FME Form

Hello Forum, I have point dataset with 5600 points at an address level. Each point has a ‘score’ value of between 1 and 100. I need to create a hexagon grid. And then assign to each hexagon the score value of the point, or the average score values of the points, that fall into each hexagon. If only one point record falls into a hexagon, say with a score of 42, then that hexagon will inherit a score of 42. But if several points fall into a hexagon, say with scores of 13, 56 and 22, then assign the average value of 30.3 to the hexagon they fall into.  I also need to define the size of the hexagons/hexagon grid. I’ve been looking

All I want to do is create a TIN from a point CSV. I have used the TINGenerator transformer, but the TIN that is created does not have any elevation. The geometry is 3D in the Inspector, but it does not show any height information. If I create a TIN in ArcGIS, it has the correct elevation. I will also post my workflow. Can anyone help me?  

Hi All,Has anyone experienced issues with the AutodeskDocsConnector transformer when downloading Revit files from Autodesk Construction Cloud (ACC)?In my case, when the Revit files are downloaded via the transformer as part of an automation, the resulting files are noticeably larger in size and FME is unable to recognise them as valid Revit files, returning an error. However, when I download the same Revit files manually from ACC, the file size is smaller and the files are read correctly in FME without any issues.I would appreciate any insights or similar experiences, as well as suggestions on what might be causing this discrepancy.I’m using FME(R) 2024.2.4.0 (20250318 - Build 24831 - WIN64)Thanks :)

Hallo everyone,I copied and upgraded an ArcGIS Dimension Feature Class (File GDB) using ArcPy.However, when trying to read it in FME 2024 (FeatureReader / File Geodatabase Reader), I get this error:Unable to convert row to 'DimensionFeature'FME can see the schema, but fails when reading the features.Does FME support reading Dimension Feature Classes, or is there a known workaround?Thanks.

We’re currently in the process of looking to move to a newer version of FME Form (2025.2) but we’ve hit an issue where we can’t meet the required dependencies for adding a Smallworld reader regardless of having the correct files in the right locations. If we open an older workspace with the reader already added, it will still complain about missing dependencies but the workspace will execute correctly.If you select ‘Update Reader’ from the navigator you can add additional feature types etc and change parameters, but you can’t add a new reader due to the missing dependencies. I noted that there was a Fix in Build 25811, but when I tested in 2025.1 (before the fix), there are no issues adding a Smallworld reader. I understand that the Smallworld user group probably isn’t the largest but is anyone

I have a COG with a scale factor (excerpt from GDALInfo)Band 1 Block=1024x1024 Type=Int32, ColorInterp=Gray  Min=-50313.000 Max=57304.000  Minimum=-50313.000, Maximum=57304.000, Mean=4745.177, StdDev=7550.452  NoData Value=-32767  Offset: 0,   Scale:0.1How do I apply this scale factor in FME?   If I clip the input and create a new tif,  the scale factor is dropped and the values are 10 times the expected.In this particular case I can just scale the value back down, but in general, is there a way to retrieve the scale factor and apply it? 

Hi I am using the OpenAIChatGPTConnecter in FME Form and entered all relevant details but receiving this error- Could not resolve hostname Obviously something network related, any further ideas? I cannot ping to the endpoint from command prompt.

I’m trying to follow the FME Form course from a MAC and one of the very first exercises is using a Esri Geodatabase (File Geodb Open API) writer. Unfortunately I’m getting this error on the platform. Is there any workaround for this?

Hello All Please any idea / guess how i could maintain the intensity in output and decimate E57 point cloud file. Below is my current workflow. This is my first time working with E57 filetype.  

Hi FME Community,I'm currently working on a BIM/GIS integration project where I need to regularly update Revit files into a 3D GIS platform. The initial setup is already in place: I've created the 3D environment and published some Revit files to Portal for ArcGIS using ArcGIS Pro.Here’s the current workflow:Load the Revit file into ArcGIS Pro within a 3D scene. Share the scene to Portal. This results in three published items: a scene-hosted layer, a feature-hosted layer, and a web scene.Since the engineering team updates the Revit files weekly, I’m exploring ways to automate this process using FME Form and Flow. So far, I’ve considered two options:Option 1:Use PythonCaller to replace the Revit file in ArcGIS Pro and re-share the web scene to Portal. This would overwrite the existing scene-hosted layer, feature-hosted layer, and web scene. N

I have an HTTP caller using a GET Request, to access an API site using a Web Connection for authentication. I am trying to find a way for it to return (either within the JSON response body or otherwise) the access token which is generated when the process runsI have Accept and Content Type as my headers. I have tried: Storing the cookies doing grant_type = client_credentials in the Query String Parameters.  Creating a list for the Headers (no token content within that)In the setting for my web connection, I have this:But I am not returning anything called ‘access_token’ in the response body. To be clear, my process works as intended, but due to new constraints we need to store the access token that is generated every time to store it to use downs

I have a workbench that takes data from Oracle, merges it with a few other tables, runs it through a schema scanner and then tries to output to a file geodatabase.The file geodatabase has the merged table created but it only contains the schema definition not the data. The output from the schema scanner shows the points in the graphics display. These are the transformers that scan and output Here is the Feature Writer  The summary is showing the feature count  

I am not sure why I am struggling with this one… I have tried quite a few options.  What I would like to do is:Pull Alignment file from an XML (this has the starting value as an attribute, end value can be calculated by start value + line length) Set Start and End Measures Kick out an m-enabled polyline that is geometrically calibratedI have the workbench set up to pull this in, using a geometry coercer to make sure it is a line, then I have been trying the measure generator and measure setters to get these values to stick with no luck.    

