Sean,
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 anywhere else?
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.

Cheers!

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.
