Does the editor allow multi-select merging, so you can at least temporarily merge the building and walkways into a single entity for the purpose of movement, copying and placement?asked by It's Only Carl

Yes, it does.

Yes, it does. So what we can do is we can grab this and say this thing, and then we can put them into a group, call it whatever, and then we have this, and you can move the whole thing around. So yeah, we will group things a lot, which is very handy.

I would be surprised, and I'm going to say this and somebody's going to point out a software that doesn't do it, but I would be surprised in any layer-based software that doesn't allow the ability to group, because any subsequent work of significant depth and time is going to get really crazy with the layers, and you've got to be able to group layers.
