Just stumbled on this one.
If you have say a timber deck and want to miter a corner there is all sorts of work arounds, Split Face alone never worked.
Create a floor with surface pattern, select your floor, then select "Modify Sub Elements", then select "Add Split Line", draw your line.
Now you can select and rotate the surface pattern.
Seems to work like Split Face should :banghead:
