I wanted to make all my attribute to camelCase, currently they are separated by underscore.I wanted to change my attribute name to camelCase, so using regular expression in BulkAttributeRenamer transformer to find text following underscore using regular expression replace: _([a-z])  However, i am not sure what String parameter i have to put to make the selected character Capital letter. I have tried \U\1 and also few other but its not working. Basically wanting to find String parameter value? 

Hi, What is the best way to manage the schema drifting issue? Context: Currently the user uploads an Excel File through Workspace apps, and the file contains multiple attributes where the attribute names can change anytime. ID can be reported as Id, Identifier, id, ID. What is the best way to map and standardize these attributes ?

I’m using the Gemini Connector (Transformer) in FME and facing an issue with initiator (upstream) attributes.My requirement is:The attributes coming into the Gemini Connector (initiator attributes) Need to be merged with the Gemini response/output, so that the final feature contains both the original attributes and the Gemini result Current behavior: The Gemini Connector output only contains response-related attributes Initiator attributes are not carried through or merged automatically Question: Is there a supported way to merge or carry initiator attributes along with the Gemini response? Is this a limitation of the Gemini Connector transformer? What is the recommended pattern (FeatureMerger, Joiner, correlation ID, etc.) to achieve this? Any guidance, b

Hi,I have text from a source DWG that contains all the information needed to create an annotation class in a geodatabase (text size, rotation, color hex/RGB/fme, etc.). I’m able to create the annotation class in the GDB, but all the text comes in as black, even though the original text has different colors.What am I missing?

Hi,Is anyone else having issues with Form not starting after the recent Windows update? A repair did not help, and even a fresh installation of version 2025.2.3 will not start.

lets say I have a set of coordinates x1,y1 and x2,y2 how can i create a dwg with dimensions between these coordinates?if possible a step by step guide with the transformers/writers required for this.  

Working in FME Workbench v.2024.2I am working on a process that validates my metadata format and converts it if needed, then exports the final format to xml for backup. We are trying to ensure all of our metadata is in ISO 19139, but we know some feature classes are FGDC CSDGM Metadata. We would like to use FME to convert the format and then update/write to the existing feature class's metadata in our enterprise geodatabase with it. Secondly, we want to also create a backup of the xml file which will be saved to a local folder. I have done this using an "Attribute File Writer" and only writing the geodb_metadata_string to a .xml file, however, when trying to reimport it into ArcMap/ArcGIS Pro I receive a "Failed to import metadata" alert. Comparing it an export directly from ArcGIS it is clear they differ. It seems like FME is converting it to their own format when reading it in.Any suggestions on either of these processes would be appreciated, thanks!

Hello all,I would like to automatically record different Output Port names ​​into one new attribute. So in the newly generated output file there is al column with the name of the Output Port and a column with the value from the TestFilter.Desired outcomeI know it is possible to do it by hand, place a AttributeCreater behind every port and fill in the Output Port name. But I have a large number of TestFilters, and to avoid errors and keep things organized, I would like to do it automatically with one AttributeCreator/AttributeManager.If the AttributeCreator/AttributeManager is not the correct transformer, or I need two other transformers that do the job, that would already make a big difference to me.  

We recently upgraded our FME Flow from version 2019 to FME 2025.2.1. Although we encountered several issues during the upgrade, the system is now running. However, we are facing a new error when executing an existing workbench. The workbench reads data from an Oracle table and generates GML and GeoJSON files. The files are generated successfully, but at the end of the process, the following error appears: 190 2026-1-20 14:33:00 | Router and Unexpected Input Remover (RoutingFactory): No geometry mapping entry found for 'fme_line' in metafile 'E:\Server\fme\metafile\ORACLE_SPATIAL.fmf'. Please visit http://www.safe.com/support Has anyone encountered this issue before? Any guidance would be appreciated.  

