Fanout and zip outcome with FeatureWriter

Hi!I'm changing my classic readers and writers to use FeatureReader and FeatureWriter transfomers.One of those writers is a INSPIRE GML that creates as many gml as distintc values has a field. And then, all of them are compressed in a zip file:I don't know how to do the same with the FeatureWirter transformer. There I only have one text box for the Dataset.Is there a way to achieve this with the FeatureWriter?Thanks for any help!I'm using FME Desktop 2017.

Specifying Features to Read

I am needing to read a DWG and read only the features that meet a regular expression, and wasn't sure if that would be possible. The features have a dynamic suffix to them, but I need to match only part of the name, then read those specific features into the workspace.Example:Read only the features that contain "BOUNDARY".DWG features: BOUNDARY 321, BOUNDARY 123Thanks for any help.

Pulling my hair trying to figure out what's going on with FME and encoding in Python.

Hi ! Something seems very odd to me using python from inside fme...Note I'm french, so I handle data with a lot off accented characters. Using FME 2016 on windows server, with Python 2.7, I faced a LOT of characters encoding issues, and am still facing some puzzling situations. for what I understood : 1) The usual mentions # -*- coding : utf8 -*- or likes, (that every text editor would use to encode the script as utf8) are ignored by FME's Python Callers' text editor, I finally figured out that the code itself is encoded by fme using windows encoding (windows-1252) in my case.That alone could be source of errors, if the python interpreter reads # -*- coding : utf8 -*- someVariable = u'Projet Terminé'While the code is encoded as windows-1252 the interpreter will try to use an utf8 codex to decode it and get the unicode value for its variable, resulting in an error.This has a sample solution, use # -*- coding : windows-1252 -*- at the start of each script, to be sure that the interpret

Group Line based on spatial location and limit it by max number of ID in individual group

Hi All,I have line network where in i want to create a group of line based on there spatial location. But in this i want to limit the number of line in each group if the line number exceed than the defined value (i am using feature_ID for defining my line criterion )then it should go for regrouping.For this i have used the buffering and then i am using a tester to check the number of feature in each group. I am able to separate the feature but i am not sure how i can re-group those feature in new group based on my criterion.

Execution from command line sometimes doesn't write data to log file

I have been running my workspace (which unfortunately I cannot easily share) that uses a number of PythonCallers which each writes to the log file via the FMEObjects calls. What I have found is that when running the workspace from the GUI all the log messages are written to the log file. But when running the workspace from the command line I have found that some installations of FME will log all the details while others will not. Is there some configuration file or command line option that would force FME to record all log messages to the log file?

Can you submit a case?

My submission of a case has been rejected and this message page appeared, even though I surely filled out all required fields and also the attached file size was very small. Could you please check if the system works fine?

Checking point or vertexes on a line have sequential attribute values

Hi, I'm trying to check if power lines have been connected together with sequential pylon IDs (VOIDENTIFI). Below you can see the attributes for one of these power lines and that the pylon ID is sequential (apart from the first two "0" & "1" points for some reason, so we'll ignore this issue or just start counting at "1" maybe).Ignoring this minor issue my goal here is to flag up if the pylon id is not + or - one, from the adjoining point on the line. The list below is correct but if one of the pylons had been had been skipped then I would like to flag up this point or line. I am unsure how to deal with attribute values that are changing and each line is a different length too.Any pointers on where to go with this would be greatly appreciated.AdrianAttributes of interest for one polyline example: VOIDENTIFI{0}.VOIDENTIFI (encoded: fme-system) KZ0329H083EVOIDENTIFI{1}.VOIDENTIFI (encoded: fme-system) KZ0329H083EVOIDENTIFI{2}.VOIDENTIFI (encoded:

trouble writing 3d extruded building to DXF

HiI want to write a 3D layer to DXF. The layer is extruded buildings from a 2D building layer, using an Extruder. When I write the output to DXF, it appears as a 3D object, but with triangles - screenshot attached.Looking at the fme attributes, fme_type is fme_surface rather than solid, and fme_type is fme_aggregate. My understanding from reading some other posts is that I need the features to be solids not surfaces. Using the Geometry Coercer has no impact, it does not change it to a solid. And according to the help for the GeoemtryCoercer this is likely correct ("If you try to set the feature's geometry to fme_brep_solid and the geometry of the feature is not a composite surface or multi-surface or extrusion or box or csg solid, then the feature's geometry will be unchanged.").Any ideas on how I set the feature to a solid? or what I need to set any autocad settings to - another post mentioned setting autocad_solid3d, but didn't give a value to set it to.Thanks f

How to create textured multipatch from textured CityGML?

