The
Tolerance type
defines the way in which the features such as holes and cuts are located
with reference to datum feature.
The
Plus and Minus
option adds location dimensions with + and - tolerances.
The
Geometric
option uses Geometric Tolerance symbols to represent the positions of fea-
tures such as holes and cuts. The type of GD&T symbols used will be based on the
Part
type
. For example, if you set the
Part type
to
Prismatic
, the Position symbol will be used
to locate a hole. However, if the
Part type
is set to
Turned
, the Circular Runout symbol
will be used to position a hole.
Next, you need to define the datum features. A datum is used as a reference to measure the
location, shape, and size of a feature. A datum can be a surface, point, or axis.
