Not quite sure what your problem is: if you want the same
position, why not use the same matrix? Maybe reset the orientation
part fist, if you need to.

But:
Getting the translational component from a DCS is easy:
Just get row 3 of the matrix.

pfMatrix m;
dcs.getMat(m)
pfVec3 pos;
m.getRow(3,pos);

Using this to position another obj is just as easy:
m.makeTrans(pos[0],pos[1],pos[2]);
pfSCS scs(m);

When put under the same node in the scene tree, the scs and dcs will
place their children at the exact same location. Only the orient will
differ.
