4.5.2 The dimensions on the drawing should include dimension boundary, ruler line, dimension start and end symbols and dimension numbers. 4.5.2.1 The dimension boundary should be drawn with thin solid line and should be perpendicular to the length to be marked. One end should be not less than 2mm away from the outline line of the drawing, and the other end should be 2m~5mm beyond the dimension line. If necessary, the outline line and center line of the drawing can be used as dimension boundary. 4.5.2.2 The dimension line should be drawn with thin solid line and should be parallel to the length to be marked and should not exceed the dimension boundary. No line of the drawing should be drawn with a full line.

When oblique lines are used, their inclination direction shall be 45° clockwise to the dimension boundary line, and the length shall be preferably 2mm to 3mm. However, only one type can be used in the same drawing. See Figure 6 for dimension line marking. 4.5.3 Dimension numeral marking shall comply with the following provisions: 4.5.3.1 The dimension numeral marking direction shall be in accordance with the provisions of Figure 7; dimension numerals shall not be marked within the 30° oblique line. When it cannot be avoided, they shall be marked in accordance with the form of Figure 8.
