Transformers

Hello Safers,I have a layer of tie points, and another layer of line segments. I was wondering how would get FME to snap segments to these tie points? I believe I have to use the line extender, and intersector without incorporating my tie points. Or, is there another way? Basically, I have roadcentrelines from various locales and I have to snap lines together from them to make an unified dataset. Thanks!

I have a new attribute named EXPORT_YEAR. I want the Attribute Value to automatically change to 2026 at 12:00AM Jan 1, 2026. Until then it will stay 2025. Is this possible? if yes, what expression do I use?   

Is it possible to save the frame of the data inspectors?I mean, I have this:Two layers overlappedIs it possible to save this image at certain zoom directly in FME from data inspector or the regular translation environment?

Hello FME Community, can someone help me configure the Geocoder transformer to use our County geolocator service?  I’m using a single-line address, with the locator on an ArcGIS Server.  The URL is https://gis3.montgomerycountymd.gov/arcgis/rest/services/geocode/Composite_Locator/GeocodeServer.  This is a public-facing locator service for Montgomery County, MD. I’ve tried:   Using the above URL   Using the locator as an AGOl item in the transformer, both fail.     Setting the URL with different paths to the operation or the base geocode folder.   Setting the transformer geocoding service parameter as ArcGIS Server or ArcGIS Online.  I can successfully use the geocoder transformer with the ArcGIS Global geocoder, but I prefer the County geocoder to ensure the addresses and inters

@safe I just recognized that the SpatialRelator in 2025 does not release my Requestor attributes as before (2024 and any older version I remember).I’m used to use the SpatialRelator with the setting ‘Generate List’ checked (incl. some selected attributes) and keeping the ‘Merge Attributes’ unchecked. As a result I see all my Requestor attributes and where applicable the list attributes according to the spatial relation I’m looking for.Now in 2025 the above setting ONLY releases the list attributes and all my Requestor attributes are removed. The only way to bring it back is to check the ‘Merge Attributes’ checkbox as well, which is not my intention.I guess it’s a bug since the Transformer page still states for ‘Output’: These are the Requestor features with the new attributes added. One list entry is made for each of the Suppliers that has at least one matching predicate. FME Form 2025.0 build 25208

Hi, I have 50 SQL queries stored in a excel file.Column A: Name_SQL_QueryColumn B: SQL_QueryI am having a hard time find ways to execute the query and export to a CSV file with Name_SQL_Query. I set the csv writer to dynamic exposed. however, when i run the workspace i only repeated sql 6016 times (this is the number of rows I get when i execute the sql by itself). it seems like the first Query from the excel list is working when i sampled the first 1. However, I am getting the repeating of column A and B. How do i export the result straight from the SQLExecutor?  

Hello,Do you know why autocad_color parameter is allowed from 0 to 256 for Autodesk Autocad DWG/DWF writer but is strictely limited to 1-255 for Autodesk Autocad Map 3D Object Data writer ?It prevents to write entities with ByLayer (256) or ByBlock (0) Color parameter in addition with OD tables 

Hello everyone, I’ve been working with 3D Buildings recently and I’d like to add some info to the walls (e.g. indicating which wall has an entrance door). I could set up this information with the 2D Footprints by using the BoundingBoxReplacer and HorizontalAngleCalculator (I’d have used it with my 3D Buildings themselves, but it only works for 2D lines). But I can’t find the right way to add this information to my 3D walls.If I directly extrude the 2D walls instead of the 2D polygons, I lose the classification of Building_IDs that I want. If I reconvert the 2D walls into 2D polygons with an aggregator, all my info goes away and I’m back at the starting point. I tried converting the walls into points with snipping and then converting them into 3D Features with Offsetter and Bufferer such as other pas

Hi, wondering if anyone know how to limit the featurereader, I am trying to read only the first 10 rows from each table in postgres and it is still pulling back every row before passing on only 10. What am I doing wrong? Thank you in advance

I wish to use the JPEG writer rather than the attribute file writer, because I want to add EXIF data to the image that doesn't exist in the original BLOB. I do not see a way to add this EXIF information when simply using an attribute File Writer.

I have two lines that are starting from the same point (blue point). I would like to calculate the geometry of the points where the lines start to run in parallel (approx. where the green points are). How can I do it in FME ?

Is it possible to force a custom transformer to process features one at a time when there are blocking transformers within the custom transformer?I run into this problem when I try to create a 3DGeneralizer and want to process lines individually.Example: A custom transformer splitt lines into vertices. The lines are also generalized. NeighborFinder is used to match vertices and generalized lines. I want the NeighborFinder to only process features (line and vertices) from a single line at a time. If Group By is used in NeighborFinder it will block features until all lines have entered the custom transformer.Thanks, Anders

I have a template.gdb that contains feature classes, and some attributes within these feature classes have default values. Like here for the attribute FLOWDIRECTION When writing features into these feature classes using the Feature Writer, I expect the default values to be applied to attributes where no value is provided. However, this is not happening. What could be the reason for this issue? How can I ensure that the default values from the geodatabase are correctly applied?

