The Dimension command allows to change dimensions styles. These changes will apply to new dimensions, but won't affect dimensions that already exist in the drawing. In order to apply changes to all dimensions it is required to run the Dimensions regen command. .
This command also updates dimension texts after editing the dimensions geometry (e.g. during dimension stretch).
This command does not display any dialog window, therefore any results of this command can be read only in the CAD program command line.
