A dimension
style is a named collection of dimension settings that controls the
appearance of dimensions, such as arrowhead style, text location,
and lateral tolerances. You create dimension styles to specify the
format of dimensions quickly, and to ensure that dimensions conform
to industry or project standards.
When you create a dimension, it uses the settings of the
current dimension style
If you change a setting in a dimension style, all dimensions in
a drawing that use the style update automatically
You can create dimension substyles that,
for specified types of dimensions, deviate from the current
dimension style
If necessary, you can override a dimension style
temporarily
