Transformers

I have a glut of features of multiple types coming in from a handful of .ifc files. I am attempting to write a transformer as a proof of concept that will allow me to filter the features (currently 174000+) to different writers based on a small difference within their source filenames. Basically what I want to know is if it is possible to use the text editor to create an “if filename contains text (abc)” filter. If not, what would be the best way to filter for something like this.  

I need to use the PythonCaller because the area on area overlayer doesn’t work with my input featureset. I want each polygon in featureset A to overlay against all the polygons in Featureset B (which does not self intersect) and then drop overlays with NA values in specific columns. I found documentation for the fmeobjects.PythonCaller, but the documentation doesn’t include how to actually run the transformer.fmeobjects.FMETransformer — Python FME API FME 2024.1 b24615 documentation (safe.com)i.e. what do I do with f = fmeobjects.FMETransformer after I’ve set the attributes?Additionally, it’s unclear what the parameters are for this object, as there is no function definition returned to define what is required for each transformer type.

Is there a transformer that can create classes based on natural breaks, quantiles or equal Intervals?

I have a complex workflow where a specific attributes, i.e. “PositionID”, which are referenced across multiple transformers. I need to rename these attributes to another name throughout the entire workflow. Manually opening each transformer to change the reference would be very time-consuming.Is there a way to quickly rename this attribute in all transformers without having to edit each one individually? Any tips or tools within FME that can help streamline this process would be greatly appreciated.Alternatively, next time I create a project can I set these up as parameters or variables and reference them that way and hence change them more easily? Thanks

Hello,I am trying to start a workbench that uses data from my enterprise geodatabase. I have a feature class called WaterDevices and it has attachments. However, the FeatureReader does not read the relationship class. I attached an example where does read the relationship class in a different enterprise geodatabase for sewer.I’m not sure where to start troubleshooting this. Any advice would be appreciated. I’m on FME Form 2024.0.3.0.  

how to find the all paths between start node and end nodeexactly i have 8 nodes ,as point A,B,C;D;E;F;G ;Hi want to check the all paths possible what ever the length of path but i want to find any path available between every Node between Node A and the rest of nodes (B,C;D;E;F;G;H)then checck between Node B and the rest of Node (A,C;D;E;F;G;H)and so on ,i want to check between one node and the rest of nodesfor sure some of them has no connections liens ,i want to define that also which two nodes has no possible paths. i used shortest path finder but i think,it is working only to find the short path between path A and path B,but i want to find all possible paths between A and B even it is long or short and get the id of each line through this path . i prepared my network so all lines are connected without any gaps so i have now paths between some nodes and some not depend on the network .Thank

Hi friends,I am trying to do converstion from a vertices to lines that I am working on for a somebody. He use a GPS to track prarire dogs for his work.So I looked at the shapefile he provided me and it has no GPS. So I create them with the latitude and longtitude. What I am trying to do here is to use the LineBuilder here and then use writer to create a new shapefile…It came out nothing…What might I go wrong here ? I work for US agency and we have FME Desktop 2022.2 version. Do not ask me why. Thanks

 Hello dear community,For our student project, we need to provide an evaluation using the FME software. We obtain our data via a REST API, which has a limit of 500 records. The output is provided in JSON format, and the JSON is structured as shown in the code. { "count": 523, "totalCount": 523, "results": [ { "score": 0.3534, "object": { "id": "1234234", "type": "LO/LOV/LOVZ", "leikaKeys": [ "99005004114000" ], "name": "Reisepass beantragen", "teaser": "Zur Einreise in bestimmte Staaten benötigen deutsche Staatsangehörige einen Reisepass. Über die Einreisebestimmungen weltweit informiert das Auswärtige Amt auf seiner ...", "textBlocks": [ { "type": { "id": "835343545", "name": "Type (z.b. PostAdress, T

Which transformer can I use to identify overlapping polygons in a single dataset and show them as the output.

I have a very large dataset where all of the polylines have elevation that should be measure data.  The custom transformer ElevationtoMeasureCopier is such a memory hog that the workbench is failing on my computer and on my server.  Is there a different way to copy the elevation data to measures? 

I have two workbenches, in which the emailers fail every night, the error being:Emailer_<Rejected> (TeeFactory): Emailer_<Rejected>: Termination Message: 'Emailer output a <Rejected> feature. To continue translation when features are rejected, change 'Workspace Parameters' > Translation > 'Rejected Feature Handling' to 'Continue Translation''Error encountered while calling method `input'for the one that runs first, and:Emailer: <class 'TimeoutError'>: [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respondfor the second. First is an all out error that terminates the workbench, the second just being a warning, but the outcome is the same - no ema

I have a summary query with GROUP BY, HAVING, and ORDER BY clauses and I would like to send an email with the results from this query. My workspace can send html results of a query of listing all the records but that is not the summary I’m looking for. The Aggregator transformer doesn’t seem to have what I’m looking for either. Is there a way to send the result of this query shown below? My data is in SQL Server.  SELECT caseID 'ID', count(*) 'Count'  FROM my_table  group by caseID  having count(*) > 1  order by count(*) desc 

