Hi,

I'm new to the FME family and have this question. I have a Civil 3D dwg that we want to transfer to a geodatabase. Transforing the geometry is no problem, but the dwg has extended entity data that I want as attribute fields in the geodatabase.

But, at this time, I can't even find my extended data when inserting the dwg as a reader. I searched this community but so far no luck. I tried the 'AttributeExposer' or ListExploder' transformers, but still didn't get result.

Can someone tell me how to set the parameters so I can read the extended data and will be able to transfer them as attributes in a geodatabase?

Thanks,

Davy

Hi!

I don't have Civil so my answer will be a little approximative.

Maybe the problem come from the reader.

You have to use AutoCAD Civil 3D for the format and on the paramaters have checked "Read extended entity Data as list".

You open the file on the inspector and click on a feature that have extended data and see in which attribute or list the data is stored.

Hi,

Thanks for the answer. I did as you told but that still does not give me any idea on where to find the extended data. Attached you can see the parameters I used to import the civil 3D dwg, and the properties of an object in the data inspector. I have 8 properties mentioning extended data list, but have no clue on how to access the data behind it.

This is how the properties look in Civil 3D. These I want converted to a GIS geodatabase.

Hi!

Maybe try with uncheck "Explode blocks into entities" and "explode MTextentities" and see if extended.data.list give better results on the inspector.

Hi,

 

 

I tried it but still no succes. I can't seem to find out where the attributes are listed, so I can explode them. I'll keep searching ...

You can use the AttributeExposer to expose the extended_data_list{} and then explode it with the ListExploder to get the list elements.

Hello,

i'm facing the same problem with my Civil3D files, I can extract the extended datas from an ACAD file but not from Civil.

Did you finally find a solution or clue for it ?

Regards,

Clem

Any update on this?

Hi @cbalmbra1, @clem_lx, @davygoethals: I'm sorry to hear you're all having issues reading in your extended data into FME. I spoke to a colleague and he mentioned that FME doesn't support Corridors in Civil 3D:

From the screenshots that @davygoethals provided looks like you are dealing with Corridors. @cbalmbra1 and @clem_lx do your datasets contain corridors or one of the unsupported geometries listed here Autodesk AutoCAD Civil 3D?

If you're interested in Civil 3D support for corridors, please up vote this idea Read Civil 3D Corridor and featurelines, and leave a comment to help our developers understand how you hope to leverage it's support in FME. Lastly, if you have any sample data you can share with us, that would also help. Thanks!

Hi, I have the same problem. Tried to find the solution but nothing seem to work. I assign the extended data to features classes file while converting dwg to gdb (conversion to GIS). Any idea how this can be fixed?
