I don't think I would worry too much about what your rule shows the printed paper drawing scales. It's probable that he has forgotten to alter the scale on the drawing.

When I worked in a drawing office all the drawing sheets had "DO NOT SCALE" pre-printed at the bottom of the sheet. In the days when drawings were hand drawn there was always the possibility that a dimension had been altered, but not the actual component feature. Took too much time to rub out and redraw.

Now, with most drawings produced by CAD this is probably less of a risk, but it is always best practice to only go by the dimensions. If the dimension is not there then you have every right to complain very loudly. If I had missed a dimension I would not expect someone to have a guess at what it might be.

The drawing sheets still had "IF IN DOUBT, ASK" printed at the bottom and we hoped everyone would follow the advice. Sometimes it was in vain!
