that builds the file path and opens the document.        # The Plan document ID number        name = self.plan_input.text().strip()                # If 'dp' is selected, use 'DP_DepositedPlans' to b

Hi,I get the following error when attempting to publish a workbench from FME form to FME Flow:User is not authorized.The specified user credentials were not authorized to perform this action.

I have an export of an MS Whiteboard in pdf form. (I also have the JSON and HTML. The JSON doesn’t store the note contents).  PDF reader is spotting text, but I’m struggling to pull it out ‘per note’. Any ideas? 

I have a workspace that reads an excel spreadsheet that contains 20,000+ rows with file names and paths to DWG files which works 99.9% of the time.  The simplified process is as follows:Filter the list of files from the spreadsheet to remove certain filename patterns Read the dwg model space, but only keep lines that are on layers that starts with BND Test to see that they fit in a polygon using spatialfilter clean up attributers and write the results to shp fileFor some reason when it hits a certain file, the process stops when it hits an error (even it is set to continue on rejected feature and ignore failed readers is set to Yes.  I have attached a zip with the log file as well as a FFS file it create which contains a single line that doesn't appear to be anything unusual or unexpected.  My work-around for now is to skip the offending file by using the “features to read” settings on the reader.  Given that there are 20,000+ files, I tend to run 5000 at a time.

I want to change paths for readers in multiple FME workbench files and Ive been trying all day without success to do so without doing it manually. Does anyone know how to do this :) ?For example from \\192.168.221.35\ftp\hofn\Höfn-skolplagnir.shp to \\192.168.221.50\ftp\hofn\Höfn-skolplagnir.shpwith the only change being the ip path from ending at 35 to ending with 50 but for multible at once :)I already tried changing in Notepad as suggested here with all the paths but it doesnt work for some reason. Also consulted chatgpt for Powershell scripts of different variety...Thank you for reading :)

Hi All,I have a folder of csv files with the naming convention like this : Insp1.csv, Obsv1.csv, Insp2.csv, Obsv2.csv etc etc.I have written a workbench to read in Insp1.csv and Obsv1.csv and derive the outputs i want. These csv files are pairs and both are needed to create the output. I have a folder of many InspX.csv and ObsvX.csv files that I want to process. I have set up a Directory and File Pathnames reader than I think I want to pass into a workspace runner that calls the workbench to process the files with parameters.  How to I get FME to iterate over my files and each time the runner is called iterate to the next pair of csv’s? ie first time is run use Insp1.csv and Obsv1.csv, the second time use Insp2.csv and Obsv2.cvs etc etcMany Thanks Goatboy

I was having a bit of a poke around with how Workbench calls the AI APIs and noticed that the method of sending the workspace was to first convert it to graphviz format. I had initially thought the fmw would’ve been passed and parsed instead,Converting to graphviz is a pretty cool step and could be used when producing reports or documentation on workspaces. I know people have asked for similar functionalities in the past re exporting the workspace as a graphic: Is that conversion something that the end user can tap into? I’m going to shamelessly tag ​@rylanatsafe ​@mark2atsafe and ​@NickAtSafe here, as while they might not be the people directly responsible for answering such a question, I feel like they might be able to point this question in the right direction!

I would like to use the AI assist feature in a programmatic way.  Is this possible?Currently it is available only as a GUI inside FME workbenchI would like to provide a prompt + workspace file, call an API, and then get a response based on the workspace context
