Intersecting polygon dataset to keep only parts which don't intersect

Hi,I have two polygon datasets (A and B). Of B I want to keep only the parts of the polygons which are not overlapped by A. Let's call these output features the dataset C.Additionnaly, I'd like to calculate the area of the C polygons. Ideally, I'd need to know the area of each C polygon. I've noticed that AreaCalculator seems to ouput only one single feature...Thanks in advance for your help !

Corner Style of buffered polylines

Hi, I'm applying a simple buffer to some polylines with the End Cap Style None and the Corner Style Arc. I was expecting to get rounded buffers on the inner vertices and none at the endpoints. However, I don't get rounded buffers on any vertice of the line, see screenshot. None of the points of my lines are treated as corners. Am I misunderstanding how this is supposed to work?

CSV reader fail to read negative integer as int. Issues with encoding

I struggle to make FME read csv files with correct encoding and datatype.I receive csv files in UTF-8 that includes non ASCII characters.FME think its win-1252 encoding and this interpret signed integer values like -27 as âˆ’27 and thus make it a character datatype. To fix the encoding i have to add the csv reader to the workbench and then change en Character encoding to UTF-8, then it works. But at that time the datatype is already set and I cannot change the varchar type column to be int32. It cause issues becasue now I cannot write to my database which expect int and not varchar...So how can I change the datatype of multiple fields after the reader has been added to the workbench? Alternatively (and better), define the CSV reader to be using UTF-8 before the CSV file has been scanned for its content

How do I sort a list of features by an attribute value in a PythonCaller?

I'm working with groups of features and I want minimize the number of blocking transformers in my workflow. Right now I'm using a Sorter to sort features in each group and a PythonCaller to make some attribute manipulation and comparison. Both transformers block the flow so I wanted to get rid of the Sorter and do the feature sorting inside the PythonCaller but I don't see how to do it.Once I have the list of features, what should I do to sort them by one or any number of attributes? Thank you! import fmeimport fmeobjects class FeatureProcessor(object): def __init__(self): self.feature_list = [] def input(self, feature): self.feature_list.append(feature) def close(self): pass def process_group(self): for feature in self.feature_list: ## ...

Setting a list of lists as a _list attribute in PythonCaller?

I have a list of lists resembling this structure:sublists = [[1,2,3],[4,5,6],[7,8,9]] When I try to set this "list of lists" into a list attribute I get the following:code - feature.setAttribute('chunkList{}', sublists) error - Python Exception <TypeError>: Could not convert attribute value to a supported attribute type.Traceback (most recent call last): File "<string>", line 95, in inputTypeError: Could not convert attribute value to a supported attribute type.Error encountered while calling method `input'PythonCaller_Get_chunkList (PythonFactory): PythonFactory failed to process feature The goal is to have a list of 1000 unique IDs or less to feed into a readerI do not know how many lists there will be ahead of time so I need to dynamically break out the lists into individual lists of 1000 elements later in the workflow which is why I want 1 list of lists to start with.

Combine single character text features to create words (longer strings)

Hi, I'm trying to read PDFs and it looks like each character of each word is represented as individual features. Each PDF has thousands of these text features that I need to combine to make words. I'm stumped as to how to string these single character text features together to create words. I have attached an example below. Any help would be appreciated. Thanks in advance.

How to generate multiple PDF files from an Oracle database with a common image (logo).

Good morning. I'm writing this question to see if someone can provide a new idea! I saw couple blogs talking about, but without good result.I am trying to generate an atlas, given an Oracle database, of different files, each one with its ID, generating a PDF file for each one.The problem appears when adding a common image, such as a logo. If it comes from a reader, when doing a "fanout" on the writer, how it detects that it does not have an ID generates a file separate from the others, with the common information.After trying with a cloner, feature merger, or adding an attribute that is the path to the image for each record, I cannot get it to be seen (I can show that the path is physically written).Any ideas? Thank you so much!

