Is there a way to see only Nth level related tables to a given table?

by Jan 9, 2016

I have a data model with 70+ tables, and all of them have some number of relationships to each other. In order to view / manage these well, I need to be able to select a single table and view only those tables with a direct relationship (1st level), otherwise it's too difficult to understand how it relates to others due to the large number of intersecting lines. Ideally I could choose whether to include 2nd level (tables that relate to the first level related tables), 3rd level, and so on, but at least have a 1st level.

I don't see a way to do this, unless I'm missing it. While star schemas are a bit easier to do this by having a separate sheet for each fact table and it's corresponding dimension tables, this isn't possible with the very normalized / transactional model that I need to use ADS for.
