FME Form

I would like to convert surface data (like mesh or LandXML) to IFC (using for example the ifcTriangulatedFaceSet class). I think, it has to be quite easy but I have no idea how to write those IFC data.I attache an input example-file (LandXML).Thank you very much for any suggestions.Franco

FME Desktop 2022.2Objective: I want to terminate my workbench if the FeatureJoiner spits out any UnjoinedRight records. So this means, even if there are any Joined records, I want these to also terminate in the flow because there are UnjoinedRight records being caught.  Workflow and Logic:I have the following set up but it is not working. Notice in the screenshot below, I added a counter to the UnjoinedRight port, and a Tester. If the Tester conditions are met, they Pass and I want the Joined record to move along. If the Tester conditions are not met, then they Fail and I don’t want the Joined records to continue and would like the workbench to Terminate. 

Hello,I have a workbench 2022.2 that writes out data from a join of another feature service to an SDE feature class out to an existing service. I am using an attribute manager, see below, before a date formatter and reprojector. However, when I run the workbench, the writer always gives me a mismatch on attribute sizes error in manual and automatic modes. I have tried to update the attributes to the values listed in the error but it always seems to revert back. I know I am missing something simple but for the life of me I cannot see what.Thank you for your time. Scott

Hi,How can I calculate NDVIRe, using RasterExpressionEvaluator? NDVIRe=Band 8 (NIR)+Band 5 (Red Edge 1) / Band 8 (NIR)−Band 5 (Red Edge 1)​I don´t know to configure the transformer properly… Thank´s 

Hi!Is it possible to backup a PostgreSQL database (or a specific table) using FME?

Hi everyone,I have an SHP file related to some parcels. For each parcel, there is a corresponding folder and contract (with the same name). My goal is to create a workspace based on the ready SHP files (using a simple tester transformation). The SharePointOnlineConnector should then download the corresponding contract from SharePoint and place it in a local directory.My main challenge lies in how to locate each contract. Currently, I’ve set up the SharePointOnlineConnector to create a list from the directory. Then, I use another SharePointOnlineConnector to download the contracts. However, during the second SharePoint transformation, I encounter an error:SharepointOnlineConnector: Error making request to https://graph.microsoft.com/v1.0//sites/[my_share_point_name].sharepoint.com,3a2333c0-9794-425a-9978-a2eb613fc15b,c38a05da-86b2-48bd-a5b5-e80371d96e57/drives/b!nqLU0gc2Y0OJ_TIlc0aqVX_zKy7OiIFPltGPSW8STP_RoqJOec4

I have a number of CustomTransformers which contain some python - this python may or may not include some third parts python dependencies. It’s not only python, they also use regular old FME transformers as well.I’ve been playing around with the package development guide and doing some testing. I can see how to import third party modules for just normal CustomTransformers. I’d really like to be able to use the package manager tools here to help with dependencies, however, it seems like from my experimenting that fme based custom transformers can not benefit from these tools.Does any one know anything or have any comments on this?

Hi,  I have one SCL band from sentinel II and would like to convert in polygon pixels with value 3 and 9. How can I do this using FME? Thank´s

Hi,I want to clip a point cloud with a 3D Object (Box). The 3D Object has z values and should overlap the point clouds. Now when I am using the Clipper, I recognize, that the point cloud is not overlapping the 3D box, because it is not using the z values. How can I proceed in this case, that both have the same elevation and that the clipping is working?Point Cloud on the correct elevation of 280m. 3D Object at the ground (not using its z-CoordinatesThanks in advance

I have address data in CSV format. there are address number ranges, street address from number and street address to number, and sequence code (1 for odd, 2 for even, and 3 for consecutive).I need to expand these ranges into individual addresses based on sequence code and write them in a new CSV.Any guidance for doing this task in FME would be appreciated. Thanks

Hi everyone,I'm working on a project where I need to process multiple IFC files and write the data to a PostgreSQL database using an FME workbench. I've written a Python script to automate this process, which includes getting IFC input from the user and executing the FME workbench. However, I'm encountering problems when passing multiple IFC files to the FME command line.Any ideas? Main Idea:Getting IFC Input from User: The script prompts the user to enter the path to a directory or a single IFC file. Running the FME Workbench: The script constructs and executes the FME command with the provided IFC file paths and other necessary parameters.I am using a PythonCreator at the start of my FME script to catch these arguments and read with FeatureReader. Currently, when I look at the FME log after I run the external Python script, I see that the paths are not parsed as parameters. 

My question is about the following: I want to create Geopackages from about 20 Oracle spatial datasets. Each dataset must be stored in a separate geopackage.For Example: Oracle dataset 1 must become Geopackage 1, Oracle dataset 2 must become Geopackage 2.  The names from the Oracle dataset must also be copied into the Geopackage.In addition, each Geopackage must be zipped.Is there a way to automate this in FME? I was already thinking about the AttributeExposer, but I can't get it to work.Thank you in advance.

Hi, I was hoping to create a workbench that has a base surface and a target surface and finds the volume between the two, is there any way to do that with the below transformer ie. make the base a surface with elevation differentials?Any suggestions appreciated!Thank you.  

I know in the Esri ArcGIS Portal Feature Service writer there are parameters to control writing out with branch versioning.Is there similar functionality for traditional versioning?If yes, is there a way to have traditional versioning and preserve Global IDs using the Esri ArcGIS Portal Feature Service writer?

