Kathy,
The change should automatically make it into the next release of
AJEM, whenever they pull an updated release of BRL-CAD to include.
You shouldn't need to report it anywhere else unless you find other
issues.
The reid command will probably be useful to you regardless as it can
be used to help create sets of unique region ids. For example, if
you ran reid on a top-level object, that alone would guarantee unique
regionIDs across an entire model .. but they would all be
sequential. :) Normal use is to run reid on a given subassembly
where you're grouping a set of regionIDs together, like having the
fuel system be 6000-7000, so you'd run "reid some_fuel_comb 6000" and
it'd assign region identifiers to all regions under 'some_fuel_comb'
starting with 6000, 6001, 6002, etc.
Cheers!

Do you know if the change you made will automatically go into the
version of BRLCAD that ships with AJEM, or do I need to report this

I am not familiar with reid or remat. I need to ensure unique
regionids and also to generate a list of the regionids and names to
use in my AJEM regions input file and I wrote a script to create
this from the wcodes output.
Thanks,
Kathy

Subject: [brlcad-users] [SPAM] Re: problem with wcodes / rcodes
Kathy,
Are you familiar with the “reid” and “remat” commands in MGED? The
reid command will renumber all regions under a given combination.
It walks the hierarchy and automatically set the region ID on
regions it encounters, which may work even better for you than
“wcodes” or “idents”.
That said, the rcodes/wcodes problem is a “bug”. Not technically a
bug, but it’s a stupid path limitation. There is/was both a limit
on the length of object names as well as a limit on the depth of
paths that those commands will work with. I just applied a change
to those commands that should make the problem go away (should be
in 7.16.6 or later).
I’d encourage you to submit a feature request [1] to have those
sorts of limitations and issues resolved if you know of any others.

I have a large Pro/E model that I used the convertor to create a
brlcad model. This has a very deep hierarchy. I had used xpush to
get individual components instead of instances and needed to
renumber the region ids. I have used wcodes before to create a
list of all components and renumber that file and read back into
mged with rcodes and this has worked successfully in the past with
simpler models.
In this case I have 589 regions. I tried wcodes, on Linux with the
version 7.14.8 that came with AJEM, and got only 544 regions. I
used idents and could get all 589 components. Comparing the 2
outputs, it appears that ones with the longest hierarchy (levels
and length of names, don’t know which is the issue or both). I
reworked the idents output to the wcodes format and renumbered the
idents. I then used rcodes to read it back in. When I checked,
only the 544 parts that could be written with wcodes actually
changed regionid (which makes sense). I had to individually
export (wcode) the problem parts from a lower level in the tree and
fix the regionids and rcode them.
I had also tried this model with the newest brlcad for windows and
neither wcodes or idents extracts the correct number of parts. It
extracted even less parts than the Linux 7.14.8 version.
