Hi Ahmet, Sorry for no answer, I have been in holidays. The answer to your question is : - yes, but only if R is positioned inside O (which is probably not exactly what you want). The idea is that you always position objects with respect to the coordinate system of their container, e.g: container->AddNode(R, cpyNo, mat); where: mat is the matrix defining the position of R with respect to 'container'.
