Prefix To Dimension Figure

In dimensioning, a prefix is added automatically to a diameter and radius dimension and an arc length dimension.

If you want to add another prefix to a dimension to replace the automatically added prefix, select the auxiliary Prefix function.

You can type the prefix in the field.
Select a previously used prefix from the list.
Select the character from the list by clicking the Character button in the field.

The prefix defined in the field is valid until the field is cleared.

If you want to use the automatic prefix in dimensioning, disable the Prefix function.
