Transformers

Hello, the objective of the workbench is to cut objects in order of priority according to the values of the attributes. The priority has to be fixed automatically.I first generate a table that looks like this:The objective is to autmacitally generate the order of clipping in a table : I don't know how to solve this problem, can anybody help me?Thank youRonan

I have a scenario like this:where I have a series of points, each surrounded by lines. Each line is split at every intersection and we can assume that all possible polygons would be closed. The lines, unfortunately, contain no useful attribute information to assist in this selection process What I'm looking for is a good method to reliably select line features that can form a polygon, that surrounds the point, with the shortest perimeter. For example in the diagram below the orange point would have the orange lines selected and the same for the purple.

Hello I'm running an FME workbench that will basically clip the Oracle Spatial data and transform into DWG format. I've used clipper to clip the larger boundary to smaller areas and running the transformation on individual smaller areas. FME Desktop 2016 is throwing Insufficient memory available when i'm running on 32GB RAM and 64 bit PC. I'm happy to attach the FME workbench if needed. Any help would be much appreciated. please find the attached log

Is there a easy way to do that in FME?Thats how i did it:now i wonder if there is a easier solution.

I have an attribute in a .gdb containing dates in the format (yyyy) in a geodatabase in short integer which I need to change to an actual date attribute in the format (dd-mm-yyyy) with the date being january 1st for all. Is this possible? /Rasmus

Greetings friends. Tell me if FME has the ability to change the texture size in FBS files containing building models while maintaining UVM coordinates. If this is possible, tell me with the help of which translators this can be implemented

I have an requirement where to write an xml file with around 12MB, which is taking almost 30 mins in a 16GB ram server. Is there any alternatives

Is there a way to enable feature caching between sessions, so that the workspace doesn't need to be re-run after closing Workbench? Thank you.TylerFME Workbench 2020.2.1.0 Win64

Hello, I am working with a Civil 3D 2019 file with FME verison 2018 that I want to convert the dynamic blocks as points to a GIS layer. I can see in the Civil 3D file a field name Visibility1 that has text of what type of water fitting it is. i.e. TEE, BEND, VALVE etc. (see image) I would like to "expose" this attribute to use in the final GIS point layer as an attribute. I looked online for solution. I tried using the attribute exposer to get autocad_entity_visibility, autocad_text_string, autocad_entity_visibility and autocad_visible_attributes{} butI don't see any text. I have exploded and not exploded block entities. I checked and unchecked read visible attributes as text entities. I am sure that there is a solution, but haven't found it yet.Thank you for your responses and help. 

I want to create a new attribute from a regex pattern found in another existing attribute. If no pattern found then default to static value. Say for example, attribute bID has values 1<a>4, 44<a>, 98. My new attribute would be code1 would have values a, a, d. The regex finds the 'a' and 'd' is the default if no 'a' is found. I have played around with a series of transformers, but my solutions are clunky. Can someone propose an efficient solution? I'm struggling a bit with how to use the text editor to return a found regex pattern. Still learning! Also, I want to stick with implementing regex code because my actual problem may have a more complex regex pattern.Thank you,TylerFME2020.2.1.0 Win64

I'm attempting to confirm that a set of GeoJSON area features are geometrically identical to a Shapefile produced from the same source. Of the 19k features, less than 400 come out as Unchanged, with the rest going to Inserted AND Deleted. I've set match Geometry to 2D and turned ON Lenient Geometry Matching. When I write the same GeoJSON out to Shapefile, the resulting Shapefile gets all of its features routed to Unchanged under the same settings.  Any ideas as to why I'm seeing this behavior?

New for FME 2021.0 is Group-By functionality on the FeatureWriter transformer. Group based transformers process data simultaneously based on data groupings. When Group-By Processing is enabled, the user can choose which attribute to use, which divides the data into groups. Additionally, if your data is pre-sorted into groups before entering the transformer, selecting “Process When Groups Change” can speed up the transformation as the transformer isn’t waiting for all of the data before sending the group of data out. In addition, when the groups change in this mode, the current writer will be closed and all its data will be written out before the next feature arrives.  By adding this functionality to the FeatureWriter, data can be forced to be written out chunks at a time by using attribute values to define groups, instead of waiting for the entire transformation to end. This will avoid running out of resources such as file handles or memory in certain scenarios. One example is streamin

Hey, How do you split two differents feature type, like point and polygone, that went into a Tester together, back to being independant again. Thanks, Ian 

