creo7 Drawing Setup option documentation for: VIEW_SCALE_FORMAT            


view_scale_format

Formats the drawing and view scale ratio.
Default and Available Settings:
decimal* - Expresses the scale value as decimals.
fractional - Expresses the scale value as fractions.
ratio_colon - Displays the scale values as a ratio. For example, instead of the scale value of 0.5, displays the scale value as 1:2. Since the ratio is just another way of displaying a fraction, make sure that you set the view_scale_denominator Detail option appropriately.
ratio_colon_normalized - Displays the scale value as a ratio that is normalized to have 1 as the numerator for scale less than 1:1, and 1 as denominator for scale greater than 1:1, as follows:
o For scale less than 1:1 - The numerator appears as 1 and the denominator appears as the value that you set for the scale. For example, 1:2, 1:12, 1:2.5.
o For scale greater than 1:1 - The denominator appears as 1 and the numerator appears as the value that you set for the scale. For example, 2:1, 10:1, 2.5:1.
* 
With the ratio_colon_normalized setting, some scale values can result in either the numerator or the denominator to appear as a decimal value, without the trailing zeros, and rounded to maximum of three decimal places. For example, with the ratio_colon_normalized setting, a scale value of 2:3 will appear as 1:1.5.
