How to fix two problems: attic wall with part over roof, and wall connection for post/beam porch railing

[GeneDavis]

Here is a camera view with both issues highlighted.  The gable wall with fake window centered under peak is killing me.  I am unable to generate the wall so it shows properly in 3D.  Its right half is "roof cuts wall at bottom" and needs to have that spec so it doesn't protrude into the vault space below.

 

The other is the beam atop the railing (post and beam).  The corner join won't render correctly.  There are OK corner joins all around the porches.  Note the wall spec with the offset posts and beam.  Both are offset horizontally so I can get the slab edge 3" past the wall line, so columns do not bear right at the edge.  This corner has one of the walls NOT offset, and it needs to be this way.
