I see some CAD files where house polygons, road lines, cells have attribute data when you list the properties command in autocad. Anyone knows how to add these data? House would have names, etc roads will road names,
The only way I am familiar with is using either GIS for AutoCAD or AutoCAD Map
It would depend. If you are truly looking at attributed data, then you would need to define attributed blocks and enter the information as you insert the blocks.
I don't think you are looking at attributed blocks. I believe the information came from a shapefile. You can import a shapefile as regular Autocad entities using the mapimport command. After selecting the shapefile, one of the columns is for Data. By default this is set to , but setting it to create object data will include the GIS attributes. The entities created will have the extended attributes from the shapefile. I believe this is what you are looking at.

Just tried this - PERFECT! Thank you for that. I have dealt a lot with CAD to GIS and have created shapefiles for others to use, but had always mumbled about how unfriendly CAD was to attributes. It's why I love this site, get to learn more all the time. I won't forget this one.

Keep in mind that if you use Map Object Data, the information is locked up in that product. Nobody with any other DWG product can use (read) that information, they must have Map (or Civil3D).
Thanks guys, just tried the shapefile format & got the attribute data!
