Click OK on New Dimension Styles dialog.
Click Set Current and Close on the
Dimension Style Manager dialog.
Apply dimensions to the drawing.
Create a new dimension style with the name
Tolerances.
In the New Dimension Styles dialog, click
the Tolerances tab.
In the Tolerances tab, set the Method as
Deviation.
Set Precision as 0.00.
Set the Upper Value and Lower Value to
0.05.
Set the Vertical position as Middle.
Specify the following settings in the Primary
Units, Text, and Symbols and Arrows tab:

Geometric Dimensioning and
Tolerancing
Earlier, you have learned how to apply tolerances to
the size (dimensions) of a component. However, the
dimensional tolerances are not sufficient for
manufacturing a component. You must give
tolerance values to its shape, orientation and
position as well. The following figure shows a note
which is used to explain the tolerance value given to
the shape of the object.
Text tab:
Text Height: 2.5
Text placement:
Vertical:Centered
Horizontal:Centered
Text alignment: Horizontal
Symbols and Arrows tab:
Arrow Size: 2.5
Center Marks: Line
Providing a note in a drawing may be confusing. To
avoid this, we use Geometric Dimensioning and
Tolerancing (GD&T) symbols to specify the
