Can't open MRF file geometry with FeatureReader

Hello, I am currently trying to open a MRF file with FeatureReader. Usually, when i use FeatureReader, there is a particular output port created on the transformer.In this case, I only have the following output ports :SchemaGenericInitiator.Those outputs do not contain any geometry. When configuring the transformer, I do the following actions :I set the format to "Meta Raster Format (MRF)"I set the dataset I go into "Parameters...", and I set the Feature Type Name to "From format name"I set "Feature Types to read" to "mrf"I set "Features to read" to "Schema and data features"I set "Accumulation mode" to "Only use result".If I run this transformer, it does not fail, but there is no geometry output. If I use a MRF reader it works fine : when opening the inspector, I can see my data and click it. Sadly, this is not the process logic, I must use a FeatureReader. Did I forget to set some parameter ? Ho

How does SolidBuilder transformer work?

Hi, guys.SolidBuilder transformer can construct a solid from surfaces.My question is, how does SolidBuilder transformer work? For example, by inputting 11 faces (as shown below), two small bodies, instead of a large one and a small one, can be built. But how does it implement? (Provided, of course, that the boundary point coordinates of each face can be matched)

An "anything" writer for streaming ?

Hi.I'm looking into the streaming capabilities of FME Server, and is wondering whether a workspace may return more than one type of information as a streaming service.Streaming requires designating one writer in the workspace to be the streaming output, but that also limits the output to a single format. If your workspace is capable of outputting multiple formats, this seems to be a no-go in a streaming context.Does an "anything-writer" exist, that'll just pass anything on, textual or binary, as-is to the output ?Or alternatively, can a workspace switch the streaming target writer on-the-fly based on some condition at runtime ?Cheers.

How much vector tolerance is too much in a Match transformer?

I am using a matcher transformer to match multiple shapes. I have two shapes that are almost a match but are off by .001 of a decimal. In the parameters, I have setting the Vector Tolerance to 1, .01, .001, .00001 and each of those make them a match. We are unsure of how much vector tolerance we should allow because we want these shapes to be as close of a match as possible.

How can I best clean dwg extents before processing?

I'm translating dwgs into Esri file geodatabases. I am aware that i can set a search envelope on the reader but this is only useful if I know the extents of the the dwg. In my case I have 100's of dwgs with different extents and in many cases completely incorrect extents for the projection they are in (they could also be in one of 3 projections).The majority of the data in the dwgs is in the correct spatial location but there are spurious points, lines and polygons way off in areas outside of the project bound. This results in feature classes with inconsistent extents. Is there a way to filter the extent prior to processing so that only features in an extent containing at least 90% of the data is processed? I have started with a few things like counting the features and getting the coords and creating a bounding box....but i was wondering where to go from there? Any suggestions would be most appreciated.

Geometry Validator - Fixing Issue

Hi,I am using FME Desktop 2020.1.0.1 Build 20596 (64bit) and the Geometry Validator seems to not fix the Self Intersecting 2d polyline even though it comes out of the repaired port. Is this a bug or is there anything that I am doing incorrectly or missing a transformer? And what other solution can be done to fix this? Need a little help, please. Thanks Lex

ChangeDetector for 2 colums as unique keys

When doing the comparison, how to specify that my unique keys are going to be 2 columns?  1 column can have the same value in multiple rows, but there can not be two rows with the same value in the two columns.  Example:  This can happen 1 | apple | red |  2 | apple | green |  This can not happen 1 | apple | red | 2 | apple | red |  So in order to check which row has changed and update it or leave It unchanged, I need to specify two unique keys in ChangeDetector.  I have specified the two columns in *Update Detection Key Attributes* but not working as expected  May you advise?  Thanks

How to modify the pre-existing dashboards?

