Convert dwg to shape by colors

Sometimes when I do a transformation from dwg to shape everything is included in 1 polyline (text, pipes, arrows) and when I look at it in inspektion mode I see that the dwg is splitting the lines by color, how do i do the transformation with a separation by color or adding the color value inside the whole polyline Sorry if my vocabulary is wrong

FME Form (desktop) best practices and style

Hi,I was wondering if there are some best practices and or style guides / examples on for workspaces. Some questions that I have about this (besides the obvious: avoid crossing as much as possible, annotation, clear transformer names etc) Like is there an agreed style for public and private parameters (casing, under scores, ...)Is there an advise on how many transformers can be put in the main part and how many in a custom transformer?How many custom transformers can be nested into each other or is it advised to not do this to deep (performance impact)Any other good to implement styles?

Difference between SPHERICAL_MERCATOR AND SPHERICAL_MERCATOR_0

I am Featurejoining the output from a change detector that compares an original layer from ArcGIS Online to a revised layer from my Geodatabase.    Note:  The AGOL layer was originally published from ArcGIS Pro from the coordinate system WGS 1984 Web Mercator (auxiliary sphere) .The Featurejoiner transformer rejects the features saying: “Coordinate system does not match first feature's coordinate system”Similar to the issue as seen in https://community.safe.com/topic/show?tid=20659&fid=8When I inspect the original and revised features, my features on AGOL have “SPHERICAL_MERCATOR” and my revised features have “SPHERICAL_MERCATOR_0”In  my workspace, my revised features are reprojected with ESRIReporojector to WGS_1984_Web_Mercator_Auxiliary_Sphere before entering the change detector. They then show a Coord system of  “SPHERICAL_MERCATOR_0”.    FYI  The ESRIProjector does display a warning saying “2.1_EsriReprojector: Ignoring input feature coordinate system `_MGA2020-54_FME_0'.

Migrating data from Oracle to SQL

I'm migrating spatial data from AutoCAD (hosted in an Oracle database) to a SQL Server(ESRI geodatabase). I want to automatically extract domain values from Oracle lookup tables and populate them as domains in the SQL Server (EGDB) without using ESRI tools (like ArcGIS or ArcPy). Is there a way to automate this process, and what would be the recommended approach?

How to automatically expose attributes

Hello,I have a question regarding the implementation of dynamic attributes.I created a flow to turn a single attribute into text for the actual values of the column and row of an attribute; Following the pattern below: Original AttributeGoalAfter achieving this, the biggest problem is that these 'dynamic' name attributes come as unexposed attributes.Unexposed AttributesI could simply place an AttributeExposer and resolve this case, but the problem is that the flow will run in several different scenarios, and the values (A, B, C, F) will never be the same; they can vary to anything (G, H, T, Z, B, A, or K, LL, BN, XS, D).Therefore, I need the exposer to work automatically as well, but I couldn't make it receive @value(list_name); it literally exposes the value '@value(list_name)' as if it were an attribute with the name of the code. Thank you for your assistance!Best regards,

Trying to deal with Waze malformed GeoJSON feed due to encoding. Handling line geometry.

Ok so I have read that the Waze JSON feed is not formed correctly which stops FME from natively reading the GeoJSON with a reader. You have to use a httpcaller with the Accept-Encoding heading parameter. So I got the translation started but I have hit a snag with the line geometry for the JAMS and IRREGULARLITIES feature categories. Here is our waze feed if anyone can get it to work properly with a reader instaed of a http caller.https://www.waze.com/partnerhub-api/waze-feed-access-token/8065da30-c46e-4dee-937a-68b8dac4d2a0?format=1 I have attached a sample json txt file of our feed. The issue im having is I have paired the line features down to {"x":-96.637385,"y":32.846625}{"x":-96.637275,"y":32.846417}{"x":-96.636865,"y":32.846035}{"x":-96.636524,"y":32.845655}{"x":-96.636179,"y":32.845214}{"x":-96.635502,"y":32.843905}{"x":-96.635225,"y":32.

