Vertical start a wall above ground, how?

[Carrock]

Hi all

Anyone knows how to move a wall up?

What i need to do is to create the triangle in the top above a window when the wall below is not full height.

Below you can see the wall is not full height, but how do i then add a wall on top that covers the area above the window?



Thanks

1 - split the wall in two parts, and make both parts sloping
or
2 - insert a triangle
or
3 - insert a level with the correct elevation where you put a wall, split the wall in two parts, and make both parts sloping

Great, thanks

Adding a new level with a modified height made it work.
