Hi Mindset,

> Don't understand what gives here:

Dimension values are rounded using the setting under Formatting > "Decimal display" for decimals and Formatting > "Fractional display" for feet & inches.

So if you want to display a fraction less than that you'll need to set the display precision to be tighter. You can set the default used for new dims under Options > Dimensions, and you can set the properties for existing ones by selecting it and pushing "Details...".

If you're still having a problem can you please post the .3dm model file with your dim in it so I can take a look.
