Transformers

Greetings for the day, I am new with the coding world. I am using Python and IfcOpenShell to work on IFC files. I want to use a command ifc.open but it is not working. I am using Python 2.7. Please help me with this issue. Thank you

 Hi, I'm trying to read in a CSV file that has no header information. Additionally the data is spread around several columns rather than in a single line. Looks like the first row is junk.The second is the site name.The third is the site number.Fourth is pressure informationFifth is the date and start time of the data6 onwards is the dataHow do I first create a schema that FME uses before it tries to open the file? I attach a file as an example.Thank you.

Hello,I have multiple segments line for which I would like to add a measure on the starting/ending of each segment. In other words, I would like to create a "fake" LRS  where the measure will be computed from some attributes of the feature.I thinking of using python with this logic def addMeasure(feature                coord = feature.getAllCoordinates()    n=len(coord)    mfr=feature.getAttribute('MEASURE_TO')    mto=feature.getAttribute('MEASURE_FROM')             if mfr!=None and str(mfr)!='':        setMeasure(coord[0], mfr)                setMeasure(coord[n-1], mfr    feature.addCoordinates(coord)where setMeasure should be a python version of the measureSetter Transformer.How should I proceed?

Hi all   I am using FME to convert a ESRI File GDB containing building polygons to AutoCAD DWG. Really simple styling and the resulting file looks fine except for one thing - when opening the DWG it opens at THE SAME location as the template file. The template file is overidding the new data. This is not great if I have data in say Manchester and the template file is in London.   This is a process I need to batch repeat for multiple locations are the UK - but the resulting DWG will always startup in the London location despite there being no data there. I have not had this problem before with a similar task.   (1) Is there a format setting I can utilise to tell the DWG to zoom to data extent on startup?   (2) The only styling information I am taking from the Template file is "Visual style - Realistic with no isolines" (creating 3D Polygons) is it possible to set this in FME without the need for a template file.   This is a really simple issue that I can't seem to fix and

Something I encountered recently: When I send multiple features into a FeatureReader, I only get one SchemaFeature. I expected one SchemaFeature per initiator feature.As I needed a SchemaFeature per Initiator, I merged them using a FeatureMerger after the FeatureReader. But I keep wondering if this is how it is supposed to work?Thanks!

When the FeatureReader outputs a SchemaFeature, the attribute handling differs from Features. For example, I use the Prefix Initiatior option a lot, but it does not work for SchemaFeatures.Is this how it should work? Thanks.

Hello,How can I replace a line with its corresponding points with a python caller?I tried the following code but it is not working.import fmeimport fmeobjectsclass pointCreate(object):    def __init__(self):        pass            def input(self,feature):        if feature.hasGeometry():            coord = feature.getAllCoordinates()            cpt = len(coord)            #coordSys = feature.getCoordSys()                        for cpt in range(0,len(coord)):                feature.setAttribute('X_e', coord[cpt][0])                feature.setAttribute('Y_e', coord[cpt][1])                feature.setGeometry(fmeobjects.FMEPoint([float(coord[cpt][0]), float(coord[cpt][1])]))                #feature.setCoordSys(coordSys)                self.pyoutput(feature)                     def close(self):        pass  

Hi, I'm new to the FME world, and have a question that probably has a super obvious answer to anyone with experience with FME. SQL is rather new to me too. I've got an SQLCreator with the following SQL Script running in it, against an Oracle Spatial Object database.I know I need to enter something in the 'attributes to expose box', but I can't for the life of me work out what it needs to be.FME_SQL_DELIMITER /DECLARE GLASSHOUSEAR number;BEGIN    select count (*) INTO GLASSHOUSEAR from GLASSHOUSE_AR;END;/DECLARE RAILWAYSTATIONPT number;BEGIN    select count (*) INTO RAILWAYSTATIONPT from RAILWAYSTATION_PT;END;/DECLARE MARINEWATERAR number;BEGIN    select count (*) INTO MARINEWATERAR from MARINEWATER_AR;END;/ When I use the following in the SQL script, all I need in the 'attribute to expose' is 'count(*)

Hi,I know that FME has WebMapTiler as one of transformer utilities and it's good for creating image tiles in 2d web map applications.However, as 3d web gis is evolving and as there is more possibilities to build nice 3d web gis applications using libraries like CesiumJS and similair, i wonder if there is any plan in near future to enable tiling of 3d datasets using FME. For example, that you have 3d mesh and you want to create quantized-mesh tiles using some FME Transformer ?  I know it's probably not so easy to implement at the moment but I would like to know if it's something that is on TODO list or not?  Thank you and kind regardsIvan

