Qgis in FME calling pythoncaller

Hey, I’ve been trying to get FME (Feature Manipulation Engine) by Safe Software to use Python libraries from QGIS (like qgis.core) so I can mix their cool features in my temp.fmw workspace. The idea is to use QGIS’s Python (version 3.9) inside FME by setting it up with PowerShell commands. But it’s not working, and here’s why, explained like I’m talking to a 5-year-old and then a bit more grown-up: The Toy Box Story (Simple Version) Imagine Python is a kid who needs toy helpers to do jobs—like QGIS toys (for maps) and FME toys (for data tricks). These toys are called DLLs (little helper files). I want Python to borrow toys from both QGIS’s toy box and FME’s toy box at the same time. Step 1: I told Python, “Look in QGIS’s box (C:\Program Files\QGIS 3.32.0\apps\Python39) and FME’s box (C:\Program Files\FME\python)!” That’s like setting PYTHONHOME and PYTHONPATH.Step 2: Python found some QGIS toys (like qgis.core), but then it yelled, “Where’s my Qt5Core.dll toy? I can’t play!” It’s like

Reading and IFC-file, reproject it and write back to new IFC-file

I am reading an IFC-file using a FeatureReader with the following configurations: I am using the <Generic> port to connect it to a Reprojector-transformer. After reprojecting it, I want to use a FeatureWriter and write it as a new IFC-file. I am however stuck on how I should set up the FeatureWriter. I have managed to get a new IFC-file, but the file size is quite small. I am interested in automating the process, and want the FeatureReader to accept any types of IFC-files. Any tips on how I can solve this?

Raster Calculator not calculating all files that were input

In my workbench I am taking points, buffering them, and using those buffered areas to clip small portions of a raster mosaic. After clipping I then run a raster calculator on each of those points to find the sum, mean, min, max range, etc and create an excel file with all the values calculated and collected. My workbench runs successfully, however in several of my datapoints I get empty rows with no stats being calculated. When I check the area in ArcGIS Pro there aren’t any null values in those areas and it runs without any issue. I have tried using RasterBandCoercer to change any null values to 0, rasterbandnodataremover, and nullattribute mapper to help deal with these issues but none of them give me results that I can actually use without skewing the data and giving me invalid results. Does anyone have any suggestions or ideas on how I can fix this issue? Currently running FME(R) 2024.0.1.0 Thanks!

Detecting the Geometry of a Feature Class in a FeatureWriter (ArcSDE Geodb)

Dear FME Users, In our organization, we frequently work with Esri Geodatabases, and we often use FeatureWriters to write data to these databases. This process has always worked smoothly for us until we updated our FME Form to version 2024.2. Since the update, we've encountered an issue where the geometry of a feature class is no longer auto-detected when adding a connection to a .sde file (we always embed these connections) and then adding a feature class from the dataset. Previously, this functionality worked perfectly, and we appreciated not having to manually set the geometry. Could this issue be related to the version of FME Form, the transformer itself, or are we possibly missing a setting in the FeatureWriter setup? Example Interestingly, when we select a table without geometry, it is auto-detected as a 'geodb_table'. However, for some reason, geometries are not being detected. Any help would be appreciated!

Create a 3D polygon and flat from dimensions

Given the height, length and width of an underground vault, I'd like to create a 3D box of the vault. I'd also like to create a flattened box out of the same dimensions. I've started out with a creator, cloner and a 2dBox replacer then a 3D extruder for the box. I'm a bit lost with the flattening of the box in a 2d plane. Any suggestions on how to get the bottom corners of boxes 1,2,3, & 4 align with the corners of box 5? The bigger challenge is how to project this so I can draw this in a DWG file later in my translation. I have a lat/long as the center of each vault and I could probably start at zed value of 0 initially. me dimensions.

MapInfo transformation not reading right Coordinate System

Hello FME Folks,This is related to MapInfo Tab files. Since we upgraded from FME 2018 to FME 2024.2.1. The MapInfo coordinate System (Non Earth Meters) are not detected which used to happen in FME 2018. Instead it is taking wkt_auto_1 and is misaligned. Please let me know what changed.

LengthToPoint transformer - multiple rejected ports

Upgrading 2023 workspace to 2024.2. When upgrading or adding a new LenghtToPointCalculator transformer and referencing existing attributes for the X/Y coordinates, FME adds 2 rejected ports to the transformer. If you then run the workspace you get the error: Cannot have multiple factories with the same name. Multiple factories were assigned the name 'LengthToPointCalculator_<Rejected>' Any suggestions on how to get only 1 rejected port? Thanks.

Custom transformer Community Publisher name not showing

Hi everyone, I've just uploaded my very first custom transformer to the FME hub which I'm very excited about. However when downloading the transformer it doesn't show my name next to the community publisher. Any idea how to show my name there? A lot of time went in this transformer so a little bit of credits would be nice :)

MULTI_WRITER was not specified error: Why do I need it? How do I resolve?

