4.   Now we need to add reference planes where the detail lines intersect both the front and back reference planes. To make it easier for us in our elevation name them using the previous method according to their position. That is, the reference planes associated with the first tread should be named B1 and F1 (B=back, F=front), then continue this numbering method up the stairs. Also make sure the reference planes properly intersect the view, that is the 3D extents overlap the elevation boundaries.
