Ok I'm doing a N scale layout. I would like to place the walls around my layout, once I set the wall I'm not sure where to set my vertex height at, so if someone could give me an idea, or at least where to start at and then I can adjust from there. After that I guess Ill need to do the dig hole for the floor, so do I use the same vertex height, or different? Thanks for any help, hope this is the right place to post.
