Transformers

I have an array of polygons representing a surface triangulation.Because of the source of the data, some faces are vertical which aren't supported in the TIN I'm trying to create.Any ideas on what would be the best way to overcome this? I'm sure its a common issue, be interested to see how others handle it.Maybe convert to lines, filter overlapping lines with different Z values and offset both a small amount?

I’m struggling with the TopologyBuilder transformer and, since I’m sure my use case is quite common, I hope someone might be able to help me. I want to extract the topological boundary polyline from polygons. In addition to the polyline geometry, I’d like to carry polygon attributes through to left and right-side attributes of each new polyline. For example, if my input polygons were countries of the world, I’d like my output polylines to be borders with each attributed with the country on each side. e.g. Left: France, Right: Germany. I’ve got the polylines geometry coming out of the TopologyBuilder perfectly, but not so lucky on the attributes. I get _left_face and _right_face attributes coming out, but these edge IDs don’t seem to mean anything. They don’t relate to any input attributes, nor are the polygon table row id. I’ve also tried “Generate List From Input Faces”, defined a list name, Selected Attributes, and my

is there a way to convert mxd to cad? including all the symbology?

I have gps points that indicate the speed of a car, I want to sum them around 50 meters averages them. which transformer offers and how it would be worth usingThanks in advance

I am building a vehicle location tracking dataset where I want to keep a history of vehicle locations for future analysis. I am using the ChangeDetector to compare the values in two tables based on a field called [device]. I want to compare the [device] in table 1 with the most recent [device] in table 2 and if there has been a change, 'insert' those values from table 1 into table 2. So where [device] is in table 2 multiple times, I want to compare only the most recent record of the [device] details. When running the ChangeDetector, i have noticed that everything in the Deleted output seems to be the older duplicates. This moves me to my question. Does ChangeDetector just look for the first match for the value and move the others to the Deleted port? Does ChangeDetector use the timestamp field that I have to automa

Is it possible to add transparency styling to DWG output via FME? There doesn't seem to be an option in the DWG styler. If there is an appropriate field in the autocad format attributes i can overwrite this value but I can't see anything relating to transparency.

Is there a possibility to extract only the walls and the roof out of the dae-file ... I do not need steps and all the small stuff..... thx

Hello, I try to create resource inside my Ckan session with the CkanConnector and it doesn't work ><All is good with the dataset creation but when i try this for the resource creationwith url is an attribute with url like https://entrepot.metropolegrenoble.fr/opendata/200040715-MET/ESPNAT_PAT_ARBORE_TOUS/json/PATRIMOINE_ARBORE_EPSG4326.jsonand for dataset the id of the dataset i've got this :HTTP 400: "Requ\\u00eate incorrecte - Erreur JSON : Error decoding JSON data. Error: JSONDecodeError('Expecting value: line 1 column 1 (char 0)',) JSON data extracted from the request: 'url=

I get data via API in a JSON format. The values from "Points" need to be stored in seperate attributes. I managed to do so with JSON Fragmenter (json["points"][*]). With list indexer I can then store each index (0 & 1) to an attribute. But I can not transform then this attribute with DateTimeConverter.  In the log I saw, that the list structure still exists in my dataset. I also found this information in the Feature Information (see screenshot).  How can I actually transform the list into a proper attribute?  JSON Structure: {  ...  "name" : "xy",  "modified" : "2022-02-16T10:16:53.066Z",  "points" : [   [ 1642633200000, 123.99 ], String replacer Output vs. Feature Information:

Hi all, I am designing an automated proces to transform a File Geodatabase into a GML that is validated by an XSD. The validation fails, because the gml_id is part of the geometry trait of the feature, where this shouldn't be the case. When temporarily turning the validate output parameter off, the result looks like this: The red line in the picture above indicates the gml_id I'm talking about. For the XSD validation to work, the gml_id in the geometry needs to be removed. When checking the attributes of the point feature, I see that the gml_id clearly is a geometry trait of this feature. See the picture below: Wit

I am trying to use the BIM360 Docs Connector transformer and it is throwing an error related to a Python library. The error is "No module named 'fmepy_autodesk_bim360docs'". I had originally setup a custom Python interpreter environment using Anaconda so I originally thought it might be that. However, I changed the environment back in FME to Python 3.X (I tried 3.6, 3.7, and 3.8) but no luck. I did check the FME python install location for this file with no luck. Has anyone seen this before?

Hi everyone, I have a question about my thesis.I have a point layer witch including data about the traffic(speed, cars number ect..). And I have a road layer. I don’t know how to connect the the point layer to the line as the closest segment of the line get the datas from the closest pont…I have gps points that indicate the speed of a car, I want to sum them around 50 meters averages them. which transformer offers and how it would be worth usingThanks in advance

Hi, I think I found a super obscure bug in StringSearcher. In my workspace I want to use Regex queries based on different conditions, e.g. if a string matches RegEx A use RegEx B in StringSearcher. This logic does work in general but for one specific query I get the Error:  "Expression Evaluation Failure: 'This FME edition does not recognize the `' function." Oddly the query works fine when I test it in the RegEx Editor. It also works if I don't use a condition or if I use a different query inside the condition. Is this a bug or am I missing something? Attached an example workspace that illustrates the issue. Thank you for your help! 

