Transformers

Hi, I have many polygons with height attribute. I need to dissolve the adjacent polygons and keep the max and min height of polygons dissolved. The problems it’s the quantity of polygones that are dissolved it’s random, can be 2, 5, 50, 100 or more. I made a dissolve with generate list, then a ListSorter but then I don’t know how to get automatically the min and max. I think to use attributeCreator with Arithmetic Editor after the ListSorter but I don’t know how to set it to get systematically the min and max of entities dissolved Thanks

Hi, I tried it with a mod counter, Inputs seem to work but no output at all comes out of the custom transformer. I am passing all attributes (not many anyway) into the custom transformer. It makes no difference I am trying to add a Z value to each point (frorm vertices). With the TIN I get a much cleaner result than with a raster, but it slows down the entire process x4. Thanks in advance for any suggestion.

is it possible to Exporting OLE Civil 3D Objects From Drawings to excel

Hello, So I am having the time of my life with Italian WMS’s 👌 and some of them even have some table data queries connected to them. I would however like to get the table information for more than one feature at at time, instead of opening in PRO and click each polygon and collect. Knowing that FME does not support standard GetFeatureInfo yet then I’m speculating if someone has created some artful way of achieving this anyway (sure there are plenty of those). So far my idea is to fetch a center point for each of my respective polygons, do coordinate extraction and then add those values to a standard HTTP based GetFeatureInfo request with some FME string gymnastics. The WMS in question is this here: https://wms.cartografia.agenziaentrate.gov.it/inspire/wms/ows01.php? The layer being: CP.CadastralParcel And the information being fetched from the query being: InspireID LocalID InspireId_namespace Label NationalCadastralReference All suggestions what would be the best way to achieve this

I have a dataset of around 200,000 records (point geometry with approximately 10 attributes). I am using the Change detector transformer to update only those records that are updated and to add new records or to mark some as deleted records. I am using the Feature Writer transformer to write the data into an ESRI Enterprise geodatabase in MS SQL in Azure Cloud. Source data resides in the same geodatabase in Azure Cloud. !!! FME Server is installed on premise, not in Azure !!! When initializing the ETL by truncating the destination table and initial loading of the data, the 200,000 records are written in about 7 minutes. !!! There is an index on the attribute that is used as Primary Key and that attribute is indicated After the initialization, the time to perform the ETL is still low (5-8 minutes) if there are no updates on data, or if there are few updates. However, if there are many updates (i.e. 100,000 updated records) the time increase dramatically to 4 hours. Data is written in 3

Translating using 2014 igds_text sixe 8 translates to Height and width 0.08 however translating using 2021 using the same parameters it translates to 0.00 and if it is a multi line text with 3 lines of text it translates to 0.03. I did try other scaling sizes even up to 20 and the results were the same. Please advise Since I need to do an upgrade and don't want to have to redo all of my text items I installed and tested FME 2017, 2018, 2019, and 2020.. It appears that the text change happened in release 2020. I can use the same FMW file that I created using 2014 and it works fine for 2017, and 2018.. I did have a glitch using 2019 but once it ran the data was correct. Starting in 2020 the text sizes were all messed up. I am hoping someone can advise me on what may have happened.

As the title says, I have two different point feature classes, and then a table in the geodatabase. Point A has a unique field value that matches from the point to a record in the table and then, that record in the table has a unique value that matches to Point B. I want to use this “connection” and the vertexcreator transformer to create a line from Point A to Point B, for situations where they match, but I am stuck at the moment and can’t seem to connect the dots. Pun intended.

I have been tasked with connecting to an FTP site, retrieving a csv file, parsing that file into multiple Excel worksheets within one workbook and then FTPing the Excel spreadsheet back to another FTP site. I have all the component pieces working, in 6 different workbenches, the download of the original csv file, the parsing and writing of the data for each Excel sheet and creation of the four individual worksheets and the upload to the destination FTP site. However, I have been advised by the local FME Admin that the process should be housed in one FME workbench. And in order to achieve that, instead of downloading a physical csv file, I should be downloading the data as an attribute so that all of the subsequent processes could be housed within one FME workbench and the attribute data shared by each subsequent process, leaving no artifacts at the conclusion of processing. I have created one FME workbench and copied all of the processes into it and made all the adjustments to User Par

Hi I’m trying to combine some linear events with a routes geometry. The segmentation works fine. The only problem I have is that the from-to values are no longer correct in the new geometry. How can I update them?

I am using SQL Executer but in the output port I am not getting the attribute exposed automatically. My SQL expression I am only counting the inputs so I cannot expose the attribute using “Populate Attribute from SQL”. I cannot use Attribute exposer every time I am using the SQL. Is there any other way to do this.

I have about 20,000 adresses and 10 locations of the same sort of destination (eg. a doctor). I have already a network. I'd like to calculate the shortest path between each adress and the nearest doctor over the network. Is there a way to utilize the shortestpathfinder for this? I tried the fromToBuilder to create from-to-lines. However, the fromToBuilder requires a join field for each from and to location. Which I would then have to create manually for each adress (and so create 200,000 paths; 20,000 * 10). The shortest path could then be recalculated after the shortestpathfinder to get the closest doctor for each house. Is there perhaps a more efficient way to do this?

