You can list the dimension styles in the current drawing. You can also list all dimensioning system variables and their current status or only the variables affected by a dimension style.
When you list the current status of all dimensioning system variables, AutoCAD LT lists any running overrides that apply to the current dimension style. For an example of the settings for a dimension style, see Example: The Default Dimension Style.
You can also list the differences between a named dimension style and the current dimension style, as in the following example.
Differences between STANDARD and current settings:
| STANDARD | Current | Setting |
| DIMASZ | 0.1000 0.1800 | |
| DIMBLK1 | _OPEN | |
| DIMBLK2 | _OPEN | |
| DIMCLRD | BYBLOCK3 | (green) |
| DIMCLRE | BYBLOCK3 | (green) |
| DIMSAH | Off | On |
| DIMTAD | 0 | 1 |
| DIMTIH | On | Off |
AutoCAD LT displays externally referenced dimension style names using the same syntax as for other externally dependent symbols. The name of the xref is combined with the dimension style name, and the two names are separated by the vertical bar (|) character. For example, if the drawing baseplat.dwg file has a dimension style called FRACTIONAL-1 and you attach baseplat.dwg as an xref to a new drawing, then the dimension style appears in the new drawing as BASEPLAT|FRACTIONAL-1.
Externally referenced dimension styles can be examined, but they cannot be modified or made current. You can use an externally referenced dimension style as a template for creating a new dimension style in your current drawing. For more information, see Creating Dimension Styles.
