Wall/column intersection 2d display problems

[Anonymous]

I have a column in which four different walls terminate (please see attached). All elements share the same layer intersection value (1) and the same structure (Airspace), yet only one (SW corner of the column) wall intersects "as expected". The column has no veneer.

I can get the north edge of the column to display by increasing its layer intersection value, but that causes other problems.

This is an existing condition which I am documenting.

Any help on where to start would be appreciated. Thank you
