Tim, I appreciate your time;

I will look into each of these points;


however,
Question: why did you say object is scaled other then 1 (cube 'A'); I
believe that my objects are scaled to 1 ( specifically, when using
my_DAE.scaleX/Y/Z ==> 100, when using my_Collada.scaleX/Y/Z ==> 1 ); and I
do not find the word 'scale' in my .dae;
