Transformers

Hi,I have a shapefile with municipality polygons and I am using the SpatialRelator with the option "Requestor Touches Supplier" to count the number of neighbours of each polygon. However, I need to know the lenght of each common border for all polygons. Is there a way to output that information? In QGIS is posible (as explained on this link https://spatialthoughts.com/2020/04/08/calculating-shared-border-lengths/#more-962 ) but it's not very fast to run, therefore I would like to do the same in FME.Thanks and best regardsOscar

I want to mosaick 188 netCDF files into a single netCDF file. I get the errorNetCDF writer: Failed to end definition. The error was 'NetCDF: One or more variable sizes violate format constraints'The data is a DEM, so only one band which is elevation.I have attempted both "Classic" and "64-bit Offset" ParameterWhat am I doing wrong?

Hi,I want to run some Rscript and so installed an R-interpreter and installed some Libraries. As a test case I downloaded the workspace from a rather old article "RCaller: Ins and outs of using R in FME". The workspace is from 2020 though so i ran it on both 2019 and 2021 versions but it returned the same error in both cases. Actually the exact same error as mentioned in the article itself: "Failed with exit code 1 when executing R script. Output was: Loading required package: gsubfn.......". Now the article mentions to check spelling but as the workspace is an exact copy from safe I expect that to be tested and ok and furthermore that is just not the issue as the line "fmeOutput<-data.frame(meanEst,meanAct, r2, m, k)" in the Rcaller works just fine if I just pick one of the columns for output, irrespective which one. e.g. "fmeOutput<-data.frame(r2)" But the moment I comma separate a few data frame colu

Hi, I am creating contour lines and contour polygons from a raster geotiff file with 50m intervals. In lowland areas near the sea a lot of tiny lines/polygons are created wherever the elevation fluctuates around value 0-m. GDAL has a parameter (Offset from zero relative to which to interpret intervals) which allows setting an offset so as to reflect only significant low elevations (by setting it to -5 for instance). However this parameter is not present in the ContourGenerator transformer of FME.Can you think of a workaround for simulating such behavior? Otherwise is it easy to call the GDAL function from within FME?Thank you! Best regards, Olivier

I have a workbench that takes a zip file as a user input and checks if it contains a shapfile. If it does, it goes to a FeatureReader and then on to a shapefile writer.  I have tried every setting I can, but I can't get it to generate an output shapefile if the shapefile writer is set to use a Dynamic Schema Definition Am I missing something, or is this just not possible? The log says the workbench ran successfully, but no shapefile was created: > Translation was SUCCESSFUL with 9 warning(s) (353 feature(s) output)>FME Session Duration: 3.1 seconds. (CPU: 0.6s user, 0.8s system)>END - ProcessID: 940, peak process memory usage: 116280 kB, current process memory usage: 1116

Greetings,I have a Feature Reader transformer, reading a list of dwgs. Sometime after I initially created the Feature Reader I needed to expose additional attributes, and so did by adding to this list......however, the newly exposed attributes are not showing up in my output ports. I'm not seeing the Feature Reader in the 'Update Readers' command, so am not sure exactly how to get the newly exposed attributes exposed. Any pointers would be appreciated.TylerFME WorkBench 2021

I am trying to convert a CAD file in GDA 94 to a CAD file in GDA 20. But it is creating the output CAD file of very less size around 12 kb. Please suggest.​

Good day, I'm using FME desktop to create a mosaic dataset of some imagery in a file geodatabase. In the footprint attribute table there are default fields "Name", "GroupName", and "ProductName" that are able to be edited in ArcGIS. Is it possible to write this data to the mosaic dataset in FME? Right now I'm populating these attributes in an AttributeManager transformer, but they are obviously not being added to the mosaic. The "Name" field seems to be populated with the basename of the rasters I'm adding I'm using FME Desktop 2021.0 with the ArcGIS Pro 2.8 data interoperability extension.

How to extract Revit Shared Parameters?And how to extend the built-in parameters received from Revit?

Hey! I have a a road network that is split into several features. They represent different values of the road. Example: 1 layer describe surface and another width. So the length of each line in the layers differ from eachother. I would like to merge these together and i wonder if anyone have a solution?  So far I've tried to Take the endpoints from all the lines. Bunched them together and then used them in one PointonLineOverlayer for each Line Feature to split all Lines at the same spot. Now I'm unsure on how to join all the features to 1 Line features with all the attributes i want.  Example Picture:  

On my fme server is a workspace for download which I can start with a webhook. I want to use that webhook in a Python Script. Are there any examples for calling the webhook and receiving the data in python? Best regards Gerhard

