I would like to separate roof from 3D feature, I have building footrprint, DEM, LAS file.

Hello! I could make a 3D buildings with simple roof form, I got SurfaceNormal Z, so I could separate flat form roof. But I have a building with complex roof. So I want to separate the building from certain Z height, above it, it is roof and under it, it is body of the building. Do you have any Idea to get it?

Can the attribute value mapper transformer map multiple values in one record?

Hi, I am working on translating data from numbers to phrases. I know using the String Replacer and Attribute Value Mapper is the best for this, but I am having issues when trying to map more than one value to one field.  An example would be the reason_of_given_set has multiple values, I need these values to populate with given phrases, each number represents a phrase. I provided the parameters of the transformer I am using below. I also tried creating 14 different string replacers to represent each number and each time the output shows blank at the attributes with multiple values. I am probably using the Attribute Value Mapper transformer incorrectly and its not designed to do this, or I have the parameters set incorrectly. Does anyone know how I can fix this?

Text string from file using FeatureReader Transformer

I have a "Directory and File Pathnames" reader that gives me a list of text files in a Windows folder. I want to pass those folder and filenames to a FeatureReader transformer and be able to read the text lines from them as output for further processing, but I can't seem to get anything out of the FeatureReader other than the results of the Directory and File Pathnames that go into it. How do I get the contents of the text files out?

Please find the screenshot. Could you please help me in this regard. Same issue was posted 6 years back https://community.safe.com/s/question/0D54Q000080hfTrSAI/citygml-generation Wall not render properly in FME inspector

DWG Writer - Dimension Text Rotation

The documentation for autocad_dimension features says that you can use an attribute "autocad_text_rotation" to rotate the text of a dimension.See autocad_dimensionHowever, I haven't succeeded in rotating the dimension text yet.I use "autocad_dimension_type" = autocad_aligned Any ideas?

Excel Writer with a template: conserve columns positions like the template

Hi, I'm trying to write an XLS file based on a template (according to this help), with complete rewriting of the data (Overwrite Existing File = Yes) and I can't find a way to keep the order of the columns according to the template in the output XLS and not in the order in which FME processes the attributes. For example, I would like that if I invert 2 columns in the template, it also inverts it in the output xls, without setting this with an attribute manager. Did I miss a parameter in the xls output that would allow this or is there another method.Thanks a lot in advance for your answers and best regards. Antonin

Overwriting an individual layer in a hosted feature class in AGOL

We have a client that has a unique need and I'm wondering if it's even possible in FME. There goal is to have a csv or table that contains a dataset name, itemID, and layerID. They also have a GDB file containing the datasets. The would like to have a function to cycle through their csv table, and overwrite an individual layer in an AGOL hosted feature class. The caveat is this hosted feature class may contain many layers and as far as I know you can't update just one layer. We have been racking our brain and FME seems like it may be our last hope. Here's the short version of the workflowRead update table -> Read GDB -> Update Hosted Feature Service Layer Any advice would be appreciated,Chad

How do I set the isNullable (Allow NULL) property for an attribute when writing to a feature class in an Esri SDE database?

In an Esri SDE database, fields (attributes) have a property setting of isNullable (Allow NULL). This property determines if the field allows null values or not. I want to be able to set this property in FME when I create a new feature class. Is there a way to set this property with the Esri Geodatabase SDE writer? See screenshot below to see how to set the setting in ArcGIS Pro.

Dynamic Workbench

i have two geodatabases. geodatabase 1 containing all lookup tables. One lookup table is source_table in which there is a column named "source_table_name" is added. Based on the values in "source_table_name " I want to select the feature class from geodatabase 2. I am getting output but its routing through generic port of the FeatureReader so no schema is being added. Can anyone help me solve this issue.

GML to any other format

Hi! I have a gml file that i have downloaded from the statistical bureau of sweden. This is the data source: https://share.scb.se/OV0105/Xml/PD/pd_befolkningsfordelning_totalbefolkning_nt.xml It is in GML format and the data is structured in 10km squares. However, I can't seem to be able to convert it to any other format. The geometry im getting is just a bounding box for the entire dataset, not the specific 10km squares. I have found very limited resources to help with this problem online. The final destination should be in an enterprise geodatabase.  Has anyone else had trouble with this? Thankful for any help.  /Alex

Accessing usr/bin/ (gdal) from SystemCaller?

I am trying to run a Shell Script from the System Caller but am running into issues when accessing the various gdal programs that are called from within the script. These are stored away in usr/bin/ and "globally" accessible through the PATH file. The folder where the command is run is generated by FME in earlier steps, so its not as straight forward as copying the gdal files to the folder. Is there some workaround to get this functioning?

Finding related points.

We have some Annotation points all in one feature class. We are looking to find duplicated annotation text that are close to each other. We used the NeighbourFinder and attached the attributes from the neighbouring annotation to the base annotation. This allows us to see that, for example, record OD=1 is close to OD=2. Then a Test Filter is used to check if the TextString is the same on the base annotation when compared to the neighbour.  From the results of the TestFilter we have a list of annotations that can be reviewed as it looks like they are close to each other and have the same text string (which may not be needed).  So, for an example, say there are 100 annotation points that come out of the TestFilter. For each of these points, one of the other points in that selection of 100 points is the point it is related to/neighbouring. So, we don't actually need a list of all 100 points, just 1 of the points from each relationship, resulting in 50 points.  Currently we are

In other words, I need to create a point event layer.As you can imagine, the accidents don't happen at an exact vertex of the road.Can FME create that point event layer?I've tried using the Snipper transformer, but I'm not getting the results I want.
