Okay, then you probably don't want xCase. xCase will create diagrams more like VFP, except that the relations run from table to table, rather than from table index to table index. IOW, they're evenly distributed around the edges. xCase also allows subDiagrams if you want to show just a part of the database.

But it isn't particularly hierarchical. Sorry I couldn't help more....
