[cgma-dev] Two bugs involving bricks

[Boyd Tidwell]

Howdy Jane,

  I'm sorry for throwing so many bugs at you.  I know you have other things
you need to do so I don't want you to think I'm expecting you to drop
everything to work on them.  I know you will get to them as your schedule
allows but I'm sending them as I find them so I don't forget.

That said, I have a couple of bugs having to with a brick.

1. Fire Ray problem.

The commands:

   brick x 10
   create vertex location fire ray location 7 0 0 direction -1 0 0 at
volume 1

gives the message:

    ERROR: no ray intersections found
       Unable to find location(s) to create vertices.

  The Acis engine finds two intersections.  I've traced through the code
but it's a bit over my head as to what is going on.  The OCC data
structures are unfamilar to me.

2. Split Surface problem.

   brick x 10
   split surface 6

  It appears the actual split code works.  There is a message "Total 1 cuts
performed, with from_shape having 7 faces." Debug shows that a address
execption occurs when imprinting the new edge onto the surface due to a
BodySM pointer coming up NULL.  I do have a bug on my list I'm working
through involving imprint so this could be related but I thought I'd report
it now in case it's a different one.

Thanks in advance again,

  - Boyd
