FME Form

Hi all,I’m looking for assistance with calculating the Internal Rate of Return (IRR) in FME for a dataset containing annual cash flows grouped by a RecordID attribute.I’ve attached a sample CSV file ("Annual_cashflows_by_RecordID") that includes the data I’m working with. Each RecordID represents a unique group of annual cash flow amounts. My goal is to calculate the IRR for each RecordID.From my research, it seems the best approach is to use a PythonCaller transformer, but I’m not familiar with Python coding or how to configure this transformer for the task.If anyone has experience with similar calculations or can provide guidance on setting up the necessary transformers (or Python script), I would greatly appreciate your help!Cheers,

I have a workflow that assesses the proximity of points along lines. These points extend along a series of line segments of varying lengths. For instance, the distances to the next points might be 0ft (the start), 100ft, 100ft, 200ft, and 250ft, so I would like for the corresponding field next to these values to display 0ft, 100ft, 200ft, 400ft, and 650ft, etc. I am aware of the workflow to find cumulative sums (Attribute Creator>Statistics Calculator>Attribute Renamer). While this processes as described, I regret that the cumulative sums do not “reset” when there’s more than one batch of point data within the feature table (the initial point of an additional batch of points simply takes the prior set’s end sum and begins adding new distances from there). If there’s a way to prompt the cumulative sums to account for new “initial” points in a feature dataset and so start from scratch each time, I would greatly appreciate any insight on how to prompt that to occur. I’m happy to sha

I have a requirement to modify the list attribute generated on schema port.Lets say my schema scanner have default attributes name, fme data type and native data type.I want to look on name attribute and find any of its elements have OBJECTID string and remove if it is present.I try to modify list attributes using python caller. It modifies the list elements when I overwrite using feature.setAttribute method it is not working and returns original schema attributes unmodified. Any help using python would be highly appreciable. 

I’m trying to output all property sets from IFC files into separate Excel sheets. So far I’ve found all of the property sets, their attributes and their attribute values. This is my data:What I would like to do is transpose this list into separate lists for each property set like so: After that I could simply write each list to separate Excel sheets, but this is where I get stuck. I create the sheets by feeding the writer from a DuplicateFilter, but how do I join each PsetAttribute to Pset as well as transpose the data so each PsetAttribute is a single column?I need to do it without knowing the exact names or number of property sets existing in each IFC file as well.

Hi, I have a lot of polygons. I want to identify these ones who contain arcs.option: the polygon is made of lines onlythe polygon is made of lines and arcsI want to filter out all the polygons that contain lines only (option 1). I want to keep the ones that contain arcs (option 2). I tried the geometry property extractor but all polygons are always rejected : MISSING_GEOMETRY_PROPERTY as the error message. I don’t understand why. pls advise. 

"Failed to free sufficient memory to reach the process usage limit"This warning is appearing my log files. What do I need to do about it? What is the potential impact if nothing is done?As far as I can tell there is nothing wrong with the output files the script is creating.  

Hi,After a migration to Office365, FME is unable to open Access files. The following error is given:Microsoft Access Reader: Unable to find provider 'Microsoft.ACE.OLEDB.12.0', falling back to 'Microsoft.Jet.OLEDB.4.0'.

Host Revit file has 137 linked files.  When I try to read even a small portion of these I get the error.Failed to obtain any schemas from reader 'REVITNATIVE' from 1 datasets. This may be due to invalid datasets or format accessibility issues due to licensing, dependencies, or module loading. See logfile for more information.I’m using a FeatureReader linked to the Metadata.LinkedInformation output of the host Revit file (first strcating the LinkedFilePath and Name attributes).  I get this error even when I limit the input to one record.  Separately, a FeatureReader (along with Creator to initiate) can read one of these files. I saw a similar post where the answer was to change the FME_Temp folder.  I don’t think this will make a difference since I get the error when only trying one file.  I would try this but I need admin rights to set this up on my computer and I won’t be able to get that until next week.  Also, I would rather know for sure before I ask. Thanks in advance. 

Hello!I am new to using FME and I am working on converting an FBX file storing a 3D terrain model into a CityGML format. I have come across with two questions. How to generate a TINrelief from an FBX file in FME? Does a TINrelief have/need a GML/JSON encoding in CityGML/CityJSON for conducting further geospatial analysis? Can it be a TIN file or a Geotiff file?Thanks!

Is there a way to join two tables using the between operator (SQL). I know I can use SQLCreator but I would like to do this join directly in workbench. sql example: TABLE1.*,TABLE2.*FROM TABLE1LEFT JOIN TABLE2 ON TABLE1.NAME = TABLE2.NAME AND TABLE1.DATE BETWEEN TABLE2.FROM AND TABLE2.TO

Hello,I want to create a workbench for a datastreaming service, that will be call through fmedatastreaming.I want to test and call this service with a FME workbench including an httpcaller transformer.Il a want to pass information through an Upload Body. How this information will be pass and how to interpete this in the workbench of datastreaming? Do you have an exemple ? Thanks

I have a work process that inlcudes running FME jobs daily.I would like to automate logging of potential errors. To do so i am thinking of just reading the .log files from the workbench(es) and search for error as keyword to catch if something went wrong in the translation. I thought it would be straight forward to implement, but i cannot find a way to read .log files using FME directly. Instead I am thinking to use a python script. But I wanted to ask here if I have missed an easy method to check log files for errors.