I am using Aggregator and HTTPCaller in conjunction with eachother to create an API POST URL and am having issues with the Aggregator output and URL encoding.  I'm using Aggregator to concatenate and merge records and am using a separator of "&fee_id=" as the field will end up as part of the query string parameters:The output is correct:But when I run HTTPCaller and view the URL that ends up getting generated in the translation log, only the "&fee_id=" that was added by the aggregator gets messed up.  Example:

Dear community,I try to write an ifc-file, converted from a dwg file. Simply extruding a block and using the extrude for IfcWall, IfcOpeningElement and IfcDoor. (I am going to add the attributes later). Now the only thing that I am missing is the ifcrelfillselement and ifcrelvoidselement. I followed the instructions given by the explanation on the FME page "Industry Foundation Class STEP Files (IFC) Feature Representation" and the hints given by @dominik​ concerning this issue. But I am not quite sure, where to add the ifc_opening_id and what values to assign to it. Could someone help me out here?Thanks a lot in advance,Morten

I have a dwg in CAD, it doesn't have a projection, I need to convert this to a shapefile, how can I add the British National Grid and move the drawing to the correct co-ordinates?

Our team are trying to create a workbench which will be used to answer user data requests. The workbench should provide a packaged export from our Oracle database, including a schema definition, metadata and various file type(s).  I'm trying to make this as simple as possible by using parameters for the user to input, including table name and spit out folder at the end however I'm stuck when trying to create a parameter for the table name we want to download using the Esri Geodatabase (ArcSDE Geodb) Reader.  I've actually managed to work around this for the metadata by setting a default table, using the merge feature type option and using a wildcard, then setting a parameter from that. However when I try this with features although I get the geometry I get an empty attribute table.  Anyone have any experience of this or potential better solutions?

Forgive me for what is likely a very simple answer to this question, but I'm still rather new to FME. I'm wanting to use a defined User Parameter (Type - Text) which will then inform my AttributeFilter transformer (where the user parameter directly corresponds to a specific field of the dataset being read by the AttributeFilter transformer). However, when I set the transformer parameters as per the screenshot below, I don't then get the expected output, i.e. the dataset filtered for that specific value. Is there something I'm missing? Thankyou for taking the time to read this post. 

Hi everyone, I am trying to get the value of the first table (that only has one row with info about xmin, xmax, ymin etc.) into the 2nd table. The second table has more rows and my wish is to have all the rows in table to get the same value for e.g. xmin from the first table. However in the 2nd table only the first row gets the value of the first table, while I want to have all the rows the same value for that column. Does anyone how that might be achieved? In case my question is not clear, just let me know.

Hi! I am trying to read into FME a series of images (jpeg/tif/png) and then match them to a different datasource and rename them using pieces of information from both sources. All works well. But. I have some files which contain special/accented characters which aren't being read in. For example the filename below  Anadolu Koyu PLAN_IZMIT KÖRFEZI TO ISTANBUL.jpg throws an error 'Anadolu Koyu PLAN_IZMIT KÖRFEZI TO ISTANBUL.jpg' cannot be located. Please ensure the file exists and is accessible' The common denominator in all of the errors is the special/accented characters. My question is whether I am missing something and I can get FME to read the filenames and bring them into the workspace, or whether I need to handle these (hundreds of) files manually? All helps much appreciated!

I am converting a dgn file with lightweight polylines to an autocad file. The input dgn file has a size of 70 MB and when I am converting to a dwg the size becomes roughly 97 MB. The dng consists thus of lightweight polylines and during conversion to autocad there is automatically a z component in the autocad file. Based on the following page FME Creates Large AutoCAD DXF Files (safe.com) I included an autocad_original_entity_type attribute in the attributemanager with the following value autocad_lwpolyline . The size becomes then 95 MB. I would like to make the dwg much smaller, how can I make the file much smaller than 95 mb by changing somethign in the autocad writer or doing some kind of transformation.

I have a linear feature and need to create another linear feature perpendicular to the original feature and at a given distance along the original feature from the beginning point.  Any help as to how to accomplish this would be much appreciated.

I'd like to have the value of an attribute as a user parameter.I need to make sure tables I work with comply with a schema. The schema field names are in a CSV, imported without column headers. I aggregate the attribute which leaves me with this output:Is it possible to get the string in col0, row 1, as the default value in a user parameter to ensure my output table conforms to the schema? Thanks!

I have a dgn file that consist of many models ( it corresponds to a building and every floor has its own model) and I would like to import the models as seperate features in FME if that would be possible. When I try to import individual feature types in the dgn reader, instead of the models I get all the level names instead that are present in the models. So the feature types do not correspond to the model names, but to the level names. So for example I would like to get a seperate feature type of a model for floor 1 and of a model for floor 2. Does anyone know how that might be achieved in FMe desktop?
