IFC 3D Room Clip and Buffer

I have IFC file with 3D Room and Excel Records with XYZ and i am trying to clip the XYZ coordinates that totally fall or touch the boundaries of 3D Room.  I would like to confirm is that,  i am following the right steps in Workbench ? I would like to ADD 10 cm buffer to 3D rooms, so that i don’t miss any XYZ records, so not sure what is equivalent value as there is UNIT in buffer :( Also i would like the EDGES to be SHARP after applying buffer not sure how to do  PS: Attached is FME Workbench for further reference, as its does work if anyone would like to refer as well. But open for any enhancement as well.

Feature Class to Database field mapping

Completely new to fme and trying to find my way.I have a GIS feature class titled wMeter.  I want to take fields from this feature class and load the data into an existing excel database (provided by others). I added the feature class as a reader and the existing excel database as a writer and field matched which fields from the wMeter feature class I want to go into which fields in the database. I used an AttributeKeeper transformer to remove the unneeded fields from the feature class and it seemed to work at first however each time I ran the form it would append the data in the database. I changed the Writer Mode to Update so now it appears that I am getting the data 2X in my results.

SQL Query

I am attempting to get the value of a date field from a subset of data tables in an Enterprise geodatabase.  I have narrowed down the list of tables with the required attribute from the SDE_column_registry and I only want to query those data tables for the value of that date field.I have attached two screenshots showing the inner join and rejected output and part of the translation.log.  Perhaps I am formulating my query incorrectly. I am only concerned with getting the value of the date field from 133 data tables that have the attribute.Please help.SheilaCounty of Kern, CA

Extract area overlap of two polygon boundaries

Hello,I have two polygon datasets: folios and townlands(see image below). For the most part, the folios(grey outline) are nested neatly within the townlands dataset(red outline) so the outer folio boundaries are shared with the townlands’ boundaries. I would like to extract the areas where these two datasets’ polygon boundaries cross...i.e. where they are not nested neatly. Most of these will be slivers.  SpatialRelator(and Tester) helps to extract the offending folios using the Spatial Predicates Test: "Requestor OGC-Overlaps Supplier" however the output is the entire folio polygons(not overlapping area) as SpatialRelator does not edit the input dataset. I am unsure as to what to do next, I would like to automate this process in FME Server if possible so having one workflow would be useful.

Choice of triangulation transformer

I’m doing a project where I have to generate and compare multiple DTM TIN-models. In regards to this, I wonder: Is there a difference between TINGenerator and Surfacemodeller in regards to how the triangulation algorithms work?How does the triangulation algorithm(s) work, in more depth than that it is delaunay triangulation?​​​​​​​Are there any other transformers/methods to produce TINs in FME?

Write multiple geometry types as geopackage

Hello all,When trying to write my data as a geopackage I get the following warnings (see attached).In the reader I have to specify what geometry type I want to use but I can only select one, which results in some features being excluded.I have read a thing about the dynamic writer but that one is giving me errors.Using the GeometryFilter the only type I get is ‘area’ so it doesn't seem to make a distinction between those.Is there a way to write these different geometry types in one Geopackage layer? I am using version 2020.0

Problem with ListExploder with Version FME Desktop 2024.0 (build 24187)

Hi,Have a workbench that I have been using for a while in previous version (2023).This is to convert data with attachments from ArcGIS online to a FGDB.I use a ListExploder for this, I don't get an error message but also no objects.When I use the workbench again in the old version, everything works fine again.The problem occurs when a space is used in the naming of the layer and/or feature class. Does anyone know about this problem? Any solution would be helpful. Gerard

I want to convert the obj model with map coordinates to the glb model with local coordinates (0,0,0).

I'm converting an obj file to local coordinates, glb.Running one obj file in FME will take you to the desired local coordinates.But when I run thousands of obj files in FME, they don't move to local coordinates (0,0,0).I want to move thousands of obj files all to (0,0,0) at once.For reference, I activated move to local coordinate.

IF loop in FME with creator (i++)

​Hello guys, Damjan here,i have problems with my FME process so i need your help.  Task:I have 1 dwg file with 6 polylines (3 pairs), each pair must go to PROCES (process makes a polyline between 1 pair, that's fine all works), then process must save this polyline in dwg and go to start for next pair.Shema: FME:DWG GRT: Each polyline has an attribute id which represent pairs (for example: 2 polylines (grt_dt & grt_lt) have the same id which means they are 1 pair), the second attribute is Description (DET_OPIS): grt_dt = right polyline, grt_lt = left polyline.  I add Creator to make counter, with the Attribute manager making the same attribute like in dwg (GRT), and then connect to tester. My idea is that the tester test if value of counter equals to id. If its true, then go to process, when process finish, save to dwg format and then go to start for next pair.  Problem:I have problem in tester cause i dont know how to setup tester to make him work. If anyone know how to fix that or

Calculating vertical error of TIN from point cloud

I want to compare different methods of generating TIN-models. To assess the quality of each model, I want to calculate the vertical distance between each point in the input point cloud and the generated TIN in order to later calculate for example the RMSE. Any tips on an approach?

FTPCaller and Emailer question

I am using FTPCaller. If I add the Emailer to the rejected port will it send me an email if the output gets kicked to the rejected port? I would have the Emailer already configured to send me an email. I want to double check with the Community since my workbench will stop running if the FTPCaller output is rejected. Here is a screenshot of a mock up workspace (note I have not set up the transformer parameters yet hence you see the red gear icons.) Not shown below, I know it will send me an email if the FTPCaller output is sent to Output.

Performance ECW reader

I'm trying to read a (big?) ecw file (EPSG 28992, 173 Mb) using FME 2020.1.0.1.This is very slow (> 10 minutes), QGIS displays the same file in a matter of seconds. I'm wondering if I'm missing some reader parameters that might speed up the process. I do need best resolution though...

FME equivalent of ArcGIS Tabulate Areas?

Dear all, I’m fairly new to FME but currently I’m quite impressed by the software :). My question is rather simple: is there an equivalent in FME of the Tabulate Areas function of ArcGIS Pro: Tabulate Area (Spatial Analyst)—ArcGIS Pro | DocumentationI have two datasets:The cadastral parcels of Wallonia in polygon format ; A land cover classification (TIFF raster) with 20+ classes.I would like to calculate for each polygonal entity the proportion of land cover classes.The result should look like this:ID | LC1 | LC2 | LC3 | … | LC201 | 10% | 0 | 0 |25 | … | 02 | …3 | … Many thanks in advance for your feedback :)

Expose attributes in XMLFlattener based on list

I am getting features in through a WFS and pump the resulting XML structures through an XMLFlattener.The Elements to Match are ‘grouped’ by an attribute value and thereby dynamic.What I cannot make dynamic are the Attributes to Expose. I can either write them myself, or import them, but how can I get e.g. a list to work there, or the value of an attribute?Best thing would be the option of a conditional value… 😉