I am hoping someone can point out if FME has a "Save a Copy" feature for manually saving a back up copy of a workbench. I searched here in the community and elsewhere and found references to backup functions for FME Server Workspaces, but nothing specific to the desktop workbench. Perhaps this function is called something else in FME speak so here's a description of my workflow:When developing a workbench I periodically save a back-up, currently when I do this I go File > "Save As" and save the file with a sequential suffix like [filename]_ii.fmw then a while later I'll save another copy as [filename]_iii.fmw and later [filename]_iiii.fmw. Sometimes I'll tag a date on the end. As the project nears completion and its down to the final tweaks I find that I'm working out of a "master" .fmw that is simply [filename].fmw and when I save a back up I use "Save As", add the sequential suffix, then do "Save As&

Hi.What is the optimal way to merge several pictures from different WMS servers on top of each other ?All pictures are transparent PNGs except the bottom layer, which is JPEG.All pictures have the exact same size and map view.I'm using ImageFetcher to get the WMS images.Cheers.

Hi all, I have a set attributes and some of them consist of day time.And I would like to catch those that have such information. Examples:- BUS LANE 6-9A EXC SAT-SUN-HOL - MON-FRI 8A-8P SAT - SHUTTLE BUS ONLY 6A-8P MON-FRCan I catch those with StringSearcher? How should be the reqular experission for that? Thanks in advance.

Hi I am using FME 2018.1 desktop and server and trying to publish a workspace.Today, this comes up with User is not AuthorisedThe specified user credentials were not authorized to perform this action. Ensure with your server administrator that your user credentials are authorized to perform this action. I can login with same credentials to FME Server web user interface. Also I have been able to publish to FME server before today. I am using the admin credentials to publish (which has fmeadmin, fmesuperuser access)Any suggestion what could have changed and how to investigate this issue?

Hello everyone,I have center line data and I have created two offseted lines by using OffsetCurveGenerator. How can i cleaned the lines after the intersection of the two lines? By using Topologoy Builder, I have splitted them so those are individual lines. But I could not find way to delete them.Blue lines represents the lines that I would like to remove.

Hi, is it possible to hide the systemcaller cmd line when using it inside a workspace being run from workspace runner. At the moment my screen looks like this and it is a touch annoying!Thank you   

I have two tables, one which hold records of planning cases that need to be monitored (Table A) and another which is the master list of all planning cases (Table B). In Table B, there is a string field called 'Proposal' which contains a description that may include the reference number of one of the cases in Table A (there may in fact be many records that relate to a case in the Table A).I would like select all of the records in Table B that contain the case reference from Table A in the Proposal field. I don't think I can use the feature merger as the information in Table B is contained within a Proposal field and is not in a field itself. I thought about trying to extract the case number from the Proposal field but, whilst it is normally at the end of the string, this is not always the case. It is also not a standard length.Can anyone think of a different transformer I could use to achieve this?

Hi FME ninjas,I'm using the HTTPCaller to call a website containing multiple URLs in its HTML. I'm trying to extract all the URLs that have below format, based on these I'd like to create and attribute (URL) that shows all unique urls as features. What I have: What I want:  Does this make any sense ;-) ?  Thanks,Eduard

I created a workbench which reads an ECW (which I call current imagery). I then read GeoTIFFs (which I call new imagery), mosaic the rasters together and then write to a new ECW, which becomes the new current imagery ECW.I've noticed contrast changes in locations which are not being overwritten each time I've added new imagery and recreated the ECW.What could be happening here?The below image is a location which hasn't been overwritten by new imagery. I've run the new workbench 4 times now and you can see its getting darker each time.  More notes: I have done some further analysis.By using the PointOnRasterValueExtractor I was able to get the RGB band values at a location before the mosaic and after the mosaic.Before the mosaic: 82,92,82 After the mosaic: 9

Many years ago, the swedish National Land Survey issued topographical maps on CD-rom, using a self invented raster format known as RIK. Lately, these maps have been published as Open data. But this resurrected format is not known to FME.There is open source code to read this format, and it is supported in GDAL. Thus, it can be read and displayed in Qgis but not (as far as I have found) read with FME. What would it take to create a custom reader in FME using information in the links below? Apparently, the 'custom reader' ability in FME desktop needs a supported format to begin with.https://sourceforge.net/projects/trikpanel/https://github.com/OSGeo/gdal/tree/ab9e80368ef662712c963191fd86fde2c5b75600/gdal/frmts/rik
