That is the thing.
The base of the wall is flat.
It is trimmed on an angle in 3D but this does not show on plan.
It shows in plan as if the wall is still flat - which it is.
If the base is below the cut plane you will see the cut for the entire length of the wall - regardless of how it appears in 3D.
If you select the wall in 3D you will still see nodes on the part that has been cut off.
Split the length into 2 and hide the bit you don't want to see on a layer that is turned off in plan but on for sections, elevations and 3D views.
