Hello,

Before version 3.4 I simply did a few files for the different floors of my house and the future extension of it. Is there a way to merge them all together now? It's basically 3 files: the original first floor that is about 4ft above ground, the garage, at ground level, and the second floor that will cover the two first file's widths together. I hoped simply copy and pasting would suffice, but no go.

Thanks
K
