Dia3d?

[Christopher Nelson <chris nelson 1022 gmail com>]

I love Dia but I'm looking for a tool which lets me create "3d"
diagrams which I can drill down into.

Say I have a top-level data flow diagram where A sends X to B which
sends Y to C.  I want to be able to drill down into B, see X coming in
and Y going out and be able to create B1, B2, B3, etc. as subtasks of
B, interconnect them, hook X and Y up to two of them and save it.

Or maybe I start by creating a bunch of processes in a complex diagram
then I can multi-select some and say "demote these to detail of a
single process" and have them replaced by a single process on the
current drawing but drilling down later would reveal the detail (while
hiding detail on the top level).

I could see the same being useful for network diagrams.  Your top
level might be data centers with trunks or "the internet" between
them, drilling down could show rooms or racks and their
interconnections, drilling down into a rack would show servers or
switches, etc.

I've Googled around a bit and not found anything.  Does anyone here
know of anything like that?  Does it make sense as a direction for a
fork of Dia?
