I have some difficulties accessing the data of objects.
In my case bones.
I need the rotation and translation values from the fixation.

What I have found so far is

  
          BaseContainer bonedata = P406Exporter.doc->GetFirstObject()->GetData();  
          GeData bonepos = bonedata.GetData(BONEOBJECT_FIXPOSITION);  
          GeData bonerot = bonedata.GetData(BONEOBJECT_FIXROTATION);  
  
          GeData bFixed = bonedata.GetContainer(BONEOBJECT_FIXED);  
  
          Matrix mat_rot = HPBToMatrix(bonerot.GetVector());  
          Matrix mat_pos = MatrixMove(bonepos.GetVector());

But the return values are always Null;
What am I doing wrong, and/or where could I find an example how to do it the right way?

Tnx for any help

Nevermind... 1/2 of it was my mistake the other 1/2 was confusion about the GetData GetCustomDataType functions

  
          BaseContainer* bonedata = obj->GetDataInstance();  
          GeData bonepos = bonedata->GetData(BONEOBJECT_FIXPOSITION);  
          GeData bonerot = bonedata->GetData(BONEOBJECT_FIXROTATION);

This way it works (I tried to read bone information from a poly object, so it was my mistake)
But I dont get why there are two functions GetData & GetCustomDataType
