I'm not sure I understand how you guys use bearers. Over here we use sill plates (footers, called different things) they are anchored right to the foundation, and is what the rest of the building (floors generally, but could be walls) is attached to. They are generally 2x6 or so on the flat (the metric equivalent I don't know off hand). I tried making a bearer of that dimension by changing the thickness to the width. I just got an error. Is there an easy way to do this that I am missing?
Not that it matters really, but how do you use bearers? they just seem like more floor joists...
