Hi
1 Idea .-It will be nice if a existing wall could give the possibility to be attached at the same time to a differents phase roofs, existing and new construction, making the difference with material quantifications, as it happen when we have a existing door, demolish door or a new door in a existing wall,
Actually existing wall can be attached to a new roof but only if this new construction roof is not over the existing
2 Idea.-Shoulnd´t be possible to attach a existing demolish wall to a new roof
