[font=arial]I realize now that I messed up by starting my house design at elevation zero, when I really needed the garage to be at level 0 and the house raised up a few steps.

First I tried setting the elevation of the garage walls at -30" but that didn't work.

Then I grouped everything except the garage, and changed the elevation to 30". Great! That worked, except the walls stayed on the ground and I haven't been able to find any way to raise them.

Can anyone give me some advice? Sweet Home 3D is such a wonderful program, and I have learned a lot, but unfortunately I started doing a plan without reading tutorials first.[/font]
