How to convert polyhedralsurfaces(voxels) stored in database with addtional attributes stored in columns into cesium 3dtiles?Additionaly to export the data in a suitable format to view voxel and its attributes?

Hi Everyone, I’m kind of stuck with a problem with my Geopackage writer. For a client, I’m working on building a script that generates multiple Geopackage tables, each with its own name. Each Geopackage table writer uses a fanout to automatically provide the writer with the needed file name. The writer also uses a Geopackage with styling embedded in the database, with 0 features, as a template file. This template is provided by an engineer from the team, which should automatically style the Geopackage based on the attributes it has. The problem occurs when I have both fanout and template file enabled. This causes the Geopackage to only write certain features. I can’t find any logic behind why it writes some features and not others. The template file and the Geopackage writer are 1-to-1 copies of each other, and I get no errors/warnings regarding feature issues. For example, one table, which consists of 470 features, will write 233 features, a

  Im fairly new to FME, I have a programming background, and I was hoping to bring those skill here, but i can see is not fully the same. So I apologize before hand 😂 I have a custom transformer that does a API calls and loops until it finds “last-batch” set to true from the Header area. For Reference Here is the custom transformer:The first call uses uses the InitialHTTPCaller, which uses the the request url and access token from the main workbench. Here is a screen cap: The _response_header list will have the variables I need to determine if the its the last-batch = true and the next batch url. 

Hi,Does anyone know of a method where I can readily identify which transformers are affected (ie need an update / fixed / superseded!) when updating from one version to another?Whilst I know there is documentation with each release, is there an easy way to compile a list that could be read into a workbench?I am also aware that each transformer has a version number.I want to create a method for identifying which workbenches are going to break before updating the software!I am hoping someone has already thought of this and the solution is already built… Any help much appreciated.Stu

Hi Im using the AGOL feature service writer to write to our AGOL account but it is not working correctly. The workbench reports that it has been successful with the correct number of features. However, when you open the item in AGOL, there are features missing. The last one I tried had 80k reported to have written but only 4k in AGOL!If I use write a fgdb locally and then the ‘ArcGIS Online Connector’ transformer to upload the file and another to publish it, it works fine. However, I cant work out how I could use this to do updates to the hosted feature service when the data changes (Ive got this sorted with the writer)Im using FME 2023.2 (dont really want to upgrade until 2025.1 is out as its a proper pain to upgrade server) but if there is an issue with the older version of this transformer I will.Does anyone know why the writer is not working but the connector is? This data is business critical so I need to ensure that it is correct.Thank

Hi,First off, excuse my ignorance in this question - im a beginner. Please let me know if any additional details would be helpful.I am using the HTTPCaller transformer to run a print POST from an AGOL app (Experience Builder).I’m able to successfully run the HTTPCaller and pull the response_body containing the output pdf URL. Id like to now run another transformer to download that pdf locally. Any suggestions on the next transformer to achieve this? An example of the URL: https://utility.arcgisonline.com/arcgis/rest/directories/arcgisoutput/Utilities/PrintingTools_GPServer/_ags_mapfile_name_hear.pdfMuch thanks!

Hi,I need to find the average distance of 25 nearest neighbours in a point layer. I have tried with Neighborfinder set to 25 number of neighbours to find and generate a list, then a ListExploder to expose the list, but I don't know how to group the 25 neighbours to calculate the average distance of these 25 neighbours to the base point Im gettin this of ListExploder: idRecord it’s the ID of points.Any ideas for grouping the 25 neighbours to calculate the average distance?Thanks you all.

Hi guys!I'm trying to export a list of the completed jobs using the FME Rest API, but I can't seem to get it done. What I want is basically a list of all the completed jobs, including the start time, end time, job id, engine, workspace name etc. For this, I'm using FME Form, a creator connected to a http-caller. Used the following Request URL: /fmerest/v3/jobs/completed?status=SUCCESS/fmerest/v3/jobs/completedAnd a few others.I got two headers, one with the token and one with the content type.The errors are being returned:{"message":"null for uri….}Does anyone know a solution for this?

I'm trying to use RasterClipOverlay to extract an area on GeoTIFF defined by a polygon.  FME is currently giving me the incorrect area.  The Workspace: The workspace has a polygon coming from a POSTGIS layer which is filtered. It also has an GeoTIFF  both of which are inputs to the RasterClipOverlay.  The results are output to a GEOTIFF.  As a test I have also added a simple output image that does not come from the RasterClipOverlay. Both the polygon and image are in the same projection EPSG:3395.The original image (displayed in QGIS):   The polygon (in QGIS):

Im wanting to see the http it’s generating so i can understand where its going wrong. Is there a way to see this - without it being submitted? Or even if it’s being submitted? Im sure im missing something. JKW

I am using FME Form 2024.0 to read an excel file for processing.  The reader is not determining the correct max length of multiple text fields in the XLSX file.I have set the max rows to scan to a value larger than the total row but short of manually setting these values I cannot get the reader to detect the correct field length.The FME Help for the MS Excel Reader states to leave this setting blank to scan all rows but the transformer will not except a blank value.I also tried to use the FeatureReader rather than a standard Excel Reader wit

Hi,How can create a published reader parameter for gdb feature classes?The gdb conation Point, line Polygon feature 

Apparently this feature was finally introduced 5 months ago, yay. I’ve been waiting for this for 5 years.I’ve just tested it today, with a PKCS#12 certificate, and unfortunately it doesn’t work.We’ve sofar been using our own C# service provider for this, and the certificate is used here on a daily basis with success. And I’ve verified the private key password.Has anyone tried this feature (with PKCS#12) yet with success ?Using 2024.2.3 (build 24825).Cheers.

