Hi Joe,
I guess that I must not have been too clear with the explanation.

Interesting that I never received an email that you had replied. Anyway, after experimenting for 5 hours I found the setting. It was in the toe kick properties titled ‘End panel inset distance’ I didn’t realize this property can take a negative number. By changing that to -1″ the right side toe kick on the divided base cabinet joined up with the toe kick on the blind base cabinet beside it.

Many thanks, Wayne
