I am working on feature and attribute extraction from an AutoCAD Architectural file, namely the extraction of room polygons and their attributes from AEC blocks that represent rooms. I have tried the Civil 3D reader and the reader actually sees the layer with the room AEC blocks and it shows me the available attributes correctly, alas the reader does not return any features. There are no errors, only a lot of warnings about attribute renaming because of scpecial characters.
Has anyone ever succeeded in reading AEC block features and attributes? If so, how did you do it?

Hi
Apologies for the late reply—I was out of the office the past few days.
I tried reading the file you sent using the Civil3D Reader and also found that no features were returned. After further investigation, I found that AecDbSpace
, AecDbDoor
, and AecDbWall
are not currently supported by the Civil3D Reader. As a result, these elements are being skipped in the log file, which explains why no features are returned.
You can view the full list of supported feature types for the Civil3D Reader here: https://docs.safe.com/fme/2025.0/html/FME-Form-Documentation/FME-ReadersWriters/civil3d/Feature_Representation.htm
We're aware of this limitation, and support for AecDbWall
is planned for FME 2025.1. Once it’s released, you’ll be able to download it here: https://fme.safe.com/downloads/
I’ll also pass this along to the development team to highlight the need for broader support!