How to read a JSON file from waze

Data Virtualisation Transformers

*Aka Data Virtualization Transformers, but with the french touchSince I’ve been publishing a bunch of Data Virtualization custom transformers lately, I figured it was time to make a post about them—what they do and how to use them.FME Flow’s recent update introduced a cool new feature: Data Virtualization.https://community.safe.com/product-updates/introducing-fme-data-virtualization-38066?tid=38066&postid=86#post86This feature lets you build your own APIs using FME workbenches.To make that work, your features need to include certain attributes required by the Data Virtualization writer, such as: response.status_code response.body.content response.body.content_type response.body.content_file_path response.headers{}.name response.headers{}.value Data Virtualization Writer  After manually setting these with an AttributeCreator a few times, I thought: why not create a tool to make this easier?So I made the DataVirtualizationResponseSetter !DataVirtualizationResponseSetterThis

FME Form Ubuntu 22.04 synology file server permission problem

Hi,We are trying to use a FileCopy Transformer to transfer files from one location to our server (synology) / other computers (other computer).If we do it in Ubuntu GUI / SystemCaller command it works perfectly.But the file copy transformer always give error messages as we don’t have sufficient permission. Even if I put our NAS credential in the transformer (with a featureWriter), it give the error messages. The files are created in the server but there’s no content inside.Does somones already experienced it ?Thank’sSam

Black screen FME Form 2023 and FME Form 2024

Hello everyone,At our organization we work on a virtual machine. When you log on into a virtual machine, you share the virtual machine with other users. Since a few weeks we encounter sometimes black screens when trying to use FME form 2023 or FME form 2024. I googled and the problem is quite similar to Known Issue: FME Workbench 2023 Opens as a Blank Window on a Virtual Machine – FME Support Center, instead it's a black screen. The article mentions about OpenGL versions, however the specs for all our virtual machines should be the same, so I think the cause is different.When you encounter the black screen, you can only hover over the black screen and can't do much else. When you close FME Form and try to open a new FME Form sesssion, you still get a black screen. The only workaround is to log off and log into a new virtual machine where this problem doesn't occur. We already did some troubleshooting and we know one thing for sureIt's possible that fme form 2023/2024 initially worked f

Attribute Creator - Adjacent Feature not populating more than 1 record

Hi, I am using the attribute creator to populate a new field. I want to fill in the blank rows with the previous master property number from the master prop no field. I have enabled the adjacent features but no matter what I try it still only populates just the 1 record after a value and not all the blanks. I thought I would only need 1 based on what I’ve found on the forums.What am I doing wrong here?I also tried to do that same thing via the attribute manager but get the same result.The end result would also have row 3 (FME row id not the xlsx one) with ‘932590’ and row 6 with ‘933123’ and rows 9-11 with ‘933796’ etc with the number of blank rows varying from 1 to potentially hundreds.The settings I have for the transformers are below.I am using FME 2022.2. Thank you! Belinda

Fill in adjacent empty values in table is not working as I expect?

I am trying to fill in the rows of my table with the previous values. I saw this thread and I am following the instructions but for some reason I am only getting the first empty row to be filled but not any subsequent rows.  I tried to change the Subsequent Features to another value other than 0 and even tried to change the number of Prior Features but I always get the same results.I am on FME Form 2024.2.0.0 if that helps. Any suggestions as to what I am doing wrong?

Help me sort out the PythonCaller syntax from where AI left me to fend for myself

I don’t have an programming background, so please bear with me. I need to find out the circular standard deviation of the rotation attributes from a set of features in degrees.The built in AI in the PythonCaller has taken me as far as the code below. I have tried many different prompts, they use somewhat different methods to do the calculations, but all throw errors about missing methods or incorrect classes. It seems that the AI is unable to initialize the script “The FME way”, or I have not figured out the correct prompt.What do I need to ad to the script in order to get the below working? My desired output is the circular_standard_deviation as a new attribute.Another nooby question, what should I write in the box: Class to process features? import mathimport numpy as np# Function to calculate circular standard deviationdef circular_standard_deviation(angles_deg): angles_rad = np.deg2rad(angles_deg) sin_sum = np.sum(np.sin(angles_rad)) cos_sum = np.sum(np.cos(angles_rad))

Emailer referencing the workspace result

Hello, so we have now switched from Server to Flow and all is good and great except from one bit, and that is there have been made some changes between these versions that have made my emailer workarounds from Server useless.So what we did before is that we just set up the Emailer in the workspaces and sent automatic answers in the ‘Body’ section of the Emailer such as:p>Hello Colleague</p><p>Here is your GeoJson to DWG/Shapefile datapackage:<a href="$(FME_SERVER_DEST_DIR)">Click me to download</a></p>Where the ‘$(FME_SERVER_DEST_DIR)’ was the download link for the result and it worked very well.But now on Flow it doesnt work, the email sends and all but there is no value being fed into the ‘a href’ so now download hyperlink for the message.What has changed here, is it only the value for the URL and if so what value should I be referring to now to get the result data on flow downloadable?If this has now been made very different then what should I be doi
