creo5 Drawing Setup option documentation for: DIM_TRAIL_ZERO_MAX_PLACES            

(Also MBD)

dim_trail_zero_max_places

Sets the maximum number of decimal places for dimensions and dimension tolerances when trailing zeros are used to attain the maximum number of decimal places defined by the default_dec_places configuration option. Specify a value that is less than the specified number of decimal places for dimensions to control the number of trailing zeros.
Default and Available Settings:
same_as_dim
 
This Detail option does not affect decimal places if the value specified for the lead_trail_zeros Detail option prevents trailing zeros from being displayed.
This Detail option affects the display of all dimensions in a drawing. You cannot individually control the number of decimal places for dimensions with trailing zeros.
This Detail option does not affect angular dimensions displayed in the degree, minute, and second format.
Consider the following example:
1. Specify the value 2 for the default_dec_places configuration option.
2. Specify the value same_as_dim for dim_trail_zero_max_places.
3. Specify the value both for lead_trail_zeros.
4. Click Format > Decimal Places and type the value 6. Trailing zeros are added for dimensions whose values do not extend upto 6 decimal places. Such dimensions are identified by an arrow as shown in the following figure:
In this example, if you change the value of dim_trail_zero_max_places to 3, trailing zeros are added for all dimensions with values less than 3 decimal places. Such dimensions are identified by an arrow as shown in the following figure:
