Benefits and Description

In the Dimension Property dialog box, you can set the following expression: =( ). This expression takes the result of a calculation in the parentheses and displays the exact result on the dimension field. This exact result has the minimum number of decimal points needed to display the dimension in its exact value or to the number of decimal places defined by the configuration option default_dec_places. Exact values override the number of decimal places currently set globally or locally for the dimension. For example, if you type =(360/29) in the dimension field, the value read is 12.413793103448 and the number of digits for the dimension is set to 12. In 3D, the dimension appears with trailing zeros sufficient to show the number of decimal places defined in the dimension properties. In 2D, the display of trailing zeros is controlled by the Detail Setup option, lead_trail_zeros.
