<t>I use SH3D 1.7 and it is great! I want to make a floor into a ceiling when using the Drawing Rooms feature. I read the Help file about floors and ceilings, but I still do not know how to do this. How DO I do this? <br/>
What I want to do is elevate the room floor into a ceiling. It seems to me ...

Be very careful when using registry cleaners/optimizers, for in earlier versions of SH3D, the red x's will abound.

FYI: As an addendum, "Envisioneer Express" is a 165 MB download, as compared to "Sweet Home 3D 1.4" at 25.5 MB.
