2. TYPES OF DIMENSIONING SYSTEM
1)CHAIN DIMENSIONING
2) PARALLEL DIMENSIONING
3)SUPER IMPOSED DIMENSIONING
4) COMBINED DIMENSIONING

3. Chain Dimensioning
1)Chain dimensioning is when each single
dimension is placed directly adjacent to the
next dimension without any gap between
dimensions line.
2)This method should only be used if
tolerance accumulation is not going to affect
the function of part.

4. 2) PARALLEL DIMENSIONING
When numbers of dimensions are
measured in the same direction from a
common feature, i.e. surface of the
part, then method of indicating all the
dimensions from the same feature is
called parallel dimensioning.
The dimension lines are parallel to
each other and equally spaced

5. 3) SUPER IMPOSED DIMENSIONING
Superimposed running
dimensioning simplifies parallel
dimensions in order to reduce the
space used on a drawing.
The common origin for the
dimension lines is indicated by a
small circle at the intersection of the
first dimension and the projection
line.

6. 4 COMBINED DIMENSIONING
The type of dimensioning in which the
dimensions are arranged parallel to
each other is called a Parallel
Dimension.
The combination of both the type is
called as a combined dimension. ...
In the combined dimension, the
dimensions are arranged in a straight
line only.
