Transformers

Hello,I have a set of pairs of points that each have a uniqueID_start and unique_end field. I am trying to extract all of the line segments between each pair of points. The tricky thing is that the pairs can be several line segments long, and have other pairs intersecting them:There could also be several points on a single spot, but corresponding to different pair sets.It’s a mess! Any help would be wonderful!

Hello, I have a reader with a shapefile that has contour lines in it. I have connected that to the ContourLabeller transformer. I have taken the label output port of the ContourLabeller and run it to a DGN Styler where I have styled it. These parts are all working but when I write it using the DGN (V8) writer the label level is not created. What am I missing here? Thanks!

Hi there,I have severale profiles, which fly somewhere in 3D space.The elevation always follows the z axis. The direction varies, but follows one direction in XY level.I started like this:BoundsExtractor get the bounds (aka rotation axis) GeometryRefiner do some geometry refining 3DRotator rotate around the axisResult:3D view

I’m trying to make a KML from a CSV with Geometry in WKT. I have got up to the Extract Geomery transformer but keep getting the INVALID_GEOMETRY_VERTICES error.

Hello, I was just wondering if anyone has successfully used the AutoCAD Dimension attributes to validate angles?I have a example drawing below where the angle of the lines is added as text in AutoCAD using the DIMANGULAR function in AutoCAD. When FME reads in the features, using ‘Explode Dimensions’ set to No, I get a series of attributes against the text point with the coordinates of lines used to determine the angle in AutoCAD. What I have found is that defpt2 to deft4 aren’t always in the order to create lines and test the angle between them and was wondering if anyone else has had success in validating angles from a DWG?

I’ve been successfully utilising the Microsoft Email Service via the Emailer transformer for sometime - I noticed last week that all emails scheduled to run via FME flow stopped working, and when I opened the workspaces to reauthorise Microsoft, I was met with the following error: “Unable to retrieve access tokenRequest to update access token failed. HTTP Error: HTTP/1.1 401 Unauthorized” My IT department can see on their end that the logins have been successful via FME Emailer Enterprise Application on Azure.  

I have many SQLExecutor transformers and for any reason they use to lost the geometries.The visual preview nor the data inspector show any geometry, only a “There is no geometry in this view” message.When they should save the results in the next FeatureWriter (in a postgis database) only the alphanumeric fields are correctly writed, but the geom field is fill with nulls.When I execute the same sql sentence in QGis or pgAdmin I get the geom field with the correct geometries.I'm not be able to find the fix for this issue. Any idea will be appreciated. Thanks in advance.

Hi,I have an FMW (FME Form v.2023.2) with 4 datasets, and I would like to save the results as ArcGIS Portal writers. Each dataset could change due to modifications in the underlying databases or files used in the FMW. These changes may involve the deletion or insertion of rows, updates to attribute values, or, in some cases, no changes at all.I would like to run the FMW once a month without modifying the parameters for ArcGIS Portal.How should I configure ArcGIS Portal to capture all changes for these 4 datasets?When I used Insert for Feature Option and Truncate for Feature Type Handling 3 datasets where correct updated, the 4th dataset “Alle_Adr_Adkom” got:ArcGIS Portal Feature Service Writer: 0 features successfully written to 'Alle_Adr_Adkom', but the server rejected the 48751 features in the last request due to er

Hello. I am running workspaces using FME Python API and the class FMEWorkspaceRunner, where I am currently using the method runWithParameters.I would like to know how can I change the Log file name (and path) when running the workspace in this way. I saw in the documentation that runWithParametersAndDirectives have an example about change the log name, but it is not clear for me.Thanks.

Hello,I was told that I can use HTTPCaller to automate some ArcGIS Online Admin workflows, such as creating/deleting user accounts.I found this ArcGIS REST APIs authentication document to guide me, but I can’t figure out how exactly. https://developers.arcgis.com/rest/users-groups-and-items/authentication/  Any help is appreciated! Nicole

I have a block sitting on a line and a block associated with a point in a DWG file. How can I save the label positions, including the rotation and alignment of attributes like 'ID', 'Slope', and 'IL_Out', using the CAD Feature Writer in FME?

I'm using FME Workbench version 2023.2.3. I have 2 datasets, 1 dataset contains around 2,5 million polygons, the other dataset is 1 polygon (a province in this case). I want to know which polygons overlap with the province (even if the overlap is small). I use a SpatialFilter for this, with the 2,5 million polygons as candidate and the 1 polygon of the province as filter. Below are the settings: Now I noticed some issues, where some polygons who do have an overlap, still end up in the ‘failed’ port. Like the example below:I asked some colleagues and they don't know what's going on here. Everything looks alright and we have no idea why this doesn't go in the ‘passed’ port. It

I am using FeatureJoiner to combine polygons from different source data layer. They all work fine and get combined apart from the data coming from the MapServer reader, this one gets rejected in the FeatureJoiner and gives this information:I see that data has an extra attribute: ‘arcgisonline_type: arcgisonline_polygon’, and the others from other data sources don’t have that. I am using a CsmapReprojector and converting from SPHERICAL_MERCATOR to MGA94-55 (written as “_MGA94-55_0” for all other data, and as “MGA94-55” for the data that passes through the Reprojector, the one that is being rejected, I don’t understand why they get different naming).Any suggestion if I am doing something wrong and how can I have the data not rejected please?

