If you need to install several cabinets 1" away from the wall you can go to Settings and Preferences and set it up in the Standard Dimensions. From that point on all cabinets including wall cabinets will be 1" away from the wall. The "Base Cabinet Mounting Height" and the "Upper Cabinet Mounting Height" defaults can also be changed.
The method that Adam provided you works well for this and also for moving cabinets up and down on an elevation view. Additonally, you should be able to select a whole bank of cabinets and move them 1" away without changing to "Free Style". If you do use the "Move Increment" method, you may need to check to see if the cabinets lose their association to the wall. They may become detached or "disassociated" from the wall if they are moved after their placement. If they are installed away from the wall as setup in Standard Dimensions, they will be associated automatically.
You can also change the settings in Standard Dimensions as described and then move the cabinet away from the wall using the "Move in Wireframe" option (blue cabinet icon with red arrow and the green wireframe of a cabinet being placed). Select the cabinet, then the Move in Wireframe icon and move the cabinet as you would when you first place it. When you use this method, the cabinet will be moved away from its current position and then placed back on the wall at the new Standard Dimension (1" away from the wall). It would need to be repositioned on the wall (left or right). In both cases, when you place a cabinet, the cabinet's position can be influenced by the "Align to Back" placement mode. By that, I mean if you have a cabinet placed against a wall, and then you install a cabinet that is supposed to be 1" away from the wall, the Align to Back feature will override the 1" setting.
Hope that wasn't too confusing. There are multiple methods. Each having their own benefit and behavior.
