Hi Bob.

>But i doesn't seem to do anything. If a change the table comments in xcase to correct a mispelling, then run xcas2dbc, the comments in SDT Explorer have not changed. If I bring up Explorer and delete a table from the list, then run xcas2dbc, the table does not get added back from the xcase model.

Are you using the xCase update function to update the physical tables and DBC? If not, SDT won't see the changes you made since some of them are stored in the DBC (such as table comments).
