Hello,

Can CADImport.net read "Extended Entity Data"?
If yes :
- how it is link with entity?
- which class represent this data
- can you post a simple sample?

Best regards, yannick.

Hello!

CAD Import .NET reads "Extended Entity Data" only for AutoCAD entities accordingly to "DXF Reference" documentation. Do you mean some exact extended data for some entities?

Sergey,

Yes, i mean "Extended Entity Data" for entities.
I need to read "Extended Entity Data" of all entities of a layer of a dwg file.

Yannick,

Accordingly to AutoCAD DXF Reference documentation there is an APPID table which contains user-supplied (or application-supplied) application name (for extended data). These applications can add theirs data to ExData.

AutoCAD uses “ACAD” name to define data which is not documented through the main group codes. CAD Import .NET can read this AutoCAD data. CAD Import .NET may not read ExData of the other applications.

Thus first of all it is necessary to specify what exactly ExData you need to get.

Hi

I want to export "Extended Entity Data" for individual polyline objects, in DXF format.

I have found my way through to export the 'normal' properties like coordinates, color, width etc. but I have more information attached to each object which I would like to add to the exported data.

I cannot find any methods to define such extended attributes for a polyline ( the DXF group 1000 ones ) - is there anyone out there who can tell be if it is possible and hopefully also how ?

I'm using C#

Hello Jan.
Unfortunately CAD Import .NET doesn't support "Extended Data" export.
