Wedge shaped Void from Mass

[ace84]

Hi
I am trying to create a 7 degree angled wall by ultimately using the Wall By Face of a mass.
I have created my solid mass by selecting the outer edges of my ground level slab and extruding it up 50'.
My south wall and north walls are to be sloped 7 degrees to the north.
My work plane is at ground level for the sketch, I'm not sure if this is relevant.

How can I achieve this using a Cut Extrusion?

Or am I using a totally wrong technique.

Any input is appreciated.

You can 'carve' your basic extrusion with a void sweep along the south and north walls. You need to create the void sweep while in the same in place family as the extruded mass.
You can create the sweep path by picking the edges of the extrusion and a ref plane will appear perpendicular to the first path line. You then draw the profile you want on that ref plane and it will sweep around the extrusion.

Depending on what you are trying to achieve you can eliminate the solid all together and just create the mass object that is the form for the battered wall. This can sometimes cause issues with wall joins at the ends of walls created using the walls by face option.