Hi All,I have been trying to put a workflow together to linear referencing a few event tables in GIS. I usually do the task in ArcGIS but this time I want to automate the process as much I can.I have been checking a few of the LRS FME tutorials online but can’t get it to work. The aim is to linear referencing speeds along a railway route (line) using an event table that relates the lines and speeds.The input of my workflow as follows:Event table (xls) that shows the Line and speeds, example below: Line geometry with the line ID as well the ‘From_Chain’ and ‘To_Chain’ fields as parts of the attribute I have got to this point i

FeatureReader setup with a parameterized connection.If an incorrect connection is selected, the errors are reported “The error number from ArcObjects is: '-2147216100'. The error message from ArcObjects is: {Insufficient permissions” But the workspace doesn’t terminate and nothing exits the rejected port of the FeatureReader. Rejected Feature Handling is set to Terminate Translation. I would expect the workspace to fail/and or output from the rejected port on this sort of error FME 2024.1 (Form & Flow)

Hi, I just upgraded FME Form and FME Flow from 2024.0 to 2024.2.3. One of my jobs failed using a FeatureReader with the Directory and File Pathnames due to the extension not being in all caps because the extension on the file it’s looking for is in all caps (.CSV). Originally the parameter was set to filename.csv and the FeatureReader would have no issues finding the file on 2024.0. Now the FeatureReader is not able to find the file in 2024.2.3. I changed the parameter to all caps .CSV in the featureReader and it finds the file with no issue. Anyone else noticing this with 2024.2.3? 

Hi All,I have a survey asking participants to rank their favourite colours—Red, Blue, and Green—in numerical order (1, 2, 3).I want to use the results to create a workflow that counts how many times each colour has been picked based on the ranking.Here is some example data.Sample Data Unique_ID Colour Rank 1 Red 3 1 Blue 2 1

I have a feature reader that’s reading an Oracle non-spatial database. I have a workbench that writes all of the read tables to a file geodatabase. Some tables, I process twice; one where just the flat table is written, and another where the coordinate attributes in the table are used to create a point feature class written to the same file geodatabase. For some reason, only the flat tables are being written and none of the point feature classes are being created. Both work if I run them separately but not if I have two coming out of the same reader port. I’ve hidden the lines to write the flat tables to the feature writer.Is there a setting in the feature reader that I need to change to ensure it processes multiple outputs for each feature?  

Hello there, I am trying to execute some Python using the ArcPy module in a workbench base on this Tutorial, Using Arcpy for FME Feature Processing, but I am getting this error the following error:Geodatabase Error (-2147220970): Cannot acquire a schema lock because of an existing lock.Could not open File Geodatabase dataset `C:\Users\’USERNAME’\AppData\Local\Temp\wbrun_1740499345598_2444\fmetmp_24\1740665793794_2528_d\tor470\temp.gdb' for readingFailed to obtain any schemas from reader 'FILEGDB' from 1 datasets.

Hello FME Experts,I am working on processing a point cloud and need to create height-based sections to later filter the point cloud accordingly. Here is my goal:Extract the minimum and maximum height of the point cloud (already done). Create sections every 1m, starting from the minimum height up to the maximum height. For each section, create a buffer of ±0.5m (so each section spans 1m). Finally, filter the point cloud to extract the slices based on these buffers.My idea is to extract the Bounding box of the pointcloud, extrude it 0.5m lower, and then slice it starting from bottom every 1m until reaching zmax, and use them with Clipper.How can i slice this bounding box?I thought about creating a new attribut Number of slices = zmax - zmin and then use it

I am trying to write out to a DWG from multiple inputs and need the output file name to be a combination of variables i.e.  Extract_@Value(lot_number)_@Value(survey_type)@Value(survey_number)_@Trim($(_extractCoordinateSystem),EPSG:)_@DateTimeFormat(@DateTimeNow(), %Y%m%d).dwg The variable creates fine using a variable setter   But when I try to run the writer it fails. It appears it is trying to write the file multiple time and fails to overwrite   

Hi All,I have recently upgraded from 2022 to 2024. Previously, when choosing to remove an attribute from within the AttributeManager transformer, the name of the attribute was removed from the ‘output Attribute’ column. This was very handy as it gave a good visual prompt for how the new dataset would appear. Example shown in the screenshot below:I now notice with the new version that the name is no longer removed and stays visible in the Output Attribute column. Example shown below:Does anyone know if this is this something that can be changed in a setting somewhere? I know this is only a small thing but it made a big difference to my day lol :D Thanks!
