FME Form

Hello FME-Communtiy,With the advent of the new IFC-Writer we wanted to update and hopefully slim down our FME Workspace, which reads Multipatch Geometries via an Esri Geodatabase (File Geodb) Reader and writes IFC-Features via an IFC XML/STEP (deprecated) writer. Sadly we’ve not managed to get the new writer working as needed and have found the documentation rather lackluster, which is why I’d appreciate any pointers from the knowledgeable people on here.The new workspace has managed to correctly export the feature geometries, but the attributes seem to be missing/not written at all. Inside the new Workspace the features have the correct attributes and values up until the very end where they are sent to the IFC-writer (In this Case I tried Slab as the Element Type, BuildingElementProxy gave the same results and SpatialZone doesn’t work at all anymore).New Workspace final export inside Data Inspector (red color intentional)Old Workspace final export inside Data InspectorIn the old Works

Hi there, I have about 230 workspaces that run daily to import data using the ArcGIS Feature Services Reader. The issue is, with every run I get warnings that don’t seem to be a problem, but make it seem like the workspaces aren’t running right.NOT changing coordinate system of reader identified by keyword `SAFE.ESRI-AGOL.ARCGISFEATURESERVICE_1' from `EPSG:7844' to `LL-GDA2020_FME' -- mapping file setting of `EPSG:7844' overrides coordinate system `LL-GDA2020_FME' read from fileThis warning just seems to be stating the coordinate system will not be overridden by FME’s LL-GDA2020_FME Coordinate System. It is logged for every reader feature type ArcGISFeatureServiceReader: Querying feature server 'https://public-services.OrganisationURL.com/public/rest/services/ServiceName/MapServer/This warning should not be a warning in my opinion, as it's just stating that the reader is querying the feature service. This occurs once for every reader feature type as well. Debugging is disabled, however

Hi,So I would like to try to work out a point source ID for point clouds based on continuous chunks of time. Basically separating out flightlines. For example, a point should has 30 points. The first 10 are collected in the first 10 seconds, then there is a gap of 1 minute before capture, and then another 10 are collected, then another minute gap, then the last points. So in this case I would like to determine a unique component value for each of the 3 time related groups.I think I can do this if I coerce the cloud to points. But that really isn’t efficient for billions of points.I also won’t know beforehand how many different continuous capture periods there are.Can anyone think of a way to do this? It’s pretty easy to do in lastools. But in this case I’d like to do it in FME. I don’t know any python which I presume could do it.I am ideally wanting this to work in version 2022, but I’m open to a newer version if that is the only chance of doing this.Thanks

I have this data that I want to be treated as immutable (read as strings) in the format CSV (but i suspect that this issue is true for other formats as well?) but FME keeps auto format it to a different format. I think this started with FME 2024 or possibly 2023. Since then I’ve somewhat changed methodology for new work spaces, but yesterday a revisited an old WS and got reminded of this source of frustration. I hope that someone can cure this case of “excel-autoformat-hell” with a solution or an explanation? I really don’t want my data changed automatically in any shape or form.Example.CSV-file states that attribute “Datum” has the value ‘2026-05-20’ FME (CSV) reader keeps format it to  ‘20260520’. Even if i manually change the attribute to data type string or varchar FME still formats the date according to above.

Hi, I have two local authority boundary datasets that should align along a river but don’t and this is causing the Master Lookup between the two boundary datasets to be wrong. These two should be aligned and coterminous. How do I easily solve it? 

Newer versions of FME Form can be connected to FME Flow for the purpose of obtaining Deployment Parameter values at runtime:Given that FME Form is connected to Flow I was wondering if anyone knows of a way of obtaining details of that connection when a workspace is run in Form. It does not appear to be exposed anywhere.A workaround would be to create a Deployment Parameter in my Flow instances and reference that in Form but it seems there should be an out of the box solution to this.Specifically, what I want to do is to query the FME Flow API for the connected instance, without having to hard-code the FME Flow URL in the HTTPCaller.

Please create an FME option to connect to GCP (Google Cloud Platform) using “Workload Identity Federation” method in addition to Service account (current option).Thank you!

Hello everyone,We just upgraded to FME Form 2024.2.1 and we currently encounter one problem. For the users, the personal database- and web connections were inititally not migrated. Thus we sent first a mail to the users that they coud export the database- and webconnections in FME Form 2023 and then import  the exported file in FME Form 2024. It looked like it solved the problem, however when the users logged in the next day on an new machine, they lost all their personal database-  and webconnections.We read the following link: Changes to Connection Storage in FME Form 2024 – FME Support Center and it became clear to us that's due to the new way that personal database- and webconnections are stored. They are stored in fme_userconnection.data and the machineID is hardcoded in this file.In our organization we work on a virtual machine and thus also everytime we log into a new machine. It's now clear why the database- and webconnections are not visible in FME Form 2024.I was wondering if

Hi All,I’m trying to calculate volumes on meshes in a dgn file. The dgn file represents rail embankment / earthworks (ballast, formation, etc.). Below a screengrab of the design:My current workaround is DGN Reader → SurfaceBuilder → SolidBuilder → VolumeCalculator but am finding that some of the meshes are not closed. Before calculating any volume I need to close the meshes but can’t work it out,Any idea about how close the unclose meshes? Thanks!

