Transformers

As mentioned in another post, I'm currently upgrading a bunch of workbenches to run on FME Flow 2024, some of them many years old. Typically, for anupgrade, I will go through each workbench, upgrade all transformers, readers, and writers, then run it in test desktop (workbench) environment, then publish to and test in a test server (flow) environment.In, FME 2024 the Vertex Extractor gives me bogus results, even after upgrading all the constituent transformers in this custom transformer. It looks like X and Y, or Lat and Lon, are reversed.When I open the CoordinateConcatenator (arrow above), I see this:

I hope I got the title prepositions correct…I want to break apart lake data in order to generalize each category individually. The DonutHoleExtractor will “only” break apart “one level”. That is, independent-lakes and island-in-lakes-on-islands get sent one way and islands-in-independent-lakes and lakes-on-independent-islands get sent the other. Last option is to use an AreaOnAreaOverlayer or similar to sort everything correctly. But I would rather save that computing time since this is a huge dataset. Unfortunately the DonutHoleExtractor does not have an option for lists, or that would have been my chosen route, me thinks. Once generalized the geometries will be reassembled into donuts.  Q: Is there a way to deduct the relations between different types of polygons within the donuts without doing a load of spatial analysis? I would expect there to be some sort of relation info within the geometry type itself?edit: Rephrased the question for clarity  

Hi Team,I was wondering if there was an ETA as to when a permanent solution for fixing FME Form (and Flow) will be available, as we're still experiencing issues with reprojecting data in GDA 2020. The work around at the moment that we have been given is;- Open up the following file in Notepad (open as administrator) :"C:\Program Files\FME\Reproject\CsmapTransformationExceptions\TransformationExceptions.db" - Find the Australia section and add the following line : GDA2020-7P|GDA2020|XFORM|FWD|NULL_FME - Save!Cheers 

Hi FME world,I have two tables in a database (ArcGIS SDE). They are effectively a 1:1 match, linked via a common ID. Table 1 features are always present in the flow (filtered prior) and I want to read in ONLY the features from table 2, where match with the Table 1 filtered features (because there are 1m+).I’ve tried options like aggregating the Table 1 features and concatenating the ID, passing into Table 2 feature reader with a where clause. However, there is a maximum limit of queries the database can do (somewhere between 10,000-15,000 - and often I will need to read in more than this.My next thought is to create a looping transformer where I sample the T1 features into groups of 10k, aggregate, pass to FeatureReader, reads in associated 10k T2 features, then loop back to read in the next 10k, until there are no more features to be read (using a NoFeaturesTester to exit the loop.I’m a bit stuck on how to actually implement this though. Any ideas/though

Hey,  I have a question about the HTTP Caller. Is there a way to have the workspace it is in still continue even if one of the records fails to upload? The reason I ask is because there are some interesting errors I have ran into when uploading records to Cityworks, where something fails and then I have to re-run the entire workspace, after first deleting all of the inspections/work orders that were created.  The error involves an encoded string not being compatible with FME. I would just like a way to run the entire workspace for all features and not have it cancel out on a failure. Any tips?

With the CKANConnector able to list Datasets and Resources without any issue, so I know CKAN Connection is good.   If I try to add and update a resource I receive the  “upload error HTTP 400: "Bad request - JSON Error: Invalid request. Please use POST method for your request”    I’m pulling the Dataset and Resource for the update resource from the dropdown.    Acts like a permission issue but I’m connecting as an Admin  on the openGov side. 

Huge thanks to ​@mark2atsafe for granting me a shiny FME Star badge!It really gave me the push to finally share some of the custom tools I’ve built, starting with this one: the TimeSeriesGenerator. The idea came up when I needed to build a time‑series dataset to plot user activity over time. My end goal was to generate an HTML report showing how users interacted with an application. I was starting from a log file of user requests, but if no one made a request during a given period, I’d

I'm working with an electrical network with feeders and branches. I'd like to add the coordinates of the intersection points with the feeders as attributes in the branches. I managed to do this in the first segment using the Intersector and SpatialFilter transformers, but I had trouble adding them to the downstream segments.I have a common field for each branch that can be obtained using networkTopology.So, my question is how to create conditional queries to add the coordinate values ​​of the intersection points with the downstream branches (see attached diagram).Thanks in advance. 

Hi, I'm trying to access the property sets within the Extended data from dwg file, the property sets are attached to block reference objects, quite similar to the case of this post.Attached below are two snapshots from how the property sets look like in Autocad and FME workbench featuring the two attributes that I was trying to expose with no successcan someone guide me through the detailed workflow, please? I'm using FME workbench 2024.2 Thanks,

Hi everyone, quick question: how can I remove the rows from my Excel file where the ID number is duplicated, so that only one record per ID is kept?

HelloI am trying to figure out if it is possible to read Levels from a .dgn files, and rename them according to a Table given to the script. I work at a public contracting authority where we receive “As-Built” .dgn documentation from our consultants, structured according to industry standards regarding level naming, and it would be a huge help if we could rename them to a human readable name which our maintenance employees can understand.I guess I’ve found a way to “read” levels in Microstation files, but I cannot seem to find something that can write Levels. Is that possible with FME? Any help would be appreciated. CheersIoannis

Dear FME Community,I need to calculate measure PK from an object, modify them and apply to another object for cut it to elements.I try to explain all steps with this schema :I’m at the STEP 4 but I’m blocked when I want to apply my Measure PK to another objet.For that I’ve a FMWT in ZIP join to this subject.Thank you for your attention and your help.Geo-x

I am hoping to produce a group of points along polylines of various lengths. I’ve been trying to mimic the GeneratePointsAlongLines() method from arcpy and ArcGIS Pro which will simply build out points from the start of a polyline at a designated interval (regardless of line segment vertices). I’ve investigated Densifier, but this transformer incorporates vertices and produces points that do not conform to the designated interval. I’ve contemplated utilizing Snipper, but this seems challenging given that many of the line segments I expect to incorporate may vary in lengths for different inputs.I’d appreciate any insight that can be offered.

