How to efficiently filter features with an IFMECompositeSurface geometry from those with an IFMEFace geometry?

A while back I developed a workspace in which I wanted to calculate the 'outsideWallArea' of buildings. That is, whenever buildings are directly next to each other, the touching wall that they both share, shouldn't be counted as an outsideWall. So for example, consider these 3 buildings (cubes with sidelength of 1);Now both building 1 and 2 would have an outsideWallArea of 3, and building 3 would have an outsideWallArea of 4 (note, the floor and roof do not count as wallArea). For this purpose, I used a SurfaceOnSurfaceOverlayer on the buildings. In this way neighbouring buildings fall apart in individual IFMEFaces, and by using the _overlaps attribute neighbouring walls can be excluded from the (outside)WallArea. The 'problem' now is that disjoint buildings are not overlayed to other buildings, and these keep having an IFMECompositeSurface geometry, where neighbouring buildings fall apart in IFMEFace geometry features. So after this step I need to distinguish betwe

How to do an automated texturing with oblique aerial photos

Are there possibilities to do an automatic texturing with oblique aerial photos in fme? Ther eare some software like CityGrid or RhinoCity who can do that. They only need some parameter regarding orientation of cameras. We have an production workflow for CityGML buildings in fme and we would like to texturize within the workspace or by implementing existing functions or something else. Does anyone know if this is possible by using FME?

Oracle SQL connections are persistent, regardless of the "Persistent Connection" setting

I have a workspace that has two SQL Executors connecting to an Oracle database (the same database connection). In between there is processing that happens. It appears that FME is keeping the oracle connection open from the first SQL Executor for the entire duration of the processing, and using the same connection when it runs the 2nd SQL Executor. This is causing a network timeout error to occur. To prevent this I have tried unchecking the Persistent Connection option in the 2 SQL Executors, but still get the same behaviour. As a test, I have logged the oracle session ID from the first SQL Executor to the log file, and in the 2nd SQL Executor I have logged the session ID and session duration. Both session IDs are the same and the session duration is the entire running time of the workbench. See attached screenshot for workbench, the decelerator is to simulate processing time. So to summarize, the Persistent Connection check box doesn't do anything in FME Desktop or Server.

Creating DEM rasters and hillshades from Lidar

I'm creating DEM rasters (1m cell size) from Lidar using RasterDEMGenerator. Then Hillshades from the DEM rasters using RasterHillshader.I'm getting hillshades that look like stacked contour layers.I believe the hillshades "should" be smooth surfaces (especially Lidar surfaces) so I'm not sure what I'm doing wrong.I've attached my model and sample output.

Why does the GeometryValidator report self intersection on the start/end point of the outer ring of a donut?

I have a donut geometry (see WKT below) which I am trying to validate. Using the GeometryValidator only looking for self intersections I get an error on the start/end point of the outer ring: Error report:Coordinates from the inspector: I would expect this to not be reported as a self intersection since polygons normally require intersection at exactly that point. Why is FME reporting this? I have tried using both FME Desktop 2021.2 and 2022 beta.

WHERE clauses in FME

Hello, I am a basic user of FME and have created a workbench merging many tables. I need to add a further table, but before I use the FeatureMerger I need to specifiy a WHERE clause on the reader. I have tried doing thison the reader with no joy. I have also tried with the FeatureReader and no joy. I cannot find any help documentation in the reader to help me with syntax. Is there a simple transformer I can use? I need a very simple clause to pass only certain attributes from one of the fields into the next transformer. Can someone assist please? Harriet

Merging different geometries into one polygon (3D)

Hi there guys (and girls), I've been trying to combine several 3D-geometries (arcs, polygons, lines) into 1 big polygon. What I have now are seperate parts (a window, a floor, a wall and so on), but what I actually want is a clean building that is only clickable as a whole. I already managed to combine the different geometries into a geometry collection with the Aggregator Transformer, but I was not able to write this geometry to the destination file (OBJ). Does anyone have any idea how I could solve this problem? I am looking forward to hear from someone else from this planet soon,Claire

Convert one kml format to another template, the best way to go about it

Hello!We have a new software package that imports KMZ/KML to another KMZ/KML format, and cannot take the standard google earth created KMZ. This is causing us issues, as 99% of the kmls we get to import are in the standard XML Format. What is the best approach I can take or transformer to use in order to convert the different KML formats? I attached two examples. One we received from someone to import, and the template that the vendor needs to import.

How to iterate through GDB feature classes?

I've got a very big feature class which contains more than 12,000,000 polygons and I need to use TopologyBuilder and other transformers to do some processing, but it took too much time for TopologyBuilder to process the dataset. So I came up an idea that I split the dataset into several some small feature classes which contain less polygons. Now I only need to run my workspace repeatly through WorkSpaceRunner, but WorkSpaceRunner seems can not process feature classes in the GDB one by one, I have to export feature classes in to separate GDBs to get it work, but exporting processing also took a lot of time and made my folder very complex. So is there any way to iterate through GDB? I'd appreciate any @suggestion, thank you!

Text to Graphics: Complete removal of .shx/.ttf Reference

I am in the process of converting DGNs to SVGs for use as symbols in ArcGIS Pro. I am able to filter out the Text in the DGNs and assign a stock Windows Font. However the text reference is not being passed to ArcGISPro and the the text component of the symbol is lost. I am looking for a transformer or a set of transformers that will allow me to take the text in the DGN and convert it to a graphic, that DOES NOT reference a Windows stock .ttf file. I have looked at the TextStroker but the outputs are inconsistent and messy looking as compared to the original DGN text, and I am also having trouble finding a way to fill in the TextStroker output. To clarify, the ETL that I currently have successfully displays the text in the output SVG in a Web Browser. The only location that does not see the .ttf reference is ArcGIS Pro (the final, required, destination).

How can I setup my FME workbench, so Microstation CE knows the coordinate system?

The data conversion from the oracle database to dgn works fine. I see in Microstation that the coordinates are identical with the counterparts in the Oracle database. However, Microstation doesn't seem to know that it has a coordinate system. It says <coordinate system not set>. In processes 'downstream' requires that the dgn files have a coordinate system for further usage. This is now a manual step, that we want to avoid. Is someone familiair with this and knows how we can setup FME to write the coordinate information?

Can you write to geodb relationships from any source data type?

Hello thereI was wondering if it's possible to write to geodatabase relationship classes where the source is not a geodatabase, so you don't have the "OBJECTID" to set as the "geodb_oid". I'm reading in some CAD data and am inserting records into 1 feature class and 1 table in a defined File Geodatabase that already has the relationship class setup (non-attributed), and want those 2 objects related. All the examples I've seen of writing to geodatabase relationship classes seem to have a Geodatabase-type source with already-defined OBJECTID values as attributes. I may have missed some documentation, or have done some tests incorrectly, but is it possible to somehow create the "geodb_oid" at runtime or would this have to be a 2 step process (i.e. 1) write data to feature class and table and 2) write relationships)?I know this is a bit vague but hopefully there's enough information that someone knows the answer!Thanks

I installed FME server 2021.2.2 and I have a problem in the gestion of the coordinates system NTF.Lambert-2E-ClarkIGN. It seems that FME server doesn't recognized this coordinates system and thinks it's NTF.Lambert-2C-ClarkIGN. We tested with FME desktop 2021.2.2 and FME server 2021.2.3 and the coordinates system is recognized. Do you know if there is a problem with FME server 2021.2.2 and the coordinates system NTF.Lambert-2E-ClarkIGN ?