Hi, I have a set of polygons (representing the street blocks) from which I was able to create centroids. I would like to create a grid from those points, meaning that points would represent grid intersections. Have already tried with triangulation but had no success.If it is helpful I can try and upload a sample. I would really appreciate any suggestion. Thank you.  Edit:I believe I need to explain a bit more. In the current approach I am creating a "grid" based on the street centerlines and merge them with Neighbourhood Aggregator to 800x800m cells. The problem is that at the end grid borders are always on the centerlines (one side of the street is in one cell, where the other side of the street is in neighbouring cell). I would like to now try a different approach, where the grid borders would connect centroids of those blocks, this for example would be the output (red lines). Ideally, they would have a more rectangular shape, but not exclusively, it could also contain squa

Hi all, Feel like a regular here now, but after the success of my last question about keeping the lowest date in a series of entries, it appears that only some of these entries have values in. For example the reference field and date field will always have a value in, but the others? Not so much. Here's an example (attached). I've tried to use Aggregators and AttributeManagers to varying levels of success, which have ultimately caused more issues...but I wondered if there was a way of keeping the data from the populated rows and putting them into the others for that specific Reference number? Hopefully the attached screenshot will show what I mean. Apologies for the blanking out of data as it's confidential, but I've been wondering about this all day. It seems so simple, yet...not. Thank you

Hello, this topic is based on this initial post from me:https://community.safe.com/s/question/0D54Q000080hM3SSAU/what-are-the-fme-best-practices-for-modularization?t=1609774258752 However, the question is now a bit different. Therefore, I will open up a new topic. Goal: I would like to develop a linked custom transformerIssue: If the custom transformer has some sort of complexity, I have problems debugging it, since things like “feature caching run” is not available there.Used FME Desktop Version: 2020.1.3.0 (Build 20632) I tried 3 possible solutions, but I have some issues with all of them. Maybe you can help me out finding the “right way” to do it. Possible solution 1: Convert the linked custom transformer into an embedded one, develop inside the embedded custom transformer and then export it back into a linked custom transformer.Possible solution 2: Copy the content of the linked custom transformer into a new workspace, develop inside this new workspace and copy it after the develop

I'm trying to extract all of the data from a table that lives on a webpage along with the hyperlinks that are embedded inside of one of the columns. The HTML table reader is only able to return the data that is displayed on the webpage, not the hyperlinks that are present. On the flip side, I can only get the HTMLExtractor transformer to collect the first record in the table. Attached is my workbench... what can I do to collect all of the records in the table?

Hi all,I'm trying to keep the highest date in a range, and each of these has the same reference number. For example - "Reference Number 1 has 8 dates and we need to keep the highest date for Reference 1", but repeat a few thousand times. I've had a method which worked before using Adjacent Attributes and sorting, but it doesn't seem to be working here. The dates are input in the %Y%m%d format (ie. 20120301) which I had hoped would make sorting easier. I didn't know, after a long search and trying methods out, if anyone had any pointers on how to achieve this highest date business? Thank you

Hi Everyone, I have problem with exporting textured OBJ file to other 3D files. Only geometry was exported. It is even possible?  

Hello & Happy New Year Whilst testing this transformer I realised that if I set it to:Download "As File"Download To Folder "Intentionally set to wrong location"  Then the invalid setting is not rejected nor the cog changing its colour to red.Is this by design? If I, of course, amend the ObjectID then the feature will be rejected.I also set the target folder (wrong location) as an attribute and same result ThanksSameer

I'm trying to write a a few 3D buffered lines into an IFC file. Buffering the lines to solids works fine, resulting in IFMEMultiSurface geometries which in itself consist of a good amount of IFMEFace geometries. When writing to IFC, I'm creating these features:1 IfcSite1 IfcProject1 PropertySetDefinition700 IfcProxy (my buffered lines) In the log I get the following warning while no features are written: IFC: Unable to write a geometry of type 'IFMEFace' with representation identifier 'Body'... Last line repeated 65059 times ... Any help would be appreciated. I can't find any documentation on 'representation identifiers' and how they influence writing IFMEFace geometries to IFC. FME 2020.1.2 b20620

I've had some issues regarding this Transformer: Dissolver.Using a dataset of polygons, after being worked, it is assumed that there are present a bunch of geo-issues as Gaps, Overlaps...  Firstly, for GAPs, as my First option, I start dissolving the entire dataset to then extract "holes" or gaps with the transformer: DonutHoleExtractor. Here is my input: Consequently, and as I expected, all Holes were extracted and solved within the rest of the FME workbench, until I double-checked on the final output, where I mimic same transformer on Final Output, and surprisingly I got new Holes: Example: (I know, there are a bunch of holes... :_( )From the first Dissolver output, I'd get the Green ones, and with last final check (remember, same Dissolver transformer), I get the red ones, green ones were solved:Also, as you can appreciate, from the very beginning, there were green and red ones already on the dataset. The Dissolver parameters: My Second option was to try, on the sa
