Manual meshing

Manual meshing may be generated as follows:

1. Select Run > Automatic Slab Mesh, then increase the approximate maximum mesh size to a large enough value such that no automatic mesh is created.
   
   
2. Draw null lines along slab edges, then replicate them in each direction.
   
   
3. Select all, then select Edit > Edit Areas > Divide Quads At, and check Intersections with Selected Line Objects Only.
