Any support documents how to use this utility?  I loaded it into AutoCAD, but what are the commands?Thx,Mark Simpson

How to use what utility?

CuitoMnu.  I found it.  For some reason the first time I loaded it the text line telling me to type "CuitoMnu" didn't show.  After a restart and reload, the instruction popped up.

My next question about CUI to MNU:I am trying to convert back a custom CUIX file to use on previous AutoCAD versions.When I unzip the CUIX file from AutoCAD 2010, there are 20 CUI files in there.In order to make a single CUI file that will work in AutoCAD 2006, can I just combine all the text in those files into a single CUI file?  Starting with the Header file and inserting the rest before "</CustSection>"?Can I skip the CUI files that don't have any custom information?Thanks,Mark Simpson

Trying to convert back a custom CUI to use on AutoCAD 2006?It begs the question..."Why"?  Any functionality present in the 2010 CUI that was not present in the 2006 CUI is going to be worthless isn't it?