I'd like to understand what this error means in the following context and how I might go about resolving it. I have a workspace that works perfectly fine if I run using cached features up to transformers just prior to a FeatureMerger then run from the FeatureMerger to a writer. However, when I try to run the entire workspace it results in an error that aborts the translation at the writer. I've also tried many other methods of joining these 2 streams and all are resulting in the same error output. MULTI_WRITER: No MULTI_WRITER_TYPE{*} or MULTI_WRITER_TYPE{3} was specified It seems like I need both streams to be ready at the FeatureMerger at the same time but I have not been able to gain control over execution order or block passthrough features through a variety of attempts. The goal is to read from both a CAD model and a DB, then compare the two datasets on a unique key, then write an SQL statement to a text file or SQLExecutor. I've only attempted this with the text file writer while

How to iterate though a list of strings read from an Excel doc and attribute filters

I have a workbench that creates a table based on a number of joins that are on occasion, filtered on an attribute. Instead of manually entering the attribute values, I’d to read a list of attributes from, say, an Excel doc e.g. NSG001, NSO001, TES001 so I don’t have lots of duplicated transformers. How do I iterate through a list of values and plug them into FeatureJoiners without duplicating lots of stuff.

Multiple conditions for conditional user parameter

Is there any option how to set multiple condition for visibility of user parameter? I need some parameters to be available for two choices of another parameter. I could define another connection parameter but i have to use it in same readers and writers of workspace. - is there a chance for some workaround?I can’t merge these two choices, because there another flow for each one of these two.I know thers new feature in FME 2025, but we recently upgraded to last major 2024 version. Probably we’ll be waiting for another release of 2025.

Elevation gain along a line

I’m working on an analysis to determine the correct calculation for elevation gain and loss along a line representing a real-world route (such as a trekking, marathon, or MTB course). I’m using FME and have two source vector datasets: a GPX file that already contains Z values for each vertex and a PostGIS line to which I need to assign elevations from a DTM (Draper). Is there a standard workflow for this type of calculation?

Update/Insert specifical attribute

Hi, I have one table that have attributes called months of the year, that begin in OUT_24, NOV_24...until SET_25. My workspace will run month by month by workspace runner. In my workspace sometimes the value is filled in OUT_24, in the next execution NOV_24...until the end. How my table can be updated if OUT_24 have a values only for example? I would like to ignore attributes with missing values. I try this code in SQLExecutor: UPDATE ARCGIS.BTA_SAT_NDVI_pl SET MAR_25 = @Value(MAR_03) WHERE COD = @Value(COD) AND NEW_ID = @Value(NEW_ID); But don’t work for me...because I need to change SQL after SET to attribute with value.

Scripted Parameters to read JSON file

Hi, Is there a way to read the JSON file. JSON file consists of user parameters. I created scripted parameters for the all the user parameters but the scripted parameters are not able to read the values of the user parameters in the JSON file. Scripted parameters contain python that reads up the json file and fetches the parameter for that specific parameter. Is there any solution to read the user parameters in the JSON file? User parameters in the JSON file are dynamic.

Value as Attribute Name

Hi, I am working with FME Desktop, and at a certain point, my features have a "Month" field with values such as 10, which refers to October, 11 meaning November, and so on for all months of the year. The table that will receive this value has columns ranging from OCTOBER to SEPTEMBER. How can I make FME understand that if the column has a "Month" value of 10, the "Average" field should be renamed to OCTOBER, ensuring that the values from the recently renamed OCTOBER field are recorded in the table, which also has a column named OCTOBER? Thank´s

Ultimately the Warning has no impact on the workbench or translation, the data is definitely LL-WGS84 and a CoordinateSystemExtractor will confirm this but best practice for me

Detecting Digitization Direction Conflicts in Consecutive Lines

Hi everyone, I have a set of consecutive lines, and I need to detect when there is a digitization direction conflict between them. As shown in the image below, the green arrows represent the direction of my lines, but Line 2 is oriented differently compared to the others. Is there a way in FME to detect such conflicts? Ideally, I’d like to flag or filter out the lines that have a reversed direction compared to their neighbors.

Run multiple FMW files after each other

I’ve read a couple of posts on this, but I’m still not perfectly sure on how this works. I have over almost a year been working on and refining a flow. Since I keep getting new updates from the project, the flows has became large. It became into 3 flows, that could maybe have become 1, but I don’t think it would be that easy, at least I’m not up for that task. It consist of multiple feature readers and multiple feature writers. Each flow takes up some data from the other. For example something can have been made in a file Geodatabase or on ArcGIS Online, and the next flow would then use that content. So, I easily enough just want to run those 3 flows, by one click in workbench. I would expect just to create something like this. I just find it’s strange to connect it like that. Is it that easy?
