if you look at the attached screendump, my single skin blockwork wall (on the right) is not cleaning up with the 3 x cavity walls on the left.
all walls are set to 0, 2100 height, and all are on wall priority 2.
the problem is that on section and elevation it is showing that corner as a solid line...
any idea's why it is doing this?
the reference line on all 3 cavity walls is on the outside, and the reference line of the single block wall is at the top side as you look at the screen.
