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></div></blockquote><div> </div></div><div>I see RefEntity is inherited from CubitEntity, and CubitEntity is a pure virtual class. So even you got pointers to CubitEntity, you have to instantiate it to RefEntity objects.</div>

<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></div></blockquote><div><br></div></div><div>In this case, I can return both bodies and refvolumes, so after user gets the refentity list back, he can cast to see if they are bodies or refvolumes, and choose to keep what ever he needs.</div>

<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.<span><font color="#888888"><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>
