Is there a way to place walls/rails on angled corner foundations?

On the actual angle side?
Not talking about ramps but angled corners.

the angle corners are technically ramps.

I try this using beams, the top should be aligned to the ramps angle. then place a wall on top of the beam. But I never got it looking well

True but i was trying my best to explain it.

There is one wall that snaps to it, but it's a massive triangle wall. Just want a normal 4m flat wall to snap it. Thought some might know a trick that isn't an eyesore.

Maybe use the new hologram lock/nudge feature. Like place a foundation near the corner ramp roughly where you want the wall. Hit H and nudge the wall where you want it.

The Beam Idea above might work too.
A screenshot might help
