Specifies the prefix and/or suffix that appears in alternate unit dimension text. Use both the left and right square brackets ([ ]) to indicate the placement of a prefix or a suffix. Any text before the brackets displays as prefix text in the alternate unit dimension text. Any text after the brackets displays as suffix text in the alternate unit dimension.
For example, if you set DIMAPOST to 2X [ ] mm, "2X" represents the prefix text and "mm" represents the suffix text. If you then create a linear dimension with a measured value of 1.234, the entire alternate unit dimension text string would read "[2X 1.234 mm]."
To return DIMAPOST to its default settings, type a period at the DIMAPOST prompt.
You can also set DIMAPOST by choosing Settings > Dimension Settings > Alternate Units tab, and typing the prefix or suffix in the fields.
