Import of external data into AutoCAD

[NikWach]

Hello, 

could someone explain me, how I can attach some external data to an AutoCAD object. I found on the internet the object data solution for AutoCAD MAP 3D, but my boss meant, I should find a possibility to import data into AutoCAD without MAP 3D. 

Could you tell me, how it should work/or give me some tutorial links?

With kind regards,

NikWach

Each DBObject in Autocad has an ExtensionDictionary property. You can use this Dictionary to store extended data for each object.

The Dictionary is a DBDictionary. There you can store your data with a unique key and access it later on.

Be aware that if you ATTSYNC a block it erases all those block instances' extended data. See: http://docs.autodesk.com/ACD/2010/ENU/AutoCAD%202010%20User%20Documentation/index.html?url=WS1a91938... and other such friendly URLs.