Just recognized, after migration of a workspace from 2024.2 to 2025.0 a BulkAttributeRenamer shows strange results: The transformer is set to change attribute names to lowercase (mode rename) for a selected set of attributes. This works as expected. However the remaining attributes (not selected for any change) got almost completely removed. ‘Almost completely’ means from the >5000 records only 4 have the attribute after the transformer while all other records show the attributes as <missing>.@safe - although it’s easy to mitigate it might be worth to dig into it.note: in mode ‘keep original attributes’ results are as expected.Klaus 

Hi, we are searching for a solution to create seamlines between aerial photos.So we have a lot of photos with different overlapping areas like this:footprints Is there a possibility to create seamlines between the images? So we wouldn´t like to do this manually. It should be approximately the center line of the overlapping areas. At the end we wanna cut out the origin arial images based on the seamlines. Does anyone have experience with this?  

Hi all,I work on a mapping project that requires all of our shapefiles to be quality checked at the end of production. I currently have an FME workbench that converts Esri geodatabases to shapefiles for the final check.However, I’m having an issue with one of my attributes. The attribute is being written out by the workbench as a ‘double’ (which I believe has a max width of 19). The quality check tool checks both the data type (needs to be real) and the specified width of each attribute (needs to be 19).When it is checked by the quality check tool I get an error message which states the expected length is 19 and has found a width of 15? It’s fine with it being a ‘double’ though?Any ideas?Will provide more information if needed.

Hi,I am trying to use the SpatialSorter in my workspace to sort data by location and define group size. However, as I’m currently using the FME Workbench 2024 version, the SpatialSorter is quite different and doesn’t provide a new attribute named “GroupID”, it’s also impossible to define a group size in the parameters.It is quite inconvenient because it’s not possible to use the Aggregator transformer on the GroupID attribute afterwards to group sorted spatial data.As far as I know, there is no unexposed attribute generated from SpatialSorter in the FME 2024 version. To compensate, I used the  NeighborhoodAggregator but I’m not satisfied by the results.I was wondering if anyone else encountered the same issue and found another solution ? Thank you for reading!

I have a workspace in FME 2021.2.6 where I produce a TIN from a DEM with the TINGenerator. In this transformer there is a parameter called Tolerance. I was playing with this tolerance to find the right amount of detail, that is still acceptable for my task and reduces the amount of triangles in the TIN. Now we’re about to switch to FME 2025 soon, so I thought there might be a performance win with the new Version, so I gave it a try. But I found out, that this transformer does not work the same way anymore and whether I put in 1 or 100 or 10000 in the tolerance, it does not really matter. The result looks way different and in my opinion is worse, than with the 2021 version. Can someone explain me, how I can produce kind of the same results as with the 2021.2.6 Version? How can I reduce the number of produced triangles and level of details within the TINGenerator if the tolerance does not has any effect on this?Thanks for your helpSimon Different tolerances

The two lines below share the same end nodes and I want to give them a common group id for later processing. This is to be the step after a TopologyBuilder.I thought this would be pretty simple, but have run aground. So how do I achieve this?The geometris are to be left unchanged. I just want them to have a common “id” if they intersect at both ends.The conditions for the ‘join’ are:_from_node = _from_node AND _to_node = _to_nodeOR_from_node = _to_node AND _to_node = _from_nodeBecause sometimes the lines orient in different directions.  

Hello, Has anyone ever created an ArcGIS Pro layer file *.lyrx inside FME for use in ArcGIS Pro? For example, converting a *.dwg file into *.gdb, aswell as creating a layer file which holds the symbology from the *.dwg. Thanks, @Takashi Iijima​ @danilo_fme​ @Hans van der Maarel​ 

In postgis i can flatten compound geometries like soSELECT ST_AsText(ST_CurveToLine(ST_GeomFromText('COMPOUNDCURVE (CIRCULARSTRING (576285.49817038781 7034469.7208286244, 576325.10797829565 7034483.5911118472, 576367.02 7034485.76), (576367.02 7034485.76, 576396.53 7034483.05), CIRCULARSTRING (576396.53 7034483.05, 576447.15568394249 7034473.94116881, 576495.46 7034456.26, 576500.76470677822 7034454.0120333815, 576506.21 7034452.13, 576508.88920362911 7034451.3602161128, 576511.59 7034450.67), (576511.59 7034450.67, 576517.82000000007 7034449.45), CIRCULARSTRING (576517.82000000007 7034449.45, 576521.86965882347 7034448.9300352931, 576525.94000000006 7034448.61, 576543.62140925834 7034449.5502338214, 576560.694903961 7034454.2419341141))')))But how do i do the same thing in FME?ArcStroker can only flatten Circular strings, but not compound geometries?

I had a look at this documentation:gtfs-measures/docs/GTFS_Script_Documentation.md at master · VolpeUSDOT/gtfs-measuresAnd it is exactly what I would like to do in FME. I already found the script to create lines from shapes, routes and stop text files, the problem is that those lines follow the stop coordinates. I need it to follow an existing road network. I couldnt get the Python script to work and it is pretty old as well. I tried snapping the bus stops to the road network before I run the script, creating a bus_stops_snapped but it still doesn’t really follow the road network. Any idea of how this would be done? I have the road network as both shp or geoD

Hello everyone, I'm currently imitating this example from FME to generate 3D buildings from 2D polygons, but with my own data. I expected that, being 4 perfect squares, I'd get 24 tiles after running the deaggregator, but instead I have a few more.It looks like some walls have been wrongly divided. I need to "simplify" these parts into an unique wall or else the appearence setter will not correspond.
