Hello every one :)
I'am Priyanka,
Do we have some rules for placing the dimensions on the drawing sheet?

yes priyanka,
We have two systems to place the dimensions which we must follow are as,

a. Aligned system:-In the aligned system the dimension is placed perpendicular to the dimension in such a way that it may be read from the bottom edge or the right hand edge of the drawing sheet. The dimensions should be placed near the middle and above, but clear 0f the dimension lines.

b. Unidirectional system:-In this system all dimensions are so placed that they can be read from the bottom edge of the drawing sheet. The dimension lines are broken near the middle for inserting the dimensions. This system is mainly used on large drawings-as of aircraft, automobiles etc.
