Transformers

Using the same polygon the Generalizer (Douglas, tolerance=0) returns different results depending on the orientation of the polygon.Any explanation?

It appears the LabelPointReplacer removes the z-value from 3D point features and replaces it with NaN. I’m using FME Form 2024.0.3.0 as our IT-department isn’t fast enough with the updates 😑. Does anyone know if this is fixed in a newer version? Now I 3D-force it with the old z-value.

The three readers need to match up exactly. I would like to be able to see how many are perfect and how many need to be fixed. I would like the ones that don’t match to be dumped into an Excel spreadsheet that I can look at and make the necessary corrections. This is what I have so far. Top and bottom do match, middle one deliberately does not. What do I need to do and how should I proceed?

Hi, we have a dwg file and we wanna use this file in a gis software. We are aware that the fme cannot do georeferencing.Our approuch ist to use the Offsetter transformer to “move” the data to the correct place!That would be enough for us! So fist we used the AutoCAD DWG/DXW Reader to read the dwg file.Do we now have to set a coordinate system before using the Offsetter?Inside the inspector tha coordinates looks like this: Can anyone help us please?

I know there seems to be lots of topics around this but just can’t seem to get it to work.I have a configuration file that I read in at the start of a workbench. In that file is a range of attributes that I turn into user parameters.One of these is to define a specific field from a table which I have called _extractSubjectParcelQueryFieldHow do I use the contents of this variable to be the attribute that I want to expose?  In my case the actual value of the user parameter is ‘land_id’ but this can change depending on the data coming in.  

I have 2  coordinates in Denizli,Turkey . I have lang  and long. Sample 2 coordinates :U1  37.787464°  28.780846°U2  37.751292° 28.864560° I use reprojector transformers convert the data wgs84 to ed50turkey. I use EPSG:4326 and EPSG:23035 .It converted wrong coordinate.  The true coordinate of ED50 Turkey :  U1 656858.976    4183906.006U2 664311.027    4180035.990 Thank you! 

One thing wish FeatureJoiner had was a CROSS JOIN / Cartesian Product mode to create every permutation of Feature Set A vs Feature Set B  (Eg.  When creating To-From Lines between every possible Origin Point and every possible Destination Point).Custom Transfomer FeatureCrossJoiner is not anything really radical in how it gets FeatureJoiner to do this by creating a temporary dummy Cross Join attribute, but perhaps simplifies the process for some users.https://hub.safe.com/publishers/bwn/transformers/featurecrossjoiner 

Hi,I have a fgdb, I want to drop all existing features classes within the fgdb and write in a new one. Is this possible?ThanksB

Out of the blue, I've started getting the below error message with my workspaces running on flow which talk to SharePoint: FME Flow error logI did some of my own digging, and found this community post:where the user had a similar issue. I have uninstalled my sharepoint package (1.1.6) and downgraded a version but it still doesnt work. I also upgraded it to 1.1.7 for good measure and that also didn’t fix the issue.  I am not downloading these packages directly off of hub because my install is on a remote server, so i have to copy the packages across before installing. I know partial installs can occur doing it like this, but error came out of the blue and I’m not sure why. There was an OS upgrade on the remote server prior to this, but if something was inadvertently deleted, I would have thought that reinstalling the package would restore what was missing. FME Server 2022.2.5Build 22795 - win64 Thanks :)    

Hi,I am working with CityGML data and using FME to process and transform buildings from a 3DCityDB into CityGML output. I know I can use the 3DCityDBImporter/Exporter for this but I would like to create a custom FME script for more control.I am trying to transform attributes from the 3DCityDB into a format suitable for CityGML output, specifically list attributes like citygml_function{}, citygml_function{}.codeSpace and citygml_usage{}, citygml_usage{}.codeSpace. These attributes are stored as strings with values separated by --/\--, and the corresponding URLs (codeSpace) are also in a similar delimited format.I attatch one building with these attributes in csv format as an example.The end result should be like this feature (building):Have anyone done something similar as this? Im not very used to working with lists. Would appreciate the help, thanks in advance!