When writing my data to an Excel spreadsheet, then I thought to get the attribute names in the first row of the spreadsheet.According the the documentation, the parameter ‘Output Field Names’ only has an effect ‘[...] only if the sheet or named range is being created or has been dropped or truncated prior to insertion. Otherwise, attribute names will not be added to existing worksheets or named ranges.’So, I drop and truncate what ever I can… 😂 However, while ‘Overwrite Existing File’ can be set to yes or no, and it sticks to the writers settings, the in the documentation mentioned parameters can be set to yes, but the next time you open the writers parameters dialog, your setting is back to no.The problem is most likely related to

Hi, I'm trying to populate the "To" and "From" attributes in the Line feature. I have points snapped to the line feature, causing the line to split at the point. I need to fill out the "To" and "From" attributes. I tried a certain approach, but it didn't work:I buffered the point feature and used LineOnAreaOverlayer, and then the Coordinate extractor to find the start and end points of the line.If there is any other way I can use to accomplish this task, please advise.Thanks!

Hello, Using FME Workbench 2022.2 and am able to connect to ArcGIS Feature Service (10.9.1) via the reader with a supplied token (manually). Is there a way in FME workbench to automatically regenerates the ArcGIS token everytime the workbench is run? ThanksAnthea

Hi  I have a workbench that I use for making ortho photo’s. I’m using this same workbench for over 4years now and since last week I’m getting always the same error. It’s says: jpeg2000 writer: Could not perform compression. I don’t know how to solve this, as it has worked always before… I installed the lastest FME form yesterday. I get the same error.   I don’t know for sure, but one time I looked at the edit header option under tools to solve something, but I don’t think I changed anything. Could that result in this error? 

Hi, few days ago I open a post :Best answers it was ok when I try with just one watercourse, but with 2 or more it’s not working. I tryed many days but without success, I don’t know how to set the accumulative lenght custom transformer to work with many watercourses. All segments that are part of a watercourse share an identifier (gwlnr) In attached there is a gpkg and .fmw. with the project in FME thanks in advance  Custom transformer accumulative lenght 

Hi all, Is there a way of exposing the transformer name as an attribute value? I'm trying to create a generic Emailer in which all the transformer "rejected" ports feed into, allowing easy identification as to where the error occurred in the workspace. Currently I'm creating a separate Emailer and writing the transformer name in by hand for each point of failure. I'm running FME Desktop 2019.2 :)ThanksAlex

I have a scan of an old map, that I want to geo-rectify so that it sits neatly under a vector dataset of property boundaries.I am following the example at this link “Adding GCPs to a scanned topographic map”RasterGCPSetter (safe.com)I have picked three GCPsI have a JPEG Reader for the scanned mapI use a RasterGCPSetter to set the three GCPsI then use the RasterGCPApplier to apply the GCPs (I downloaded GCPApplier from the hub)At this point it all looks great. The Inspector shows that the scanned map has rotated about 10-15 degrees. I am only using three GCPs, so this is an expected result.I then use a GeoTIFF WriterBut the GeoTIFF output has no rotation :-(What am I doing wrong? How do I write out a raster that is rectified?

Hi all,I have geometries (roofs) and I will use the transformer donutbuilder for further processing. The incoming polygons are all planar. The transformer “DonutBuilder” stopped with this rejection code:INVALID_GEOMETRY_DEGENERATEI was hoping to solve the problem with the “Geometry Validator” (fix degenerate or corrupt geometries). But all geometries were ok according to the validator.How can I avoid this error?Does anyone have an idea how I can solve this?

I have a lot of SDE connection files that I would like to create named connections for in FME Form 2024.I would like if possible to automate this by creating an xml file to import.  I can use the Directory and File Pathnames Reader to get the path and the name for each sde connection file, so I am thinking I could use FME Form  to  create a xml file with all the entries I need and import that into the fme_userconnection.data filer whiteout having to do this manually one by one.I do not need to specify anything special in the connections,  version, credentials etc. can all be defaulted, so the 2 values I need are the path and name, which I can get.  I tried making a single conn and then exporting to see the xml format, but al the values are encrypted. Is there any kind of xml template or example xml I could use to see how to do this ?       

I have a process that includes the GeometryValidator transformer with a check on for self-intersections in 2D. The validation rightly captures those overlapping or crossing segments, but it also incorrectly catches vertices that snap to another segment. These kinds of geometries can be correct, as in the case of a trail that has a T-intersection and loops back onto itself.I’ve not found a mechanism to allow these kinds of errors to be considered valid. Does anyone have a work-around?

Hi,I have a layer of hydrographic network lines. A watercourse is composed of one or more segments, which share an ID. I have two attributes, abscissa_start and abcissa_end, which correspond to the length of the segment in a sequence. For example, in the attached image, I have a watercourse, where the first segment measures 50m, so start_abscissa is 0, and end_abscissa is 50, the second segment measures 80m, so start_abscissa must be 50, and end_abscissa must be 130, and so on. I need to find a way to be able to calculate the two fields abcissa_start and abcissa_end in FME automatically.The segments are always digitised from the origin to the mouth, and the calculation must be done taking into account as the first segment the one at the mouth. They already have a lenght field. Thanks,
