Thank you!!You've been very helpful.
One last (I hope) question: is there a free software or (a way with trueview) that allows me to save a dxf/dwg file in a pdf format where the draw appears on screen in its actual size?
(I tryed many times and in many ways with TrueView 2012 but the draw was always in differen/bigger size even if the zoom was at 100%:measuring the dimension with a ruler, the dimensions on screen are bigger than the draw (the draw is correct: when i plot it, it'correct)
