Newbie needs help making new floor UNDER existing floor HD Suite 2014

[PickyBiker]

I have a sloped lot that lends itself well to 3 floors with the 1st floor at the bottom of the slope and only half as deep as the main floor. The main floor is next and the 3rd floor is also only half as deep as the main floor. From the side, it will look something like this:

----- top floor
---------- main floor
----- bottom floor


My problem is that I started with the main floor and got it fairly well done. Then I added the top floor and got that done. Now I want to build the bottom floor which rests on top of the foundation and under the main floor and I don't know how to insert that.

Is there a way to insert another floor there or do I need to start over from the bottom floor?

Thanks,

PickyBiker.

I don't think anything other than Pro has the Insert Floor option, but you can do this.

Create a new, blank Floor 3.

Drag a marquee around everything on Floor 2 and select Edit> Cut.

Go up to Floor 3 and select Edit> Paste> Hold Position.

Repeat to move Floor 1 up to now blank Floor 2, leaving an empty Floor 1 for you to draw the lower level on.
