You must be doing something wrong.

Can you post a pic of your Transform/Replicate dbx?

Hey Glen, your comment was past my bedtime.  So, in attempting to post a pic of my Transform/Replicate tool to prove to you that this does not work for walls, I embarrassingly realized that I wasn’t selecting the proper reflect plane. I was selecting Horizontally instead of vertically. 

It’s only when I tried it on a cabinet I realized what I was doing wrong. 

 

Here’s a screenshot of before and after the operation on a cabinet and on a wall.  It works fine. 

 

thanks for your help.
