I'm on Home Designer Architectural 2015.  

Thanks all for the comments. 

Seems like there should be an easy way to address this problem.  I will have to prepare a demo plan so the suggestions above should help.

One of the issues I found with this question is the roof pitch.  The existing house a lower pitch than I'll need for the addition, but when I change the pitch for the addition the existing house pitch changes.

Just started using the software, so I'll eventually figure it out. 

How do you show an addition as new construction and the existing house in present state?

I want to do a framing plan for an addition without showing the existing house framing.