Hi everyone, is there a way to parse input in text user parameter before running a Serverapp? Let's say I only want to accept letters (A-Z,a-z) as input in text parameter and notify the user immediately if any number (0-9) is used.  I'm cerain that this check can be done at workspace excecution, but that would already be to late as all the given values for user parameters can't be kept and must be re-entered at a necessary rerun. Thanks for your answers!

I think I've used QGIS to its limits and as far as I know ArcGIS don't have any tool different that might be of help for me. Since I've heard about it a a lot yet never used it, I thought FME might have more options to do what I need. If I can do what I've got in my mind I am going to purchase the required license. Basically I've got a very large and complex polygon road network and my main target is to divide those polygons into smaller polygons with almost equal lengths. Also divide them vertically with a centreline if the width of the polygon is above a certain length. But complexity makes things really difficult. In two separate questions, more details on this issue are available on gis stackexchange. 

I have a set of labelpoints that I want to flip to make it readable from a viewpoint from the side in 3D. Is there a transformer that does the trick? Thanks

Hello,This is my first use of the Writer with Oracle, I only used SQLExecutor before.  The problem is, all features are stored correctly, but I cannot get the Writer to store the geometry - it just remains empty.  First I put the name of the table and have specified the spatial column like this:Secondly I basically enumerate all columns:It works, but no geometries are being stored in the "AREA" column. All features come with geometry, I see them cached in the Inspector.  Thanks for any suggestions!   

Hi! I'm validating the quality of the CityGML and CityJSON building datasets. I'm wondering what is the real difference between all self-intersection rules implemented in the FME's GeometryValidator. So shortly: Is the rule Self-Intersection in 2D same as the Self-Intersection under the OGC Valid and OGC Simple?  I think I understand the difference between Ring Self-Intersection, Surface Self-Intersect and Shells Intersect at least. Still, I would be grateful for proper definitions of all these errors. The document of GeometryValidator is a little bit unclear in the case of these "sub-errors". Thank you a lot!

Hello, i have a point cloud data file in e57 format and i plan to reduce it by transform PointCloudSimplifier. There is my workspace.And it appears that warning "The workspace may run slower because features are being recorded on all output ports". The data is very large, more than 100GB, so i wish it cloud be processed faster.​I'm not exactly sure what "recorded on all output ports" means, what should i do? Do i need to add a transform like AttributeManager between the Reader and PointCloudSimplifier or something else?Thank you in advance!

I'm trying to convert a 0/1 value in CSV file to a kleenean value in smallworld. With the AttributeBooleanConverter I get this error:Smallworld Translator Error: Failed to convert string No for field Business to a truth value With an AttributeMapper I get this:Smallworld Translator Error: Failed to convert string 1 for field Business to a truth value What is weird with the AttributeMapper , I have the new attribute mapped to the field for Smallworld and the "Business" field should not even be considered. What am I doing wrong? 

When using SQL Executor or SQL Creator with a PostGIS reader on our Postgres datawarehouse I run into problems with spatial queries.Example given this query:select     table1.name  , table2.whatever  , table1.geometryfrom table1join table2 on ST_Intersects(table1.geometry, table2.geometry)this works only if the two tables are of a different geometry type (e.g. Polygons and Points). If they are both Polygons, FME does not recognise the geometry anymore. The geometry field from the output features does have content but when connected to a GeometryFilter the type is 'Null'. There is a workaround, when using a 'with' statement, like so:with polygons as   ( select * from table1 )select     polygons.name  , table2.whatever  , polygons.geometryfrom polygonsjoin table2 on ST_Intersects (polygons.geometry, table2.geometry Then, FME d

Hello,I would like to +1 a value into a field using the Counter Transformer and although the expression I have used works in the evaluator I keep getting a rejected output with INVALID_PARAMETER_COUNT_START.The output from the SQL Creator Transformer seems to output the correct number.Can you tell me what I'm missing? Thank you.

We noticed that a password was visible in the log file of FME Desktop. Is this normal? We still looking if this is also the case for FME Server. We think this is a security issue. See attachment for an example. We changed the password in PASWOORD.  http://www.safe.com/support

I am currently converting DGN to SV G so that they can be used in ESRI ArcGISPro based Runtime Content. The DGN s that I am converting can be successfully viewed in a web browser, however once they are imported to ArcGISPro the text is not recognized. I was able to determine that ArcPro must have a ttf reference. I am not concerned with retaining the the current shx "font". I just want to overwrite that attribute with a font that is stock to the the Windows Library. I am an FME beginner and cant even expose the shx reference in the writer. Any assistance would be great.

I'm using the JSONFragmenter to choose a segment of a JSON file and am trying to expose the values from this segment as attributes. However, the JSONFragmenter just returns the values as separate objects, and the attributes are empty. I've tried without the "[*]" at the end of the JSON query, yielding just one object but still empty attributes. I've also tried using the JSONflattener on this segment and on the full JSON string, but it does not seem to do anything. It just returns the same attributes as on the input straight through. The parameters of the JSONFragmenter: The segment og JSON looks like this:{ "id": "8a463f67-99c2-4f6b-8703-d154de3dd7ef", "vejnavn": "Tietgensvej", "adresseringsvejnavn": "Tietgensvej",
