AC9 brings the ability to save views with different dimension settings. The most prominent example would be the desire to dimension plans with feet & fractional inches, and site plans with decimal feet. Now you don't have to switch dimension settings back and forth, or explode dimensions, or other such tedium.
To make it easier to maintain the dimension settings, we use the long-standing, little-noticed Dimension Standards.
"Standards" in Dimension Preferences
There are two standards which we use in our views. "Site" is used for site plans. "Plan" is used for everything else. You could also set a standard for details if you wanted to display smaller fractions.
The view sets in the templates are configured to use the appropriate standard. For running projects, you will have to redefine your site plan views. Set the "Site" standard in the dimension settings, then redefine the view. (It's just like changing the scale or the layers.) Your plans should be OK, but it never hurts to check.
So now, views save scale, layers, display options, zoom, and dimension standard.
