Trying to execute python file from pythoncaller

Dear FME community, apologies up front for being a novice python userI am trying to use the python caller transformer to execute an external .py file. However my external .py file does not have any classes therefore I don’t know what to do with the ‘Class to process features’ parameter in the transformer. If I run the python caller regardless, it executes my .py script fine, but crashes at the end with this error message “PythonFactory failed to load python symbol `FeatureProcessor'”. This is because I’m using the default ‘FeatureProcessor’ as my parameter for the “class to process features”, which I know is wrong.My python script simply generates a JPG file and saves it to a directory.I hope someone can assist and I haven’t totally missed the point.Regards, Damian

Adobe Geospatial PDF Reader: Text highlight extraction

Hi everyone! I am new to using FME software and I am trying to use FME Form to extract information from a PDF using the Adobe Geospatial PDF reader. I was wondering if it was possible to somehow extract the color of the text in the document. For example, if I had a PDF document with yellow highlighting and blue highlighting, being able to extract the bits that are only yellow and only blue. Thanks!

3d tiles

Hi, I have been working on CESIUM 3DTiles generation, but I am facing challenges because the results are not aligned with my intended goals. Specifically, I am unable to achieve the desired mesh quality. The input files consist of a GeoTIFF with a resolution of 6 centimeters per pixel, and the point cloud data is stored in a LAZ file containing over 250 million points. Despite these inputs, the resulting mesh quality remains disappointingly low. I am seeking guidance on how to improve my workspace and achieve a high-quality mesh.

Can I export source and destination values from the AttributeValueMapper?

I have a very long list of attributes that I have typed into an AttributeValueMapper transformer. I now want to share this mapping with someone (not an FME user), so I would like to export the source and destination values to excel. I see that there is a button to import to this transformer, but not one to export. Is there a way around this, or doing I have a lot of typing to do?

Autocad true color for Autocad block attributes

Hi,I am extracting GIS layers into a DWG file using FME 2017.0.1.1I would like to define the color of Autocad block attributes using Red Green Blue (RGB) codes (autocad true color) instead of autocad color values.The RGB values are defined in an Excel settings file that I call up in the transformer “AttributeCreator” :However in the output DWG file, the color is defined by an autocad_color value (very close to the RGB value but not quiet the same), but it doesn’t write the RGB values in an autocad_true_color attributes.I also tried to create an autocad_true_color attributes defined by the RGB codes of my Excel file but it doesn’t work neither (same output).Is there a known limitation in FME working with autocad block attributes with autocad_true_color? And is there a known workaround?Thanks in advance for your support.Aude

Creating a 3D Photo Mesh with DEM and Aerial Imagery

Hi there, I am trying to create a 3D photo mesh using LiDAR and aerial imagery, but find using the TIN Surface produces a more jagged output, even with a higher tolerance. I was wondering if it’s possible to do this using a DEM and if this would produce a neater result. I am using Surface Modeller to convert the LIDAR to TIN Surface. I then remove existing appearance and hook up the result along with the aerial image to the appearance setter transformer.What should I be using to get a neater output or is TIN the only way to go?Regards, Josh

Subtracting surfaces or solids from others

Hello everyoneI am currently working on a project where i have to create an ifc file from a CAD floor plan.in fact in order to do that i have some issues to solve, one of them is that i have to create gaps in walls for doors and windows, for that i thought of extruding the walls and doors twice using two extruders to create solids and use CSGbuilder to create the gaps but it rejects them , so i thought of extruding the walls and doors only once to create surfaces and use the clipper , however the doors surfaces happen to fall next to the walls , and not precisely on them which lets the clipper fail at calculating the intersection , so i am wondering if there is a way to somehow project the surfaces (for example the doors on the walls) before using the clipper or maybe you have an entirely different idea for handling this problemThank you in advance.

Hi, I'm wondering if it possible to 'data stream' a PDF document? Attached is my workbench. The workflow is: Call a reporting engine via a HTTPcaller which returns the PDF I'd then like to publish this to a datastream service. Is this possible?

I have used the 'filecopy' writer. The workbench works fine within FME desktop but when I run as a 'data stream' within FME server I get a message saying 'There was an Error'. See attached screenshot. I guess the question is, is it possible to 'data stream' a PDF. And if it is, should I be using a PDF writer?

NeighbourFinder not working well on Form 2023.0.0.1

Hi FME Community,I’ve been testing out an old script with FME Form 2023.0.0.1 and noticed one workspace with NeighbourFinder transformer has come to a halt with no clear message of warning or error. The same workspace works well with older FME Desktop Workbench 2022.1. Data size is around 50K rows, however it’s unclear at what progress/rows the halt would happened.I was suggested to upgrade to newer version, anyone encounter similar experience?Cheers,Noe

How to use attribute as xml path in XMLUPDATER transformer

I am trying to use attribute, which reprsents search path, to fill in the XML Path in Update section as shown in the screenshot below. But the update is failed. The original value for the element is gone. From the translation log, I can see the following warnings. But I cannot figure out why it says about “end of file”. Please can someone shine a light on the issue?Thanks.

Best way to represent Esri file geodatabase with 4 Feature Datasets

I have been trying to create 4 feature datasets inside 1 file geodatabase using FME, but it looks like in FME there is no option to create an Esri feature dataset. When I have opened the feature writer, I don’t see an option to select feature dataset.I have a lot of shapefiles that I want to organize by province represented by the Esri Feature datasets and inside each feature dataset there will be points, lines, and polygons (it is not just one type of geometry).Do you know if that’s even possible in FME?

Unique port of DuplicateFilter returning duplicates

Hi,I’ve got a strange issue.I am using a FeatureMerger to match values from a lookup table.Then I use a DuplicateFilter to check that all the terms from the lookup table are used. And strangely, with certain non ASCII caracters, there are duplicates coming out the Unique port ! Another strange thing is that these duplicates in Unique port dont appear when I check for duplicates immediately on the lookup table.So what happens in the FeatureMerger that makes the DuplicateFilter dysfunction ? Here’s what the Excel lookup table looks like. When I replace the non ASCII caracter, the problem doesn’t appear.What to do ?

Update AGOL Hosted Feature Service using ChangeDetector

Hello, I am updating an existing AGOL Hosted Feature Service with changes in a File Geodatabase. The workbench in the screenshot is what I am using. The Feature Service updates no issues, and it does update the feature service. But I have a question:When I add 1 new feature in the file gdb (Updated FGDB Feature Class Bookmark in screenshot), I run the workbench and in the ChangeDetector it shows 1 record Inserted and 238 records updated for a total of 239 records; The only change I made was to add 1 new feature (which I expect to be in Inserted), but why would there be 238 records in Updated in the ChangeDetector when I only Inserted a single record and Updated zero records, should these 238 “Updated” records be in Unchanged?I then reran the workbench it showed 239 records in Updated (which includes the one I added in the 1st run), but I Updated zero records so I would assume these 239 records should be in Unchanged? The ChangeDetector Parameters I am using is in the screenshot.
