4.5.2.4 Orientation
The dimensions are indicated on the drawings according to one of the following
two methods. Which are :
Aligned method
Dimensions should be placed parallel to and above their dimension lines and
preferably at the middle and clear of the line.
Figure 4.17 : Aligned method
Uni-directional method
In this method, dimensions should be written properly so that they can be read
from the bottom of the drawing only. If non-horizontal dimension lines are
interrupted, it is preferably written in the middle for insertion of the dimension.
