FME does not read in AutoCAD mass elements

Hello everyone,

 

I noticed that FME does not read the AutoCAD 3D element types

- mass element 

- mass group (which is composed from mass elements)

at all. On the other hand, 3d solids are read in. Below is an example of this.

 

Is there any way to read in mass elements from AutoCAD files with FME (e.g. by suitable parameter settings on the reader)? Alternatively, is there any way that with FME, I can detect if there are mass elements in an AutoCAD file (a simple yes/no would be sufficient for me)?

 

Here is the example: 

I have some DWG file containing four 3D objects, one mass element, one mass group and two 3D solids, one of which is the mass group converted to a 3D solid:

01_AutoCAD exampleWhen I now read this DWG file into FME (Autodesk AutoCAD DWG/DXF reader with standard parameters), only the two 3D solids are available to me as FME features, but neither mass group nor mass element:

02_FME example I attached the DWG file to this post.

Yeah looks like that geometry type isn't supported yet

You can see warnings in the log file when reading:

 

"AutoCAD Reader: Found proxy entity of type 'AecDbMassElem' but proxy graphics were unavailable for this entity. Skipping entity"

 

 

If you use the RealDWG reader it will at least create a feature with Null geoemtry for it as an autocad_proxy type.

 

If you read by geometry mode it comes is as a new unsupported layer type

Hi @virtualcitymatt​,

 

thank you very much for your response.

This is really helpful, so I can at least detect if there might be any mass elements in the DWG files.

 

Best regards to Berlin!
