In the code, when the target dimension is the same as source dimension, we return just the entity.<br>
AEntityFactory.cpp:<br>
...<br>
599 else if (source_dimension == target_dimension) {<br>
600 target_entities.push_back( source_entity );<br>
601 result = MB_SUCCESS;<br>
602 }<br>
603 else {<br>
<br>
As a workaround, you probably want to go through edges/vertices, and from edges/vertices get the adjacent triangles.<br>
<br>
Tim, should we change the behavior and return all adjacent triangles? I know that there is a discussion in iMesh too about that.

<pre>hello,
are you using the last parameter / flag to the get_adjacency? By default it is intersect.
maybe you want "union" of the input ?
virtual ErrorCode get_adjacencies(const Range &from_entities,
const int to_dimension,
const bool create_if_missing,
Range &adj_entities,
const int operation_type = Interface::INTERSECT);
What are you getting and you do not expect it?

Subject: [MOAB-dev] get_adjacencies of same dim
Hey all,
Quick question. Working on a couple tests for ReadCGM and calling for
the adjacencies of an entity which are the same dimension of the entity
itself but I'm not getting the result I'm expecting. Any this special to
know in this case?
Cheers,

I'm calling for the adjacencies of a triangle which I would expect to return a vector of entity handles of size 3, but it seems to be returning a vector of size 1.<br>
<br>
To be specific I'm using:<br>
<br>
<br>
<pre>virtual ErrorCode get_adjacencies(const Range &from_entities,
const int to_dimension,
const bool create_if_missing,
std::vector<EntityHandle> &adj_entities,
const int operation_type = Interface::INTERSECT);
and here's my call: get_adjacencies( tri, 1, 2, false, adj_tris);
