In 7.26.0 "make_bb" command-name and command-usage changed, but there are no OBVIOUS documents that alert to the new usage (or that remove reference to the old command). I finally figured out the new usage from the unit/regression tests for MGED in the source-code. (long story short, make_bb <bb obj name> <obj of interest> is now replaced with bb -c <bb obj name> <obj of interest>... while bb <object name> is now a shortcut for what was previously much longer: make_bb <bb obj name> <obj of interest>; l <bb obj name; kill <bb obj name>
Acceptance Criteria (recommended):
Update BRLCAD wiki pages on MGED commands
Update MGED quick-start PDF (https://brlcad.org/w/images/5/52/MGED_Quick_Reference_Card.pdf)
Reason, potential value:
My MGED scripts stopped working, I spent time assuming my environment didn't like the compile binary release that I downloaded, so I wasted time compiling myself from SVN sources... only to find that make_bb had been deprecated (from the 7.26.0 release notes), but then had no mention in any available documentation (or at least those that come up on Google searches, from the BRLCAD home page).
New functionality won't be used if users are unaware.
