Hi Jane,<br>
<br>
I think this needs a thorough review! Patrick and I hunted through
iGeom_CGMA and found some inconsistencies in a few places.<br>
<br>
First, there is an inconsistency between returning pointers to
RefEntity and pointers to CubitEntity. This is probably less
important, but should probably be resolved in any change.<br>
<br>
Second, there are places where the geometry is queried for entities
of dimension=3 (returning RefVolumes) and places where the geometry
is queried for entities of type=iGeom_REGION (== Body).<br>
<br>
This means that 2 calls into the interface that should resolve to
the same entity may not do so for both reasons.<br>
<br>
All of this is related to the fundamental difference between the
iGeom types (equivalent to vertex, edge, face, volume) and the
CGM/ACIS types (equiavlent to vertex, edge, face, volume, body). I
think Tim's suggestion is the best, but will require some
substantial effort.<br>

<div dir="ltr">I see in iGeom_CGMA.cc file,
function iGeom_get_adjacent_entities, if asks for 3-D
refentities, it returns body list. In CGM, bodies are not
necessary to be 3-D entities, it may contain single surface or
shell. Should we change the return to be only refvolumes which
are 3-D entities (I prefer this, makes more sense)? Or I can
return both bodies and refvolumes in the returned refentity
list. Depending on your user case, I can return one of the two
choices.

I looked around for this but
didn't see it, is there a
specific line/function you were
thinking of? Good to know the
ref_volume information is so
easy to get to, but it doesn't
seem that its part of the iGeom
interface. The issue being that
there's no way to access a
body's volumes via iGeom. <br>
