Disable wall "merging"?

[madcowscarnival]

I'm trying to create a drawing for as-built conditions.  One side a framed wall is set on a concrete stem wall ~80" above grade.  About half way along its length the concrete stem wall drops to 36" above grade.  CA works fine when one side is pony wall conditions and the next is full height framed.  But, as soon as I change that next wall to a pony wall it automatically merges both walls and makes the lower wall height the same along the full length when I close the dialog box.

 

I'm sure this is something I can turn off, but I don't know "what" to call it for a search.

PitMan, thanks for the reply.  Did some searching with that language, looks like that's something added in a later version than what I have.  Appreciate it though.

A follow up for when I search this in the future.  I was able to edit the pony wall height in elevation, rather than the dialog box, and it appears to be "sticking" for now.  I'm not building framing or anything like that, so don't know if this is anything other than appearance only.

In older versions, to prevent walls from merging, all you need to do is change one of the main wall settings.  Changing the height will work, but it can mess up the model.  Changing the wall layer or wall type should also work.