HiI am encountering a critical issue when using the ArcGIS Online Feature Service Writer (within a FeatureWriter transformer) in a dynamic workspace.When a specific column contains data that AGOL deems "invalid HTML" (e.g., strings containing <, >, or specific URL parameters), the translation fails with a Fatal Error. Instead of rejecting only the problematic feature or failing just that specific layer, the entire FME Engine stops, preventing the rest of the workspace from processing other layers. I have a custom Transformer that read, process and write individual layer. this custom transformer has a group by set to unique layer id.Current Configuration:Writer: ESRI Feature Service Writer (Dynamic).Transformer: FeatureWriterError Message: ArcGIS Online Feature Service Writer: 'column_name' has invalid HTML content.What I Need Help With:Error Handling: How can I configure the FeatureWriter or the

I would like to use gdalinfo to read the metadata/header for a folder of rasterfiles to get the extent and of each file. Ggalinfo can read this without loading the raster itself. This greatly speeds up the process.Can we use the gdal implementation of FME to do this and if so how? The goal is to also have this working on FME Flow.Example of gdalinfo output:gdalinfo "C:\path\to\file\1.img"Driver: HFA/Erdas Imagine Images (.img)Files: C:\path\to\file\1.imgSize is 200, 130Origin = (209000.000000000000000,529000.000000000000000)Pixel Size = (100.000000000000000,-100.000000000000000)Metadata:  DataType=GenericCorner Coordinates:Upper Left  (  209000.000,  529000.000)Lower Left  (  209000.000,  516000.000)Upper Right (  229000.000,  529000.000)Lower Right (  229000.000,  516000.000)Center      (  219000.000,  522500.000)Band 1 Block=64x64 Type=Float32, ColorInterp=Undefined  Des

 Hi,I am using the Matcher transformer to find pairs of features with the same attribute value.Now I want to create a new attribute rel_obj that stores the ObjectID of the other feature in the matched pair as in the image. What is the best way to implement this in FME?Thanks 

Hi, I have many LAS tiles with gps_time component. Gps time values are in standard GPS Time : ex 363439432.1942503 I would like to display the minimum and maximum times in DD/MM/YYYY HH:MM:SS format. I can use the PointCloudStatisticsCalculator to get the minimum and maximum values, but I can't work out how to convert 363439432.1942503 to the required format. Any idea? Thanks u ! 

Hi everyone,I am working in FME and would like to orient the flow direction of a gas network.Data: main supply lines service lines connected to gas connections Destination  points – representing the gas service connection locations Objective:My goal is to ensure that all Service lines are oriented towards the Gas Service connection points.If a line is digitized in the opposite direction, it should be automatically reversed.Additionally, some lines connected to Service Connection points   are split into multiple segments. I need all connected segments to have a consistent direction towards the same Service Connection points .What I tried: I used the NetworkFlowOrientor transformer I applied a Anchoredsnapper beforehand to ensure that each

Hi, I want to import the WFS service from Digitaal Vlaanderen, specifically the address registry, but my FME only imports a maximum of 10,000 features.I had found that it was possible via paging, but apparently that is no longer supported, or at least I can’t find it. It should then be done via loops, but I’m stuck. I found that it should be possible using an HTTP caller and JSON fragmenter, but I’m already stuck with my HTTP caller. Could someone help me set this up correctly? The URL is https://geo.api.vlaanderen.be/Adressenregister/wfs?REQUEST=GetCapabilities&SERVICE=WFS      

I have attempted to use the NeighborFinder transformer to achieve a one-to-many join; however, it is not producing the expected results.In my case, the base dataset contains values such as 30,511 and 55,867, and my expectation is to match all records where the base value is greater than 30,511.Since NeighborFinder does not seem suitable for this requirement, could you please suggest an alternative transformer or approach to achieve this condition-based matching?Thank you. 

Hi FME gurus. I am trying to extract values from a list to populate columns with the associated values in the fields.  In my list (called _columns) I have a caption field which has the name of the column I want to create and the date value I want to populate into the field so the example I have in the screenshot I want to look like this: Application ID Last Inspection Next Inspn Due 648343 2025-06-23 2026-06-16 15456.. 2025…. 2026….  The list exploding only brings out the name of the original column ‘caption’ but I am looking to use the values in the list itself to build the attributes and populate the values. There are rec

Good day,I have a table with a couple of records.I would like to keep one record per category and this record should be the record which has the less attributes with a null (missing) value (I highlighted them in green on the screenshot.). How can I automatically calculate which record per category I should keep? 

Within the new ArcGIS Feature Service reader (part of the Esri ArcGIS Connector Package) if you choose a source type of Enterprise it’s not possible to connect to a feature service that is shared across an entire organisation and not in a group.This can be done if you use a Source Type of Standalone Server (but it’s not obvious).It would be nice to have and Item Source of Organisation which would allow connection without specifying a Group 

When using ArcGIS Feature Service (reader, writer, featurereader, featurewriter) I am only able to reference items using Folder and then featureservice name + itemid (in paranthesis after the name). Is it possible to directly refer to a service using only itemid?(for my case the data is hosted on my institution’s AGOL)

I’m creating a workspace that reads 7-8 tables from a file geodatabase and then writes them into tables in a SQL database.  One of the tables is sometimes present and sometimes missing (that is expected).  I need to create a workflow where when the table is present we write the data into the SQL table and when it is not present we just truncate that same table in the SQL database.  I currently have a gdb reader connected to a tester that passes when fme_feature_type Like MSAG_To_RCL_Synchronization. This works when the table is there but when it’s missing the reader just closes and gives the message “The table name 'MSAG_To_RCL_Synchronization' could not be found in the Geodatabase as either a feature class or a table” and closes before any input gets to the tester. Any ideas on how to conditionally test if a table exist or not and then either write the data or truncate a SQL table.