Hi, I am trying to edit the workbench from https://fme.safe.com/blog/2016/05/point-cloud-power/ so it splits the polygon into the number of parts or area I provide. I cannot figure out how to change the PointCloudCoercer to allow me to do so 

Hi there,  I have a shapefile with real estates that enclose several buildings. I want each polygon in the real estate layer to inherit the attribute entries for the buildings that lie inside each real estate polygon. Some of these entries will be the same, but I want all unique entries for buildings within the same polygon to be written to the same entry.  For example. Three buildings lie within one real estate with attribute entries “Residence” “Grocery store” and “Recidence”. I want these attributes entries to be concatenated into a single attribute entry, separated with comma, in the real estate layer, but with duplicate entries removed. So, the final attribute entry should be “Resicence, Grocery store” for the real estate polygon. Is there any way to achieve this in FME?

Hi All! Just a hopefully quick question: I want to write data to ArcGIS Online, and i want to do it dynamically, but it isnt really working out, here are my settings: I want to dynamically write data to ArcGIS Online, but i get this error message:  Can someone tell what im doing wrong?  Thanks in advance!

Hello, my previous post was not well Described apparently, i need to split .las just like that. please if you suggest any workflow do describe it a little more than just the name of transformer as that is usless for me (i dont really know how to use FME) 

Hi All, I’m trying to dissolve thousands of polygons from different feature classes into a single shape in FME. The idea is to obtain a single external boundary after merging/dissolving all the polygons. The current dissolve transformer gives me an error while trying to dissolve the polygons.Parameters in the dissolver are set to default.Is there any ‘hard dissolver’ option to merge the following?  Thanks :)

Hello to all,I need to add a missing property into an existing Pset. I tried the workbench shown by Liz in the post “Updating IFC example” but it doesn’t work in my case. Before testing with an Excel sheet contaning GUID and properties to add, I just test to add manually a single property:First, I created 2 attributes:Then I used the GeometryPropertySetter:With the XQuery:I find my previous properties in the “Proprietes” Pset, but I don’t have the new one “TypeVitrage”. Did I forget something or do I have to use “IfcPropertySetDefinitionCreator” ? Thank in advanceBest regardsBruno

I want to pull Google BigQuery data in FME and write as shapefile. Can somebody help me on how to do that?

Hello community!I am working on an analysis to calculate the percentage of incline or decline from railway level crossings. This means the incline or decline along the road that crosses the railway.The desired result is six percentage values. Three for each side of the track (viewed in increasing kilometer (M-value)). The three intervals are 0-4.5 meter, 4.5-8 meter and 8-18 meter, measured from the outer edge of the railway track.It is desirable that the length is measured along the road.Decline from the level crossing should be shown as a negative percentage value, and incline as a positive percentage value. Based on the client's wishes, I have divided the analysis into smaller tasks:Add a property that shows whether the road lines are on the right or left side of the railway, viewed in increasing kilometer (M-value). I have tested the LeftRightSpatialCalculator, but for some unknown reason it always gives me the same side on both sides. I see that TopologyBuilder is mentioned in the

One feature has 40 vertices and the other 41, but ChangeDetector using “Lenient Geometry Matching” option says they are the same. It's right?  

Hi,I have a shape with polynones. I want to select 30% of the polygons at random. Is that possible?    

Hi community! I've been trying to formulate an efficient workspace that would:Extract feature service URLs from an excel sheet (many have the item ID number at the end)Download the GIS data from each feature serviceTransform the idea with typical cleaning upWrite out to a file GDB on a local server drive For steps 1 and 2, I've been experimenting with HTTPCaller and FeatureReader but haven't yielded a successful extraction yet. I think 3 and 4 will be straightforward, but if there any any suggestions (specifically with getting from 1 to 2) welcomed, and appreciate any feedback in advance!

Hey all,So I upgraded FME Desktop to 2024.1 (through ArcGIS Pro installation) and opened up an exisitng workspace I had created in a previous version. When it opens I get the message stating:Transformers are used that are not installed: 'CenterlineReplacer (version 6)'https://docs.safe.com/fme/html/FME-Form-Documentation/FME-Transformers/Transformers/centerlinereplacer.htmWhy is this happening? I have no option to upgrade the existing transformer and it disappears from my workbench and when I try to search to add another ‘CenterlineReplace’ transformer, it is missing from the list.I have ran a repair on the installation but it is still missing.

I need to write an existing feature class to a new feature class (with some modifications) in an Esri SDE database and require that the attachments to be included and properly linked. When I write out to the new feature class, none of the attachments appear to be persisted in the __ATTACH table. What do I need to do so that the new feature class retains the attachments?
