PRIN. OF DRAFTING AND SHOP DRAWINGS - OD1641 - LESSON 1/TASK 4
EXAMPLES OF ANGLE AND HOLE
(5) Dimensioning Small Distances and Small Angles.
When dimensioning a small
distance or a small angle, always keep the lettering at the normal height of either
1/8 or 3/16. The temptation is to squeeze the dimensions into the smaller space.
This is unacceptable because crowded or cramped dimensions are difficult to read,
especially on blueprints which are microfilmed. Figure 72 (on the following page)
shows several different ways to dimension small distances or angles and still keep
the dimensions at the normal height.