shortening point lists

Hello. I have a question. In "list_of_fixes" I have a list of track points and some of the tracks have more than 75 points. For tracks that have a higher number of points, I would need to filter and shorten to 75 points. The reduction in the number of points should be from the center to both sides. This means if I have, for example, 81 track points, I will delete 3 points from each end of the list. In the attachment I am sending fmwt, where the list is visible. Some ideas? Thank you very much

DWG with multiparts being split by reader in FME

Hi everyone, I have a dwg with autocad blocks which has several layers of polygons, polylines and annotation. I have a workspace to extract and convert these to shapefiles. The problem I have is that multipart polygons and polylines are being split by the FME reader. When opened with ArcMap or Autodesk TrueView, the multiparts appear correctly. I have tried to play around with the parameters of the dwg reader (entity option/advanced options...but everything I have tried so far has not worked and some of the settings read far fewer components than needed). Anyone have any experience with this? Thanks in advance! :)

Create a chart by group id in a Custom transformer

I have a input data file with a unique ID (BORRHAL_NR) with 2 variables (Date/Granvattenniva). I am using a python caller in a CT to generate a chart with matplotlib. I would like to produce as many charts as unique IDs, and I am using the group by in the custom transformer but even though it produces in this case 4 charts I see that is using all data from all unique IDs in those charts (except for the first one that is actually correct).Any ideas?I am using FME 2022.2.4.

Dynamically setting "Columns" on UPSERT in FeatureWriter to PostgreSQL

Hi, I have a dynamic workspace where I am reading in multiple csv update files for multiple feature types to upsert into our database. I had set the primary key dynamically dependent on the target table in the database. I cannot set a where clause on an UPSERT (which I do use with other feature types that have the ability to do I, U, or D) so went to use the "Row Selection: Columns:" section instead. This parameter does not work in the normal way with attributes. It presumes the selected attribute is the primary key field (no orange left arrow in front of the name), rather than using the value. I tried manually adding @Value(primary_key) (the attribute that stores the primary key column name) in the parameter but the feature writer also presumes it is literal and obviously can't find a column called "@Value(primary_key)" and errors. This is something that I would like to do, and is very much a part of a dynamic workflow. Otherwise I will have to create one dynam

OBJ to GDB and offset to location

Hi there, I have a whole lot of OBJ's of course they don't have any coordinate system, but they are tiled, so the first is 0,0 the second is 100,0 etc. I want to move these obj's around the world, I thought to just use an offsetter, but it scales the OBJ down.In ArcGIS PRO I can just move this over the map, and I hoped that the offsetter did something similar.I guess this has something to do with the world not being flat, but is there an easy fix for this, or even a hard fix. I really don't care which coordinate system, I can always reproject it. Thanks :-)

Appending one geodatabase feature class with another.

Hi, I'm having trouble appending one feature from a geodatabase, with another feature from a different geodatabase. To put it simply I want to turn 2 features into 1 feature. I'm using the terminology ("append") from this article, so I hope I've phrased this question correctly Combining Multiple Streams of Data (Append vs. Merge or Join) (safe.com). The schema is the same, I've attached a .gdb with the example data within it. Note: this is part of a much larger question, of how to append two separate .gdbs together (both with the same schema), but I figured I'd start on this mirco level and expand what I can learn from this forum to solve the bigger task at hand. I've attached a pic of the my attempt (this mess may or may not help) Thanks for your assistance

Create Line from IFC data

I have an IFC file containing information about sewage pipes. In theory, it should contain two types of object classes (with geometry), namely IfcDistributionChamberElement (Manhole) and IfcPipeSegment (pipe). These classes use their subclasses as connectors, namely IfcDistributionPort (at each object node). Finally, these IfcDistributionPorts should be connected to each other using a relationship class called IfcRelConnectsPorts. In IfcDistributionPort have attribute named FlowDirection with value (source or sink) like in or out. The attached image shows a depiction of the connection.My question is how to create a shapefile containing line features to represent the flow direction so that when I upload the shapefile into QGIS, I can use arrow symbols on the lines.
