Do not repeat dimensions if you already have them or they can be worked outfrom others you have on the drawing. Place dimensions in the clearest possible way.

Dimensions should be read from the bottom (horizontal lines) or right handside (vertical lines) Dimension values must be placed above and parallel to dimension line. 13.