Hi. I'm reading dwg files with the civil 3D reader. I need to use the attributes in the propertysets. this works perfectly with exposing 'autocad_xrecord_datalist' in the reader for all geometry types, but not for the blocks. the property set attributes from the block don't seem to be present on the 'autocad_insert'. I tried exposing fme_attrib_info but they are also not there. any ideas? or is this just not possible on blocks ?i added a screenshot of the pset in the dwg

Hi,Does anyone know how to retrieve the information from the Settings tab of a layer published to Esri ArcGIS Online (AGOL)? I’m specifically trying to get the Data Source URL. The Request URL I’m using doesn’t return that information. Any ideas? 

Sometimes when I do a transformation from dwg to shape everything is included in 1 polyline (text, pipes, arrows) and when I look at it in inspektion mode I see that the dwg is splitting the lines by color, how do i do the transformation with a separation by color or adding the color value inside the whole polyline Sorry if my vocabulary is wrong

Hello,This should be a very simple thing, but I just can't figure out how to do it!I want to append two tables together (Tables 1 & 2), both with very similar attributes, but I want to use the ID from Table 1 as the official Primary Key, and then get the highest number from that PK and increment upwards to create new PK values for the Table 2 appended values. I can get the maximum value from Table 1 using StatisticsCalculator, but I can't for the life of me work out how to use that value in the creation of the new Primary Key.I've been trying to do a conditional value calculation in Attribute Manager, something like, if Table 1 ID has a value, then PK = Table 1 ID, else use MaxValue from StatisticsCalculator and sum it with @sum(@double(@Count()),1.0) to increment up. But it's not working.Any ideas greatly appreciated!Thank you!Katrina

I am Featurejoining the output from a change detector that compares an original layer from ArcGIS Online to a revised layer from my Geodatabase.    Note:  The AGOL layer was originally published from ArcGIS Pro from the coordinate system WGS 1984 Web Mercator (auxiliary sphere) .The Featurejoiner transformer rejects the features saying: “Coordinate system does not match first feature's coordinate system”Similar to the issue as seen in https://community.safe.com/topic/show?tid=20659&fid=8When I inspect the original and revised features, my features on AGOL have “SPHERICAL_MERCATOR” and my revised features have “SPHERICAL_MERCATOR_0”In  my workspace, my revised features are reprojected with ESRIReporojector to WGS_1984_Web_Mercator_Auxiliary_Sphere before entering the change detector. They then show a Coord

I have a JSON file from waze that I am trying to read.I am using the JSON (JavaScript Object Notation) reader.There are three schema; alerts, irregularities and jamsI can read alerts okay with this queryjson["alerts"][*]Flatten Nested JSON values into Attributes = YesRead Entire Feature as JSON Fragment = Nowhich reads 433 alerts, each with a location.x and location.y which allows me to built a point object (Vertex) for each feature.But I am struggling with the irregularities and jams.The irregularities have a line object which obviously does not convert into two neat columns.How do I read the line object?I have attached the json file here

Hi All,I have set up my tool tip to tell me the version number of a particular Transformer in my workbench.Is there a way of relating the version number of a Transformer to the version number of my software?Can I find out which version of the software that a particular Transformer has an upgrade?For any particular software version, is there a list of the version numbers of the Transformers?Thanks,Nick

Hi everyone, I have a question: how can I use FME to create a series of equally spaced points along a 3D polyline provided as input from a DXF file?

I don’t have an programming background, so please bear with me. I need to find out the circular standard deviation of the rotation attributes from a set of features in degrees.The built in AI in the PythonCaller has taken me as far as the code below. I have tried many different prompts, they use somewhat different methods to do the calculations, but all throw errors about missing methods or incorrect classes. It seems that the AI is unable to initialize the script “The FME way”, or I have not figured out the correct prompt.What do I need to ad to the script in order to get the below working? My desired output is the circular_standard_deviation as a new attribute.Another nooby question, what should I write in the box: Class to process features? import mathimport numpy as np# Function to calculate circular standard deviationdef circular_standard_deviation(angles_deg): angles_rad = np.deg2rad(angles_deg)

Have a DTM. Am creating contour lines. Are there any tools in FME that can be used to identify any Depression Contours in the data?

Hello, so we have now switched from Server to Flow and all is good and great except from one bit, and that is there have been made some changes between these versions that have made my emailer workarounds from Server useless.So what we did before is that we just set up the Emailer in the workspaces and sent automatic answers in the ‘Body’ section of the Emailer such as:p>Hello Colleague</p><p>Here is your GeoJson to DWG/Shapefile datapackage:<a href="$(FME_SERVER_DEST_DIR)">Click me to download</a></p>Where the ‘$(FME_SERVER_DEST_DIR)’ was the download link for the result and it worked very well.But now on Flow it doesnt work, the email sends and all but there is no value being fed into the ‘a href’ so now download hyperlink for the message.What has changed here, is it only the value for the URL and if so what value should I be referring to now to get the result data on flow downlo

Hi All,How can I add a conditional parameter (visibility) in FME 2022? I know it’s possible for 2023 but can’t find it for 2022.I have created a workflow that allows the user to export data into different formats (E57, CAD, LAS, XYZ) and I want to offer the option to export the data as DWG or DXF if the user picks CAD, some images below: ...then the user only has the ‘Choose the output CAD format’ enable if CAD was chosen in the first parameter. I’m on FME(R) 2022.2.5.0 (20230329 - Build 22795 - WIN64)