Not really a question, but feel free to add comments or thoughts below.We are implementing pre-commit hooks and centralized Python linters in our git workflows, and for this we need to extract all Python code from workspace files pushed to git. Since we do not want to require a full FME installation for this, we’re parsing the .fmw files as text files using Python and extracting all the code blocks within, before passing them on to the linter as if they were stand-alone Python scripts.As code blocks are encoded in a somewhat non-standard way, I’m sharing a Python function to convert FME encoded strings to regular text, without resorting to any dependencies like an FME installation, (which would allow using FMESession.decodeFromFMEParsableText) or other

Hi there,last time, this community forum was so helpful and I hope someone can help me this time around too…I’m using the Clipper to clip polygons using the Group Processing feature. Only if the values of the attribute “att_1” are the same should the clipping occur. So far so good. However, it can be that att_1 is NULL (empty) and in this case, I would like to do Group Processing using attribute “att_2”. Is there a way to configure this in the Clipper directly?With my humble knowlegde of FME, I would filter for att_1 being NULL and have two Clippers (one for Group Processing att_1 and one for Group Processing att_2) and then merge the two data streams again. But is there a more elegant way?

Hi, This is defeating me!Any pointers sincerely appreciated.See attached spreadsheet, Where I have features with attributes having multiple similar IDs as well as a name attribute.I have added the columns _num and _page, that is the desired output I manually added in.I can achieve the _num output easy enough with a counter set to Local and group by the two Attributes Name and ID. I set the Count to be _num and Group ID to be _page. This works fine until the Name group changes and the _page will continue counting, See screenshot. However, when the new Name starts with B I want the _page to restart at 1. How do I set it? Thanks. Nic  

I am a Chinese student who uses FME software to read shp files and create 3Dtiers files. There is a problem loading and displaying now. As shown in the video, there is an issue with zooming in and out.Others' 3dtiles were generated using other software and did not encounter this issue. I'm having problems using FME now, how can I solve this. Please help me. My English is not very good. Can you understand what I translated using translation software.I searched for some 3dtiles files and someone said it was a geometricError parameter setting issue.Where can i set the 3dtiles geometricError ???please help me .I am bad in English.my Emial 1985425275@qq.com 

Hi there, I am trying to extract links from this page Mornington Peninsula Planning Scheme - Maps using the methods posted on this forum as well as from the official documentation HTMLExtractor (safe.com), however there is zero total features read, meaning no output. Would this be due to the way the site is structured? I am specifally trying to extract the urls for the PDF maps on the left, and output to a SQL table and link to our GIS, as these links change every so often.Regards,Josh 

Hello, Am I the only one who is experiencing lately that if I have several models open and I do a purge tempory files in 1 of them then it then does the same in the others? The numbers remain in the other model but the green box to view is gone and I have to run the whole model again :-(I do that because sometimes I update a reader but then it won't run again without me doing that purge.  

Hello everyone,I am currently making a script that looks for houses that have a garden. In my current script I have two datasets: 1) houses, 2) gardensI used for now the NeighborFinder transformer and I have a maximum distance of zero, since the gardens and the houses need to touch one another. So far, so good. However, now I get another problem.I have the following situation. You can see in the drawn example below that the garden and House 1 share a line, while this is not the case for House 2. However, based on my current settings in the NeighbourFinder, the garden is as well considered a neighbour for House2.How can I go about it, that House 2 is not included, since House 2 and the garden don't share a line, but only one vertex. Do I need to change  some settings in the NeighbourFinder or do I have to go differently about it. 

I need to dissolve line segments into long line base on some attributes. I tried LineCombiner and it doesn't work, still same segments in the result.

Is there an option or setting that I have missed?I have a reader pulling in data from a portal feature service. I set it to resolve domains.I have a field that, for whatever reason, the coded value is not being resolved so the “_resolved” field is being populated as <null>.Rather than having to add transformers to each of my workbenches to check each of my domain fields, I was wondering if there is a setting I am missing somewhere?In this instance, I would rather have the coded values populate the “_resolved” field rather than it show up as “<null>”. Is there an option that I can set in the reader (or somewhere else) to be able to do this? I am using Workbench 2023.1. This post indicates that there was no option 3 years ago… hoping there’s been an update made?

Has anyone experienced a workbench erroring when feature caching is disabled? For context I have had this workbench running through task scheduler for around two years (keeping it updated) and recently discovered an issue where it crashed at a specific transformer (feature joiner).In testing I have run the workbench with feature caching on (it worked fine) so I tested all the normal points - replace transformers, replace readers/writers, change user credentials. When I turned off feature caching is where the error occurs (in the same spot as when running it through task scheduler).The attached logs show where it crashed on the feature joiner, has anyone experienced this? My last step is to recreate the workbench from scratch and test that as well.

Hello, I am attempting to replicate the following PostGIS SQL code within an FME workspace: where ST_DWithin(property_boundary.shape ,restriction_area."SP_GEOMETRY",100) and ST_AREA( ST_INTERSECTION(property_boundary.shape ,restriction_area."SP_GEOMETRY"))/ST_AREA(restriction_area."SP_GEOMETRY") < 0.1 property_boundary layer is parcel data for an area. restriction_area is a collection of polygons where the same restriction applies but for different reasons which is listed in the attributes. If the above script is true for a given property an attribute is then applied. I am not very familar with PostGIS SQL, but from my understanding, this script is filtering for all property_boundary shapes that intersect a 100 meter buffer of the restriction_area. Then, it calculates the total overlap between each property_boundary sh

Hi,In my workbench I’m trying to export points and labels from Oracle database to Geopackage file.So I’ve configured an Oracle Spatial Object Reader and a TextAdder. On the TextAdder’s output I can see points with labels. Then I’m adding a writer of type OGC Geopackage.But when I’m trying to run process, the result GPKG file contains only points (without labels).On logs there’s a information: “Unsupported geometry type Text.  Downconverting to Point”If I replace OGC Geopackage writer with Bentley Microstation Desing (V8), then it works properly (I mean the result contains points and labels).How to export labels to Geopackage?
