second floor on top of first?

[trailsnet]

I'm trying to build house plans for the first time using Home Designer Suite 2016. I started by using the terrain builder (no problem) for the lot, then I added the main house structure (no problem), then I tried adding a second floor. Laying out the second floor was no problem. But now it shows in the plans as if it's a completely separate entity from the first floor. (I've tried attaching a screenshot of how it looks on my computer screen to give you an idea, but I'm not sure if the screen shot will work.) 

 

Anyway, how do I get the second floor on top of the first floor so I can view it and work with it as one complete unit/house?

 

Thanks.

You could select the entire second floor and move it into place. Press F9 to show the reference display.

 

Or just delete the 2nd floor and redraw. Build>Floor>Build New Floor
