Hi Angie
There isn’t a specific blind cabinet in the catalog but you could use one of the options available and edit the size to match the size of the blind cabinet you are using. For that option I would recommend turning off the countertop for all of your cabinets and inserting a single countertop piece to cover all cabinets so it looks more seamless.
If you haven’t put in a separate countertop before you: select Insert>Interiors> Countertop
Or you can use the Surfaces tool. Here is a video on how to use surfaces for a countertop: https://www.cadsoft.com/surfaces/
