Extruding lines to faces, the points of each face point in a different order

Hi, I use Extruder to extrude several lines to surface (Parameters: Direction: Vertical). But after extruding, the vertices of each surface point to different orders, some of which are clockwise (the bottom figure) and some of which are counterclockwise (the above figure). If I want to unify the directions of vertices as counterclockwise, how to set?Can anyone help me?

Percentage of common boundaries

Hi all, I have to classify polygons without attribute values, according to neighbouring attribute values. However, this has to be based on the neighbour with the largest shared boundary . A comparisation of shared lengths is necessary when the polygon shares boundaries with two others for example. I have used a geometrycoercer to first make a line of both sets. Then a lineonline overlayer, since I don't think the common segment finder will help me. However, I cannot get to calculate the percentages of different shared boundary so im looking for suggestions. I hope I made myself clear. Thank you in advance!

Where are the attributes created by attributecreator?

I have run attributecreator, creating a field from unique values in a field. I think it worked (no error messages). Where are these attributes? I don't see them. Thank you, Randy McGregorNote: Can't prrovide specifics of the data. Hopefully explaining it will work?

Coordinate system is "IFC_COORDSYS_0" after Coordinate transformation?

Hi,I'm trying to transform IFC data into CityGML data. I use AttributeReprojector to reproject coordinates, and use 3DAffiner to perform a 3D affine transformation on the coordinates. After that, when I use CoordinateSystemExtractor to look at the coordinate system, found that the coordinate system is "IFC_COORDSYS_0", not the one I set, EPSG:31467. Why?A Warning "Coordinate system named IFC_COORDSYS_0 does not exist." appears in the log during running CoordinateSystemExtractor.

Assign Z value for rooflines

Hi, We have as input a shapefile containing roof polygons.We would like to modify certain lines of these polygons such as the gutter and ridge lines.We would like to modify the value of lines which are almost horizontal to make them horizontal ! At the end we should have Z1=Z2, Z3=Z4 and Z5=Z6. Our script is joined. We tried to extract the vertices of the polygons, modify them and then rebuild the roof. It works for simple buildings with 1 roof section but not for more complex buildings with 4 roof sections, for example.Is there anyone who have a solution ? maybe without extraction of the vertex ? Thank you in advance.Victor

Update attributes based on spatial relation

Hi All, I am having grid (red) polygons as shown below and I want to update Grid id to other polygons (black) when it covers maximum portion in that grid. Can any one suggest how it can be achieved in FME. Thanks,Ram.

Writing to SQL using database key

I am parsing an XML and writing the header-content into a table. When inserted to database the inserted row (always 1 row) will be assigned a primary key. The same XML contains a number elements that are written to a separate table in the same database. The two tables are connected by former database-assigned key.How do I add the database-assigned key to the features before writing to the second table? Can I handle it in FME? I tried using a SQLexecutor, but performing a call to get the key seems like a bad idea.Do I have to go to T-SQL and write to both tables in a single SQLexecutor?

How can I add a published parameter that is multiple choice with alias with a tree?

I want to create a published parameter that will give users the option of choosing multiple options from a dropdown/tree list, depending on the category. I could use 'Choice with Alias (Multiple)' and then an AttributeValueMapper, but I'd rather not as the 'Choice (Multiple)' has the ability to 'Use Tree'

2020.1 Release Date?

Hi, is there an official date for the 'launch' of 2020.1 (Server & Desktop) yet please? We're looking to upgrade, but I'm unsure whether, given the timeframes, it's worth aiming for when 2020.1 is released out of Beta?Thanks,Martyn

Find Longest Line Segment after Splitting Line Segment On Polygon Boundary

Hi, I am to perform a spatial join between a line and a polygon. In some cases the line will be crossing polygon boundaries (there are no spaces between polygons). For these cases, I want to split the line, and find out which segment of the line is longer, then assign that polygon's attribute to the original line. I've tried used the LineOnAreaOverlayer to split the lines, then using a Matcher to find 'duplicates' (lines that ended up getting split between polygons), and then the LengthCalculator. So I have something pretty close to the end product. I have a match_id value from the matcher so I know which lines belong to eachother (on top of a GlobalID that I'm using in the matcher). The issue I'm facing with this approach is that I do not know how to split these lines apart, or compare them against each other. Maybe I should use a sorter, then some type of filter to split every one feature into different features?

