Hi, [quote user="hoang sang nguyen"]So if I want to create additional columns in the DATA attribute to it in Brower must do like?[/quote] A note which I think can help you to understand Bentley Map concepts: What you mentioned as "table" in your picture is not database table, so to think in terms "add a column to database" can leads to a confusion. The displayed grid is a kind of summary of data received from all elements representing the same feature. The data can come from different sources: DGN file itseld, external relation database or external spatial database. If you imported your data directly to DGN file as demonstrated in Jerry's tutorial, all data are in DGN file (which is typical XFM technology feature), but there is no database table inside DGN. The data are attached directly to elements in a proper structure, so to "add a column" would require to change this data structure at all element instances, which cannot be done by a user. If you choose a way through Geospatial Administrator, to add new property (column) to a particular feature is easier, because it can be done in GSA as described by Dan. With regards, Jan
