Just to add to this, a sample drawing attaching a dwg rather than a clip of an image would give everyone a chance to work out what you want. Assuming the mirror command - my first thought - is no good. Things like are the lines shown polylines, lines, leaders, circles. Is the text mtext, text or a dimension text, are the texts consistently offset from the original line or does that vary and even if all the lines are perpendicular to the axis or at angles.. all these things we could get from a sample dwg attached.
