Reading DWG with 2 transformers

At this moment I received a DWG drawing with both Extended and Object data. To convert this data I first have to read with:

Autodesk AutoCAD Civil 3D

then read with

Autodesk AutoCAD Map 3D Object Data

and merge all features on the autocad_entity_handle

 

Am I doing something wrong or is this the only way to get both attributes?

Is it possible build a transformer that uses both reading engines because I think that would make the reader faster than current.

Hello, @jkr_wrk.

Thanks for your question. As of now, that is the only way.

The Map Object data is built on the Autodesk-supplied RealDWG reader while the Civil 3D reader is built on the ODA-supplied reader. So, they are using two completely different libraries to read the same file.

We are looking into if this current process can be tweaked/enhanced: (FMEENGINE-82673).
