If you scale the tree larger you will be able to see all of the text. There is
a scale slider on the perfly interface. I do like your idea of color coding
though, in inventor when you interactively edit the database using gview they
have different symbols for different types of nodes. The symbolology is defined
in the inventor mentor so if you have read the book you get it right away.
