Attic beams

To create the beams for the attic I used the beams created for the previous floors.

I created another beam and rotated it so that it was lying diagonally across the two beams that had already been placed. I then used the array tool to create the rest of the beams.

Next I applied a symmetry modifier and adjusted the symmetry gizmo to adjust the mirroring of the beams.

I added some smaller beams joining the two beams that were placed at the beginning and added another beam on either side along the length of the attic.

I adjusted the position of some of the beams so that they fitted inside the roof of the guildhall.