Hi everyone,I am currently comparing lines in database A and database B, and I want to categorize them based on distance from each other:If line A < 10cm line B → class 1If line A 10 - 30cm line B → class 2If line A < 30cm line B → class 3I thought I'd do this using the Clipper transformer: if part of line A is within 10cm of line B, and another part of line A is 12cm from line B, I want line A to be split. See my workflow below:I have my Clippers grouped by ‘type’ and ‘level’, so [railroads on level 1] are compared to [railroads on level 1] and [road lines on level 2] are compared to [road lines on level 2]. I have Overlapping Clippers set to ‘Clip Interim Results’ and I am generating a list of IDs from line B on line A. This is the situation im currently facing:

As title says, unable to convert lat/long to MGRS when latitude is -80.01 through -81. e.g., x= ‘100’, y= ’-80.1’ . I’m sure this isn’t the exact range but am able to reproduce the error.Was wondering if someone had additional information on how transformer calculated polar zones and, if there is preprocessing required for points located in south and north polar regions?Additionally, lmk as comment if you’re able to reproduce error in other FME versionFME Form 2023.2 

I am transforming an IFC file to CityGML to upload the CityGML model to the 3DCityDB. I used the workspace published by Liz (https://support.safe.com/hc/en-us/articles/25407718003341-BIM-to-GIS-Intermediate-IFC-LOD-300-to-LOD-4-CityGML). The CityGML file created looks fine in the FME inspector. However, when I try to import the CityGML into the database, I get a lot of errors saying, “Failed to resolve XLink reference”. I was doing some research, and it seems the problem is that 3DCityDB does not support a gml:MultiGeometry with different dimensions (This is what they mention in the GitHub: In general, a gml:MultiGeometry is a collection of geometries that are allowed to have mixed dimensions: points (0D), curves (1D), surfaces (2D) and solids (3D). The 3DCityDB can handle geometries

I have installed FME Server on a machine called "fmeserver-dev.com" and also used this as the hostname.Later we switched everything to SSL (including the Websockets) and the external web host name to "(https://)fmeserver-prod.com".  Now, everything (Web UI, Services, Websockets...) is working fine, except the Topic Monitoring!  Using the Developer Tools of a web browser, I have identified that there is still a parameter 'webSocketServerName' set to the old hostname "fmeserver-dev.com". This must be causing the issue as the SSL certificate is not configured for that domain. How can I fix this?

I am attempting to add a Geocoder transformer to spatialize address data using a published geocoding service on ArcGIS Server. When running the address data to the transformer, it rejects every feature with “Code 403: Access to this resource is not allowed”. The REST URL and Portal credentials are all correct and I am able to get to the service in a browser, as well as access and use the Locator in ArcGIS Pro to geocode addresses. With that being said, I don’t know why access to the resource would be disabled in FME but nothing else. Any insight or suggestions would be appreciated, thank you!

I need to warp some data, so I'm using the RubberSheeter. This works fine except that in certain parts of the data I also need to create a gap. In broad terms the situation is as shown here: I need to cut along a line (the red line) and then use the control vectors (green) to pull things apart, leaving an empty void in the middle. What I've done is use a Bufferer / Clipper to remove a little bit from the original feature, along the cut line. Then I've added a bunch of control vectors, making sure they don't start exactly on the cut line but just a little bit on either side. However, FME is still showing data inside the gap and I really don't want to have to manually edit that. Does anybody have a suggestion?

Currently the OpenAIVisionConnector (version 6) requires an OpenAI API Key and there is no possibility to adjust the endpoint.I hoped the transformer would be adjustable, but it’s password protected…I was wondering if it is possible to offer a setting where the end user can self set an endpoint. Bigger companies have the tendency to run their own cloud, and ours is no difference here.We for instance use Azure OpenAI, but with open source AI models e.g. Llama getting more and more capable there might be a valid point to give the end user the possibility to adjust the endpoint.It might be a bit uphill, but if there would be the option to chose between an API Key, and a Bearer token; that would be awesome!What do others think about that?

what can cause a process to run on the desktop and then restart on the server? have you had similar problems?

Is there a way to obtain a list of unchanged values then explode the list afterwards similar to how change detector can have an output list for changed values. Below is the sample workflow I’m trying to do but for unchanged values  

Hello to all,I have a problem with an IFC file where some IfcProperty are referenced by a propertySet but not defined. Then, I have a message like this : IFC: Could not find instance #245009 in the IFC file.So, my question is to know if it is possible to say to FME to continue to read the file ?Thank in advanceBest regardsBruno

Decoding the “outer” response body parameter value from the HERE Isoline Routing API I get a list of tupels with xy coordinates in this form:[(y1, x1), (y2, x2), ...].How can I convert this into a polygon? I have tried different approaches including PythonCaller scripts but cannot get the correct result.Alternative approach would be using the GeometryReplacer transformer which also supports the Encoded Polyline but also with previous crs setting to epsg: 4326, the LineCloser and AreaBuilder transformers the polygon geometry has a wrong location, without any recognised epsg in a Desktop GIS and the polygon geometry is also incorrect.Thank you!

Hi All,I’m testing a simple workbench to fix the geometry of a SHP thought ArcPy RepairGeometry in FME PythonCaller. Here’s is the simple code to run in FME but for reason fails:FME_MacroValues['SourceDataset_SHAPEFILE']The idea is running the script before writing the data into a GDB,Any idea how to make it to work?Thanks :)
