To align and suppress zeros in tolerance values
1 From the Dimension menu, choose Style.
2 In the Dimension Style Manager, select the style you wish to change and
choose Modify.
3 In the Modify Dimension Style dialog box, Tolerances tab, under Toler-
ance Format, select the alignment from the Vertical Position list.
4 To suppress zeros in primary or alternate units, under Zero Suppression,
select Leading to suppress leading zeros. Select Trailing to suppress trailing
zeros.

Set the Scale for Dimensions
Dimension scale affects the size of the dimension geometry relative to the
objects in the drawing. Dimension scale affects sizes, such as text height and
arrowhead size, and offsets, such as the extension line origin offset. You
should set these sizes and offsets to values that represent their actual plotted
size. Dimension scale does not apply the overall scale factor to tolerances or
measured lengths, coordinates, or angles.
Setting dimension scale depends on how you lay out your drawing. There are
three methods used to create dimensions in a drawing layout:
Dimension in model space for plotting in model space. This is the tra-
ditional method used with single-view drawings. To create dimensions
that are scaled correctly for plotting, set the
DIMSCALE system variable to
the inverse of the intended plot scale. For example, if the plot scale is 1/4,
set the dimscale to 4.
Dimension in model space for plotting in paper space. This was the
preferred method for complex, multiple-view drawings prior to AutoCAD
Release 2002. Use this method when the dimensions in a drawing need to
be referenced by other drawings (xrefs) or when creating isometric dimen-
sions in 3D isometric views. To prevent the dimensions in one layout
viewport from being displayed in other layout viewports, create a dimen-
sioning layer for each layout viewport that is frozen in all other layout
viewports. To create dimensions that are scaled automatically for display
in a paper space layout, set the
DIMSCALE system variable to 0.
