Summary: Ray-trace after region edit fails

Initial Comment:
When using 7.14.8 in Windows, the raytrace functions fail after editing a solid or region. The raytracer (rt, nirt) works perfectly fine up until the point something is edited, whether it be a solid or booleans within a region. After that, a "Raytrace Failed" message appears when trying an "rt" or an "nirt" command. This has occurred on several of our machines which probably means its not computer specific or path related. The only fix is to shut down the model and re-open which is quite annoying.  Has anyone else seen this error? I sometimes get frustrated and revert back to 7.12.6.

Message:
I did the sample case you suggested and I cannot duplicate the problem. Now
I know how the wife feels when she tries to explain whats wrong with the
car. I also placed the sphere in a region, displayed the region, edited the
sphere and pressed accept. Raytraced fine. I then made another sphere and
subtracted it from the first in the same region. Raytraced fine.

I can't seem to duplicate the problem with these simple cases which leads
me to believe that the problem is more complex than my initial explanation.
When it happens again I will take a screen shot of the error and explain
what I was doing when the error occurred.

Reopening this issue since it's apparently still broken as of 7.18.0

Bob, how exactly are you editing a solid or region?  Command-line
commands? Which ones exactly?  Using the GUI?  Does this work for you:

Z
make sph sph
B sph
rt
sed sph
tra 100 0 0
accept
rt

You should get two raytrace windows with a simple sphere in them.  If it
does work, try to come up with your own exact sequence of commands or
actions to results in failure.

Bob, this is the first I've heard of this issue, but there was a problem
identified/fixed very recently with how binaries were being searched on
Windows.  Our upcoming 7.16.8 release should have a fix (and has a lot more
Windows testing in it) but I'll work with you on this issue as well with
our 32-bit/64-bit Windows testing outside the tracker system.  Still
working on that test build for you.
