    I am still struggling with the SendModelingCommand()+MCOMMAND_CURRENTSTATETOOBJECT.

    A standard Sphere is ok, but wat to do with a Null.
    Are there issues or things to check when CST a Null?

    Here my code.

    ModelingCommandData cd;
    cd.doc = GetActiveDocument();
    //cd.op = (BaseObject* )obj->GetClone(COPYFLAGS_NO_BITS, nullptr);
    cd.op = obj;								//Do not Clone!!!
    if (!SendModelingCommand(MCOMMAND_CURRENTSTATETOOBJECT, cd)) return false;
    cstObject = (BaseObject* )cd.result->GetIndex(0);
    if (!cstObject) return nullptr;

    Found it.
    I did not take the correct document (virtual / cache object);

    //cd.doc = GetActiveDocument();
    cd.doc = obj->GetDocument();
