<p>Type of a geometric model entity (GREGION, GFACE, GEDGE, GVERTEX,</p>
|
||
|
||
<p>GUNKNOWN). Typically can be used in conjunction with the operator to</p>
|

|

<p>get mesh entity classification. So one can get the model entity a mesh</p>

<p>vertex is on, query what type it is and do something based on the</p>
|
||
|
||
<p>response (e.g. reposition the vertex only if it is classified in a</p>

<p>model region).</p>

|
||
|

<p>Given <em>nent</em> entitities (the entity pointers given in <em>gents</em> and their
|
||
types in <em>types</em>), find their common entities, <em>cgents</em>. The entities
|
||
will be of the lowest order possible (but higher than the highest order
|
||
of the input entities). For example, if we were given two model edges
|
||
connected by one common face, the output would be this common face. On
|
||
the other hand if these edges were not connected by a common face but
|
||
the faces connected to them are on the boundary of the same model
|
||
region, the model region would be returned as a common entity.
|
||
Naturally, there may be more than one such common model entity in
|
||
general geometric models.</p>
