When I scale object it scales in all towards - so the final this object has other x,y,z START coordinates than at the beginning, can I scale object but stay starting coordinates this object ?
Its quite difficult to understand what u r asking but from the bits and pieces I have understood the object when scaled shifts to a different position. To prevent this, untranslate the object with the amount it is translated (this brings the object at origin), scale at origin and then retranslate with the initial amount.