I can't find any options to specify anything texture-related. Saving to mulitpatch through a workspace ends up with blank geometries, saving to multipatch in the inspector does the same. I found a sample workspace* but this again ignores the textures. Is this not possible with FME?* https://hub.safe.com/templates/citygml-to-esri-file-geodatabase

Best way to find a change of sign

I have some ordered features that contain a value, and I need to identify the inflection points, ie the feature where the sign (+/-) of the attribute value changes compared to the previous feature ex. features have values [2,3,1,-2,-1,1,3] the inflection points would be features 3 and 5 For added entertainment there is another attribute containing a common ID, and I need to break on that value.

Validating AutoCAD version

I have seen that the version of AutoCAD a dwg file was saved in can be found as per this link, however I'm after ideas for a good, quick way to validate this - e.g. version must be 2007 or newer. I am using the RealDWG reader, and the workspace will have to work on FME Server.I have tried exposing the autocad_version format attribute, but in the file I am testing no value comes through for this. I do note that FME was able to do a version check when reading as shown in the log, in which case this file was found to be AutoCAD 2007.I have thought to perhaps save the file to a temp location, read it back in with a text reader and find the version through that but I'm hopeful of a slightly tidier solution within the workspace.Also been asked to validate dimension type, but again autocad_dimension_type is missing. Perhaps it's just my source data letting me down!

Points to Raster cell value assignment

Hi! I'm trying to create a raster based on high density point features (bathymetry data) from ArcSDE. The thing is that I want to control which features enters the NumericRasterrizer/RasterDEMGenerator (or some other suitable transformer) and gets assigned a cell value. The problem is that the point data is much denser than what I want the resolution of the raster to be. In this case I want FME to pick the point feature with the minimum z-value of all the in-going point features and assign it to the cell and ignore the others. Much like you have in ArcMap where you can can choose the "Cell assignment type" in the "Point to Raster" tool. Is there a way in FME to solve this?Thanks!

convert one point into multipoint

I have a dataset containing different points. To insert them into my postGIS database I need to convert each point into multipoint (but each multipoint is only containing one point)I may not change the geometry-type in postGIS, so I just need to store each point as a multipoint...I already did some tests with the aggregator and geometrycoercer, but can't figure out how to change the geometry from point into multipoint. maybe a bit of a silly question, but I just can't figure out how to do this :(thanks for helping me!

How to separate parallel lines to create more space (for a map)

Dear FME community,I have a shapefile with lines that are partially parallel. We want to create a map for 1:50.000 and there the parallel lines are too close together to distinguish them :-) Is there an easy way in FME to separate the lines, i.e. to make more space between them?I think the Offsetter makes offsets for all the lines, but I only need to change the parallel one's. And each parallel line in opposite direction.Kind regards and many thanksThomas

dangle nodes and pseudonodes

I am a newbie to FME. I need to create nodes from a road network shapefile. Initially in ESRI, I created a network dataset and subsequently nodes. The resulting dataset had pseudo-nodes and dangle nodes along edges and at ends of segments. This wasn’t what I wanted. How do you distinguish between intersection and overpasses? How can I use FME to generate nodes only at intersections? I will appreciate it if you can send me a workflow.

Identify non exact overlapping polygons?

Hi,I am currently working on a project where I am trying to identify non exact overlapping polygons. For example the polygons in the first image below would be highlighted as they overlap but not exactly. In the second image the polygons would be ignored as they are an exact overlap of each other:I tried using the matcher to remove the exact copies followed by the spatialrelator but this seemed to return polygons which don't overlap or intersect with any other polygons.If anyone could provide any advice on the best way of doing this that would be great. If there is any further information I can provide please let me know.Thanks for your help.Thanks,Charlie

How to split supersmall intersected parts of line

This kind of line intersections are in source data and can be visible in ArcGIS only at very large scale (1:1 or closer) and Intersector doesnt split them. There are no option to set tolerance in Geometry validator or Intersector, nor other transformers, that are involved.

Is it possible to copy/paste conditional statements in AttributeManager?

Is it possible to copy/paste conditional statements in AttributeManager? I have three attributes that I want to calculate values for in AttributeManager. All three are based on the same conditional statement. Is it possible to set up the conditional statement for one attribute and then copy/paste it into the other attributes (under Attribute Value)? The conditional statement has six conditions (A or B or C or D or E or F) and I might change it later so it would be easier and reduce mistakes to be able to copy/paste rather than recreate/change it three times.
