The examples show how to access the following relationships:

  • NX session → list of parts
  • part → list of solid bodies
  • solid body → list of faces
    solid body → list of edges
  • face → list of associated edges
    face → solid body
  • edge → list of associated faces
    edge → solid body

To access all parts in an NX session, use the Parts property to access the Part Collection.  Then use the collection's iterator to access each part.
  Session *NXSession = Session::GetSession();   ParTCollection *partList = NXSession->Parts();  PartCollection::iterator itr;  for ( itr = partList->begin(); itr != partList->end(); ++itr )  {   processPart(*itr);  }9 D: |% T% ^3 W2 Y

To access all solid bodies in a part, use the Bodies property to access the Body Collection. Then use the collection's iterator to access each body.
void processPart(Part *partObject){   BodyCollection *bodyList = partObject->Bodies();   BodyCollection::iterator itr;   for (itr = bodyList->begin(); itr != bodyList->end(); ++itr)   {    processBodyFaces(*itr);    processBodyEdges(*itr);   }}; Y3 {) g% E( F, [# S" \" g

To access the faces of a body use the GetFaces() method to return an array of faces.
void processBodyEdges(Body *bodyObject){    std::vector <Edge *> edgeArray = bodyObject->GetEdges();    for (int inx = 0;  inx < (int)edgeArray.size(); ++inx)          {                        processEdge(edgeArray[inx]);          }}

To access the edges in a body use the GetEdges() method to return an array of edges.

To access the edges for a face use the GetEdges() method to return an array of edges. To access the face's body use the GetBody() method.
void processFace(Face *faceObject){        std::vector<Edge *> edgeArray = faceObject->GetEdges();        for (int inx = 0;  inx < (int)edgeArray.size(); ++inx)        {                processEdge(edgeArray[inx]);        }        Body *bodyOfFace = faceObject->GetBody();} 4 S6 k0 ]$ K# a, E5 C6 e( S9 E