Hey folks, I'm (relatively) new to FME and have had no formal training so I'm flying a little bit in the dark here. I'm curious as to the amount of time our dashboards run on Server and a few of the pre-existing dashboards (AverageRunningTime, DailyTotalRunningTime etc.) look as though they can tell me this, however they only give me data for the past day. Is there a way to modify these dashboard so that I can interrogate or view the data from the past, say, month?Thanks all! Marty

Reading a non Geospatial PDF and Georeferencing it

Hi,I have extracted spatial features from a non Geospatial PDF as a vector file. I am now trying to georeference this in FME and cannot figure out how. Does anyone know how I can georeference the PDF to begin with, in FME? So that I can extract the vector features thereafter...I have tried this already...1) Converted the PDF to a GEOTIFF format2) Georeferenced in ArcGIS using the Georeferencing Toolbar3) Converted back to a PDF 4) Tried to read the features in FME but it did not work. FME was unable to find the spatial features (such as lines, polygons etc.) Any help would be much appreciated! Thanks.

Midpoint between points

Hello, I have a list of points and their geometry:Point IDStreet NameRegion 1Street AA  2Street A A  3Street B A  4Street B A  5Street C B  6Street C B  7Street A C  8Street A C   I would like to create points that are located midway between points that share the same street name and region. In this case, I would like to create a center point between Point 1 & 2, another one between Point 3 & 4, another one between Point 5 & 6, another one between Point 7 & 8. There are always exactly two points sharing the same street name and region, never more or less. What transformers could help me? Thx.

SqlExecutor not respecting attribute encoding ?

Hi.I'm trying to use SqlExecutor to update a table in my MS/SQL database. The table has a Danish character in it's name (Graveforespørgselssvar), but the database has collation Danish_Norwegian_CI_AI, so that's perfectly acceptable.But FME fails, because it mangles the name as UTF-8 (Invalid object name 'dbo.Graveforespørgsselssvar').I then tried to instead add the complete command as an attribute, and use AttributeEncoder to encode this attribute to both "Latin-1 Western European (iso-8859-1)" and "Windows Latin-1 (windows-1252)", both of which do contain all Danish characters, but it still yields the same error.Why do FME insist on sending SQL commands as UTF-8 even though both the attribute encoding and the database collation dictates otherwise ?It looks like a severe bug to me.

SQL executor - Workspace very slow

Hello,I'm using a SQL Executor transformer in my workspace. It is very very very slow (10 features in 10 minutes, I have 200 000 features to read).I have 2 readers and 1 writer from PostgreSQL spatial tables. I created indexes in geom attribute (gist) and primary key (btree) for the 2 readers.The SQL script is :update ref_assainissement.fildo SET nodterrain = 't' FROM ref_assainissement.canaexp WHERE idfildo = idfildoaval OR idfildo = idfildoamont(so very simple)Any idea ? Thank you !

Date Conversion from EXIFF format

Hi Guys, I am reading in JPG's and writing to a TAB file with attributes.I want to convert the EXIFF date format to DD/MM/YYYY with time if possible.The format EXIFF provides is YYYY:MM:DD HH:MM:SS eg 2020:06:03 08:55:21Can this be done in the feature writer? eg changing the value with a @Value(jpeg_exif_datetime,%d/%m/%Y) command is this the right approach?Dave

DWG Writer - Force Output to Autocad Line

HelloI want to write Lines (with 2 points) instead of Polylines, so i use a Chopper to create Lines with 2 Points. But if i use a DWGStyler to set the Linetype all those Lines are written to DWG as Polylines. If i do not use the DWG Styler everything is like i need it. I'm not sure if the DWGStyler is the main reason for this.So i would like to know, is it possible to force the Writer to create Autocad Lines instead of Polylines? The writers Autodesk AutoCAD DWG/DXF and Autodesk AutoCAD RealDWG DWG/DXF create the same result. Thanks

Trace partial road using ShortestPathFinder

Hi, I have a road network and a start and end point on the network. The points are not snapped to the network. I would like to snap the points to the network, then trace the path between the start and end points along the network. I have tried using vertexCreator, followed by Neighborfinder and shortestpathFinder, but no results in the output. Any suggestions and what would be the considerations to improve performance ?