Dynamic Writer Multiple Errors (Cannot find Schema & Geodatabase Error (-2147219884))

I finally think I have my head wrapped around dynamic writers but I am running to all sorts of errors What I am looking to do is use a NeighborFinder transformer to join admin boundaries to my data while also using the dynamic fields for each feature in a geodatabase.I am having multiple issues when trying to write dynamic dataOne issue I am having is that I am getting a "|Geodatabase Error (-2147219884): The Field already exists." error. I tried to remove/rename ObjectID and Shape fields with no luck.Another version of this workbench and I am getting "Cannot define schema for 'unknown' as the feature does not contain schema information, and schema source is set to 'Schema from Schema Feature'. Please verify writer feature type configuration" errorAnytime I change it back to Manual writer I have no problems writing the features to the geodatabase. I have been stuck on this for a few weeks now, let me know if you have any suggestions. Thanks in adva

Most common network_id from NetworkTopologyCalculator?

I am using NetworkTopologyCalculator to categorise streets by what network they are a part of, with the aim of only keeping the main network and discarding the islands.How do I determine the most common network_id value?And then how to I place that value into an AttributeFilter to only keep those features?

Attribute Header Mapping

I have a number of large CSV's which dont have headers for the collumns. I then have another CSV with the headers / attribute names. I want to be able to map the atribute names from the header csv to the incoming CSV's with the data in? I suspect there is a simple way of doing it but i can't find one. Any help will be appreciated.

DonutBuilder error

Hi.I have a dataset of polygons, which I don't trust entirely. It has a lot of smaller polygons (wind mills?) on top of property polygons.Most small polygons have been cut out of the property polygons, but not all. So I run the data thru the DonutBuilder, just in case.But I've found an error in the output, where a small polygon inside a larger polygon with a cut-out matching the smaller polygon, replaces the former small polygon with a new with the values from the surrounding polygon.I.e., the smaller polygon is inside the outer boundary of the larger polygon, but has already been cut-out of it. In this case a replacement wasn't warranted, but something happened anyway, resulting in the described error.Does DonutBuilder only use "entirely within" the outer boundary for its matching, or ?Cheers.

need to take email addresses from a AGOL table, and add to an existing text file, only if it doesnt already exist within this text file

Hey, So I have an ArcGIS Online Form, users enter an email address.FME periodically checks this AGOL table and grabs the list of email addresses within.What I am trying to do is insert these emails addresses into a local text file, but only if this email address does not already exist within this text file. This text file is simply a list of email addresses, think of it as a single column CSV file.If the email address is already in the text file, FME needs to go off and do other things (that part I have sorted).What is the most efficient way to test if the email address (its just a string) exists in an existing text file?I currently am using a feature joiner to do the test, joined means it already exists, unjoined means they dont already reside in the text file. This does not feel efficient, I am guessing there is a more suitable transformer out there?

Is it possible to create an AutoCAD 3D soild with different coloured surfaces

I've been having some issues with Creating and reading AutoCAD 3D Solid geometries. Through my investigation I have found that the REALDWG writer/reader supports solids the best (ACAD will just read as multi-surface in most cases), however, when it comes to colours/appearances FME is falling short. While I can create a single solid feature with once color (using the default layer color), I am unable to color the surfaces individually which is pretty well supported by a lot of other formats in FME. In addition DWG files which contain solids which have different color surfaces are just read in with all surfaces coloured as the layer color. Has anyone had any luck either creating OR reading solids from AutoCAD witch have different colored surfaces? Here's an example which creates a multi-colored solid box: @daveatsafe or @andreaatsafe perhaps there are some PR's relating to these issues already?

FME Pirate Fun

Ahoy mateys! Today is Talk Like A Pirate Day and so at the risk of getting keelhauled for this, I decided to have some fun with it and build the PirateOnChestOverlayer transformer (available in the Hub).Obviously inspired by the pirate song from Robert Louis Stevenson's Treasure Island :)Fifteen men on a dead man's chest Yo ho ho and a bottle of rumThere's of course Piratespeak log messages, thanks to heavy use of the MessageLogger custom transformer:And the nice thing is that if there's not enough pirates (we need fifteen, according to the song...) it will send out a press gang to round up some more (now if only it could invade other running workspaces and kidnap features from there...). However... if there's too many (we can only put fifteen men on a dead man's chest...) the extras will unfortunately have to walk the plank...Have fun!
