B. Extending a Slab/Roof Slab
Use this procedure to extend a slab or roof slab to a plane defined by another slab, roof slab, or wall. This target object itself does not have to intersect with the extended slab/roof slab, as long as it projects an intersection in the current user coordinate system (UCS).
1) Select the target flat plane
2) Select the first edge to lengthen
3) Select the second edge to lengthen

Tool has local menu item: "By Intersection". If define option "By Intersection":
Use this procedure to miter two intersecting roof slabs. Both roof slabs are trimmed along the intersection of their perimeter lines. Vertices are added or removed as required. The new edges of the roof slabs are set to angles required for a true miter cut. If the slab thicknesses of the two edges are different, the angles are different
1. Select the first roof slab at the side of that slab to keep.
The opposite side is trimmed.
2. Select the second roof slab at the side of that slab to keep.
The opposite side is trimmed.
If does not define option "By Intersection". Mitering Roof Slabs Using Edges
Use this procedure to miter two roof slabs that do not intersect. You can select particular edges to miter. You can miter edges of overlapping roof slabs without trimming the entire slab. To accomplish this, however, you may need to insert additional vertices. Only one edge of each roof slab is mitered.
1. Select one edge on the first roof slab.
2. Select one edge on the second roof slab.