Hi,I am using FME Workbench 2024. I am wanting to know if I can use a loop or iterative process of some sort to individually run multiple feature classes and shapefiles through a single AttributeKeeper Transformer for each data source, possibly using the names as an iterator. I am working on bringing in utility data from multiple sources and ultimately writing them to a single geodatabase feature dataset. First, I want to clean up the fields and only keep certain ones. Each source of data has a different schema. Currently, I can only use an AttributeKeeper on each feature class/shapefile in order to later output each to its own feature class in the output geodatabase. This would make for a messy workspace with many of the same transformers. Any advice would be greatly appreciated!

Hi All,I am working with lists and require some guidance on the below scenarioI have list which contains 'n' elements. I would like to add a sub-element to each element in the list.Assuming my list name called as "list{}"Example: (My list currently looks like this)    List{0}        element1        element2        element3    List{1}        element1        element2        element3    List{2}        element1        element2        element3    List{n}        element1        element2        element3        I would like to add new sub-element called "element4" at the end of each list element (i.e., add "element4" as sub-element below "element3" )        Expected Output (I would like to achieve something like below)    List{0}        element1        element2        element3        element4    List{1}        element1        element2        element3        element4    List{2}        element1        element2        element3        element4    List{n}        element1        element2        elem

Hi!I have a list, containing between 5 and 50 values (varying). How can I append a value to this list? I can only assume there has to be a non-pythonic way, but I struggle to find one. My approach was to use AttributeCreator, but I can't dynamically specify the position in the list. Had the list size been fixed, then that's a solution - but not in this case.Any ideas?

I have a database NAME1.If I open them as Oracle Non-Spatial I can access the following tablesNAME1.AANAME1.BBNAME1.CCNAME1.DDNAME1.EEIf I open them as Oracle Spatial I can access the following tablesNAME1.CCNAME1.DD The database contains more than 50 tables. They must be transferred to POSTGIS database with a different schema name: name2I have already looked up some things in the community. But those are old posts and some transformers don't even exist. What is the best way to approach this? in short:Oracle NonSpatial tables and Spatial tables from 1 database to POSTGIS database with a different schema name. Who can help me and or has an example? Thanks in advance

Before the web presentation of Safe and FME changed to what they are now It was possible to find the zipped FMEData. Data that are pointed at in almost every exercise in the FME Academy, community postings and videos.The new FME page does not provide the “knowledge” structure anymore as before and all links in the community etc. are pointing straight into Nirvana.I can see that these resource now can be found at https://s3.amazonaws.com/FMEData, however, I cannot get a listing of the content of this bucket and I always end up with a 403. Without a listing it is impossible to guess the specific file I am interested in…Can somebody point me to an URL where I can get the latest version of the FMEData?

i have daily & repeated work in geospatial data and I did it manually it takes a lot of time 

The IFC data was exported using ArcGIS Pro. After importing it into FME Data Inspector, the following errors occurred:ISO10303-21: Skipping instance #50: Instance  is not syntactically valid An error has occurred. Check the logfile above for details Failed to specify the feature index as constraints on the reader  Could anyone please help with this? Thank you!

When trying to read an IFC file, I am getting an error ISO10303-21: Skipping instance #1154: Instance is not syntactically valid. How can this be fixed?

Hello! I’m trying to use the Cartegraph Connector and could use a hand. In the past year or so, I believe the API URLs have been updated compared to when this custom transformer was originally made. Now, I am having trouble with the very first step which is authenticating. I think I’m using the wrong URL to have my username and password accepted by the API. Also, this custom transformer was created in 2022 and may not work any longer for various reasons due to versions.As a test, using Postman, I have tested some API URLs and can successfully connect and perform a GET command and get back data. This shows that I’m close.. something works in Postman - so we’re on the right track.. now to get FME to connect.Because this is a work matter, I cannot share a great deal of information openly here. If anybody has a clue about getting connected to Cartegraph as it’s configured today (2024/2025) that would be awesome. Thanks and take careJim 

I’m at working on matching indoor point cloud data to gml LOD2 data using ICP so I want to transform my gml data to a point cloud data to help ease the matching. Can anyone please help me? question is how do I transform GML LOD2 to point cloud data? also if there are other suggestions to complete this task. Thank you 

I need to copy records from one hosted feature layer in ArcGIS Online to another hosted feature layer. Schemas are identical. Some of the records in the source data have an attachment (only 1 per feature/record so only in the 0 position in the list). No problem getting all of the records to write from the source to the destination but the attachments are not included. Anyone know how to do bring over the attachments with the rest of the data?

Hi,I have some villages (Primary and secondary villages), each containing a main folder, a subfolder, a data folder, and some empty folders. I will designate one village as the primary village. All sub-village files/data will be stored in the main village folder. Only location path links will be kept in the secondary village folder (marked in red color). Other data will be sourced from different locations (Marked in green color). Finally, I must validate whether all folders and data have been correctly segregated or not. I am currently performing this process manually, which involves copying, pasting, and validating each folder and village individually. This manual process is quite time-consuming and manpower. Kindly help me about this test cases and workflow. I am new to FME and am eager to learn more about its functionalities. Thanks.

Though experienced with reading WFS's, I'm a little bit frustrated about reading a WFS2.0 in the FeatureReader. It seems it is not paginating. Checking the WFS GetCapabilities, 'FeaturePaging’ is not mentioned.I want to query the WFS with a polygon. So that is my initiator. But I'm not sure whether the results exceeding the 50k or 100k or even 200k. That's why I want some sort of ‘FeaturePaging’. Anyone an idea on how to solve my issue? It's probably simple, but I can't see it at the moment.
