AutoCAD Map has three options for bringing attribute data in:
1. Ignore it (the default)
2. As 'Object Data'
3. As 'SQL Table'
'Object data' is an internal format stored in the drawing file. 'SQL Table'
leaves database management up to you (like if you want to use Oracle,
Access, dBase, etc.).
'Object Data' is easiest, so start with that. Start the import process. In
the second dialog box titled 'Import Data Options' select "Map Data
Elements to Object Data", then click the 'Data' button to the right and
give the object data table a name. And finish the import process.
I am assuming the when you say "Grid" you are importing polygons, if I'm
wrong, the following may not make much sense. AutoCAD Map & MapInfo handle
polygons (and topology in general) quite differently. You can't click on a
polygon in AutoCAD Map to get attribute data, the attribute data is
attached to a centriod object, usually an AutoCAD point. If you don't see
point objects at the centriod of your polygons, change your point style
(Format > Point Style) and do a regen. Now use Object Data > Edit Object
Data click on a centriod, and there's your data.