Hello,I I am fairly inexperienced with some FME processes.My task at work is to extract text from DGN files and convert it to Annotation Feature classes in a GDB. I need to override the FontSize value that comes from DGN with a specific value in the GDB Annotation class, and all my attempts failed. Does anyone have suggestions on how to go about it? I am using FME 2024 and ArcPro 3.5. Thanks! 

I have a workbench with a RasterMosaicker that runs fine in 2021.2.6, but the same workbench throws an error in 2025.1 “Failed to mosaic the rasters”. Same error for version 2024.1.2.1.The error occurs only when setting the parameter “Overlapping Values” to “Composite Using Alpha Band”.Is there anything known causing issues regarding raster transformers in newer versions that might explain this?

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 into the H3HexagonIndexer (https://docs.safe.com/fme/html/FME-Form-Documentation/FME-Transformers/Transformers/h3hexagonalindexer.htm) but can’t get the results I’m looking for / work it out. Any ideas would be welcome. Thanks,

Can fme only run up to citygml 2.0?I don't know the part about uploading citygml 3.0. 

When a database is updated using SpatialRelator, FeatureTypeFilter, and DatabaseUpdater Transformers from feature classes inherited from two different readers, the _relationship attribute disappears when the FeatureTypeFilter Update button is used. All DatabaseUpdater transformers are in the "incomplete transformer" status. When examining the DatabaseUpdater transformers, the _relationship values are red. Copying and pasting the same value fixes this. To avoid this issue, you must manually edit the FeatureTypeFilter, which is time-consuming.  

Basemapping available to our org is limited. Several are dark or the level of colour obfuscates point geoms in particular. Can we have a basemapping transparency/colour intensity setting?

Hi,I was hoping to use the new IFC writer available in FME 2026.1 to update the IfcPresentationLayer attribute values from IFC to IFC.The idea was to disregard the current layers exported from Revit from others and define our own layer presentation for the models so we can turn certain layers on and off in our platform (Trimble Connect). I used the reader to load the IFC file (in 2x3 format), and it successfully retrieved all layer attributes into FME. However, I don’t seem to be able to write the updated layers.In fact, even without adding any transformers—just using the reader and writer from IFC to IFC—the layers are lost. So I’m wondering if anyone has had success using the latest FME reader and writer for rewrite the layersThanks!

We are working for a client that has a test domain and a production domain. Servers in test cannot reach servers on production and vice versa. There is currently an installation of ProjectWise (PW) installed in both domains, but the test version is a minimal installation that lacks WSG being setup and configured whereas the deployment on production has everything, currently.Our task is to setup a process that will use FME Flow to retrieve DGNs from PW and use them elsewhere. We currently have an FME Flow installation on the client’s test domain and are trying to approximate the workflow that we will have available to us in production. However, for the moment at least, it appears that WSG being installed is a core requirement for reaching PW with FME. We have other methods for users to place files where the test FME Flow server can reach them, but I would like to know if there is a workaround that can get us to our final goal prior to putting it in the production domain.Any help is appr

Hello,  it is possible to see a FME workspace CPU usage at the end of a job in the logging. However, when you activate a stream it will occupy an Engine and it will not give CPU usage in the logging. Is there a way to find or register the CPU usage of a stream that runs 24/7?

For a specific Writer (for example Precisely MapInfo Extended TAB)Is there a way to see a history of changes and improvements from version to version of FME Form?I have v2022.1 installed, and I am researching if the Writer has changed or improved in v2025.I am aware that a Transformer has a version number specific to that Transformer, but a Writer’s version number is locked to the version number of FME Flow, so it is hard to quickly determine if the Writer has changed between versions of FME Form.

Hello, I have a pointcloud scan of a underground tunnel. I would like to calculate its volume. Is this possible? I am guessing I first need to make a water tight mesh out of it. Kind regardsMathias

Hi,I’m looking for solutions to a problem that may not be solvable.I regularly need to refer to a spreadsheet from the NZ Electricity Authority (it’s open data).  At the moment I have to regularly download it from https://register.ea.govt.nz/ using the ‘Download’ button This downloads a dynamically time-stamped spreadsheet of the electricity industry participants and their relevant codes.I want to automate this with Form/Flow but this is a sticking point.  I’ve suggested to them that they expose this as a service for the industry, but the wheels move slowly if at all.Any idea on how to read, or more likely, automatically download this?  For the download I’m open to non-FME automations.Thanks

FME Form Excel writer warns of reserved characters, where none exist, in the names of my Named ranges and appends underscores to them. I am getting a lot of warnings similar the following:Excel Writer: Feature Type '/AH_4_3_Housed_Part_Time_Replacement' has been modified to '/AH_4_3_Housed_Part_Time_Replacement_' to avoid reserved characters for Named Ranges and Tables in Microsoft Excel This is unhelpful behaviour, can I avoid it?2025.2