Greetings everyone,I have a large number of 2D polygons for which I want to determine the Z value. I also have a DTM (digital terrain model).Now I have observed the following: If I take only one polygon and, using the FeatureReader, read in only exactly those triangles of the DTM that are touched by the polygon in 2D, and then determine the Z values of the polygon using the SurfaceDraper (always carrying forward only z_max and using that as the Z value via the 3D_Forcer), I get different Z values than when I first create a buffer around the polygon and then pass the buffer to the FeatureReader and include the triangles around the polygon in the SurfaceDraper.The triangles from the DTM do not touch each other.There are deviations of several meters, depending on how strongly the terrain height varies around the polygon.It seems as if the SurfaceDraper somehow takes the surrounding terrain into account, even if it does not touch the polygon.It

Is there any chance of getting a search bar added to the forums?  The forums are very useful, but would be even better if we could search on previously written topics

I try to find a text ending with a newline. Using the inbuilt regular expression editor (with the regex #! <DATASET\n) shows a result so the regex looks correct to me:StringSearcher unfortunately doesn’t find the line: (see attached workbench)Where are things going wrong?

We require support to establish a structured version management and governance process for FME workspaces (.fmw files) using Azure DevOps (ADO).Currently, FME files are updated manually, which creates challenges around version control, traceability, rollback, and collaborative development. We would like guidance and support on leveraging ADO repositories and pipelines to manage FME files effectively.The objective is to: Maintain version history of FME workspaces Enable controlled check-in/check-out and collaboration Support rollback and auditability Align with enterprise DevOps and SDLC standards Please advise on best practices, recommended repository structure, branching strategy, and CI/CD considerations (if applicable) for managing FME files in ADO.

Hi,I have a very simple workbench that is cliping a gpkg containing mulitple layer. I am struggling with writinng them back to one gpkg using dynamic schema. it fails every single time  

I am reading the feature classes and tables from an Oracle Reader, and many of those are not having any records, the tables are empty. But I want all of those in my ESRI FGDB output which I am using in the Feature Writer dynamically. How to achieve this? Any leads?

Hi,  Has anyone else noticed that when you use an attribute creator in your model, or renamer, or in your manager where you reuse an existing field, it works perfectly in your model but is not transferred when you write it to your shapefile? I always have to use a separate creator at the end This used to be no problem at all. I am now using 2025.2, but I had already noticed this in version 1.

Yesterday, after completing a first draft workspace, I showed my canvas to a colleague and they commented on how bizarre 🤢 my transformers appeared.I’d been painstakingly aligning my transformers by port - so that the output of a transformer would lead directly into the input of the following transformer. This creates flat, linear connections … but the transformers themselves don’t necessarily align. What’s your preference?  Check out your options here:  Arranging Objects on the Canvas

Greetings everyone, when taking FME Certified Professional exam on Talview, is it allowed to make use of AI assistant on the FME Workbench/FME Form?

I have noticed some folks including “FMEP” after their name on LinkedIn. I assume this is a designation that they passed the FME Certified Professional exam.Is this a generally accepted way of indicating this certification? Does Safe have guidelines about using this abbreviation?

Hi All,I hope FME will clean up posts after this…In Australia and tried posting on the 26th, 27th and 28th(today).I struck out on the ‘Are you smarter than ChatGPT’ quiz… the timed aspect was a killer. 

Hi All,Just after the August Calendar Badge in Bingo.“Did you know that each month has a specific date on which posting earns you a special community badge? To complete this square, simply earn the badge for August.” Does anyone know if it is timezone specific?

Probably splitting hairs here but I’m wondering what peoples preferences are for Tester vs TestFilterI have a Tester where I’m testing for someAttribute = someValue. this is case one. case two is where is fails the test.As it is on it’s own it’s not clear at all why or what the point of the test is. Using a TestFilter would let me define the output port names making it much clearer as to the purpose of the test without needing an annotation.Thoughts? Does anyone do this for the sake of clarity in a workspace?