I am using FME(R) 2022.1.3.0 (20220928 - Build 22630) I noticed while working with ArcGIS Data (FileGeodatabase), that when I usethe “DatabaseJoiner” Transformer to join attributes with curly brackets inside its values, the curly brackets are gone after joining. e.g. Original Attribute value: {12C300A2-64C3-4494-A1E2-430CC5C5C7A9}joined value by DatabaseJoiner: 12C300A2-64C3-4494-A1E2-430CC5C5C7A9 It this a known behaviour? Why would it get rid of the curly brackets? Anything to do against it?

Hi All, I’m working on a workflow to project a DWG from one coordinate system to another. The workflow works fine but am having issues to write autocad_oriented_arc into the DWG final output. I did some test to write it to GIS format and those autocad_oriented_arc write ok but for some reason can’t get them to work in DWG format, I’m sure that am missing some settings in the writer because the visual preview shows those arc fine, see below: I’m using the following: FME(R) 2023.1.2.0 (20231110 - Build 23641 - WIN64) Writer Autodesk AutoCAD DWG/DXF parameters as follows: Thanks!

Five months ago, I created a small FME application that would login to a state controlled secured FTP server and download a file to a local drive. Putty was used and files were generated for local use and for the state. That application was working fine, however, the agency that made the request was not able to approve the process in the interim. Now, five months later, when I run the application in FME, the login is rejected. If I use the exact same parameters to manually download the file with WINSCP I am able to login and download the file without a problem. Nothing has changed in the setup of the FME. In the attached image, I show the three transformers and their parameters that I used to download the file. Five months ago it worked. Now it does not. Manually, it works. Via FME it does not.I am not sure if this is problem in the FME, an issue with my local network security or an issue at the State ftp site. The error message is as vague as described in the documentation.

I’m trying to repeat the same process on each group of features that represent each door (every door consists of many features having the same value of door_id) . on the other hand , the process that i want to create is detecting that line on green for each door and drawing it using the LineBuilder . So for exemple , if in my input i have : 200 features , every 30 or 40 features share the same door_id value (so there are say 6 doors in total ) my output : 6 features (each feature is that green line , with the attribute door_id)

Hi All, Is there any writer for AutoCAD Civils 3D (.dwg)? There’s definitely an AutoCAD Civils 3D and Autodesk AutoCAD Map 3D Object Data Readers but can’t find the same writers?

Hi All, I’m trying to read an Autodesk Civil 3D file in FME(R) 2023.1.2.0 (20231110 - Build 23641 - WIN64) but gives me the following error, see below: AutoCAD Reader: An error occurred for dataset 'filename.dwg', in function C3DReader::processAeccAlignmentEntity.

Hi, we have tiff files with rgb values. Is there an easy way to transform this tiff file in hsv color space? Something like inside the transformer “rasterexpressionevaluator”? thanks in advance

Hi, I have a table with many points, with an ID and two attributs, like this : I need to “dissolve” the points and get just one point by ID and in attributes get “Yes” if at least one of the original points had “Yes” as value, like this: Is that possible with some transformer? Thanks

Hi, Is there a way to change the color of the font for the part of the text that matches regex? In the scenario below I would like to put in red only the double spaces in Excell At the moment is highlighting the whole text in excel

Hi, I would like to create a FME app that will allow users to check the gdb for wrong attributes. Each time the attributes in the gdb will change hence I need to find out how to do it automatically/dynamically.

I’m dealing with a rather large JSON file. The issue I have is that some element values contain literal quotes and double quotes, and these are causing Rejections in the JSONExtractor. The quotes/double quotes are not escaped in the original source. Is there a way to escape these automatically with other FME JSON transformers? My efforts to fix thus far using the StringReplacers have resulted in errors throughout the entire JSON string, since quotes/double quotes are native to JSON formatting.

Hello, We have been troubleshooting this FME translation for a while and can’t figure out a solution. The Inserted, Deleted features of the ChangeDetector write reasonably quickly but the Update features are writing so slow it will be unusable, GIF for reference. Things we’ve tried without any differences: Indexing all fields in ArcCatalog Indexing Just the Match Column fields (3 Fields to make a Unique ID) Indexing and using a CRCCalculator field for the Match Columns Adding a FeatureHolder after the ChangeDetector Adding a AttributeManager after the ChangeDetector removing unused fields Writing to a File Geodatabase (SDE is ultimately the goal and being used in the gif below) Not Checking the Geometry in the ChangeDetector Changing Transaction types in the Writer Changing and testing various other settings in the transformers and writers Thank you for any suggestions!!

Hi there, I have following input: a list with unknown/varying keys and values What I need: the name of the keys as attribute values Examples What I already tried: ListHistogrammer This has no effect. Is it because it’s a “nested list”? Cheers,Maria

Parcels are created, removed or changed in GIS, but we also have a CAD Map3d basemap that we also maintain. One of these basemaps contains a text layer that has the address number for each parcel, what I am trying to do is compare the parcel address number from the GIS against the cad basemap find out which ones have changed, removed or inserted then make the changes to the cad file. I have already setup readers for the GIS and CAD parcel polygons and using a change detector I know what is different compared to the polygon basemap, but now I need to take that result and check it against the text in the cad basemap and update it. for some reason the number of changes don’t seem to match when I compre the text. how would you suggest I attempt to do this, is there something I am missing.
