"No matter what i try" what actually have you tried so far?
"Tek slope doesn't line up" what are you trying to line it up with?

Can you supply screen shots?

I started over again, but getting the same results did try rotate the wall on inner side and out with E in the hope the ceiling would line-up but no differences.

Have you tried cycling through the snap points? Think G or Q by memory.
It look's almost like they're snapping to the wrong point.

Also looking at the video and comparing to your screen shot Nooblets is using vanilla. Look's like the SS/S+ version is intended to have an overhang at the bottom kinda like tiles do.

It doesn't seem to have a cycling option just E rotation for SS Walls and Sloped wall.
Did try with pillars + ceiling also won't line up.
Only way i got it line up is with SS solid foundations but that ruins the build.
Yeah hes using Vanilla but i was just hoping SS would be able to do the same or better :p
Anyways this just my test world, thanks for fast reply :)

S+ isn't really intended to have an overhang.. it's just the result of something that S+ 'fixed' with one snap point or another.. i.e S+ just works differently than vanilla, we use S+ for advanced features that vanilla lacked but there are plenty of things like this example where S+ has it's own issues. Especially with pillars and roofs I've found. You just have to find a work around to get a flush roof. You can follow a vanilla build guide but you have to remember that you might have to get things done in a different way, or accept some slight differences.
