The information in this article applies to:
After placing a sink (or other library item) in a cabinet I am not able to select the sink.
In Home Designer Essentials, Suite and Interiors, sinks, dishwashers and other library items cannot be selected independently once they have been placed in a cabinet. However, you can change the existing item by selecting another item from the library and placing it in the cabinet. At this point you will be asked if you wish to replace the existing item.
The ability to move sinks, dishwashers and other library items is available in Home Designer Architectural and Pro. simply select the cabinet that contains the sink or appliance and then press the tab key on your keyboard or click the Next button on your edit toolbar.
For more information on these versions, see the Products section of the Home Designer software website.
