The standard roof truss spacing is 2.

Roof truss offset.

Showing the bevels on the ridges and h v rafters adds to the confusion. A cantilever truss allows for level coverage past the exterior wall such as patios porches entryways and other offsets in the building elevation by moving one or both bearings inward from the end of the bottom chord up to 1 4 of the span. This is the distance between trusses. There may be an overhang at the end of a cantilever.

Light gage cold formed steel structural steel stainless steel and aluminum.

Just as there are many types of roofs with many roof parts there are many different types of roof trusses this extensive article explains through a series of custom truss diagrams the different truss configurations you can use for various roofs. 3 the offset height of the flat topped ridges is correct.
