CAD tip # 7864:

The LISP function (rtos 0 4 2) gives just 0" in imperial units.

The display format of zero values is controlled by the DIMZIN dimension variable. Set DIMZIN=1 to display 0'-0" for zero lengths.

DIMZIN values:

• 0 - Suppresses zero feet and precisely zero inches
• 1 - Includes zero feet and precisely zero inches
• 2 - Includes zero feet and suppresses zero inches
• 3 - Includes zero inches and suppresses zero feet
• 4 - Suppresses leading zeros in decimal dimensions (e.g. 0.5000 becomes .5000)
• 8 - Suppresses trailing zeros in decimal dimensions (e.g. 12.5000 becomes 12.5)
• 12 - Suppresses both leading and trailing zeros (e.g. 0.5000 becomes .5)
