Walls can now be multilayer, with a very simple trick: Several walls can be based on a same baseline, specifying an offset distance from the baseline. This, combined for example with Arch Frames, allows for example to create complex framed walls, or walls with an insulation layer. Furthermore, these walls are aware of their "brothers" (other walls based on the same baseline), and any window placed on one of these walls will also create a hole on its brothers.
