• material
  The material index that shall be assigned to the volume that makes up the brick.
• sloppy
  Possible values are yes, no. If no, meshplanes are enforced at the borderplanes of the brick.
• whichcells
  Possible values are all, or a material-index. If whichcells= all, all volume inside the brick is assigned the material-index, provided the former material is not taboo. If whichcells is a material-index, only the parts of the brick that are currently filled with the given index are assigned the new material-index.
• taboo
  Possible values are none, or a material-index. If taboo= all, all volume inside the brick is assigned the material-index. If taboo is a material-index, only the parts of the brick that are currently filled with another index than the given index are assigned the new material-index.
• show
  If show=now, an outline of the brick is shown.
  If show=all, an outline of the brick together with outlines of other bricks, ggcylinders, gbors and gccylinders is shown.
  If show=later, the outline is not shown immediately, but is recorded to be shown later together with the outlines of other items.
• xlow, xhigh, ylow, yhigh, zlow, zhigh, volume
  The coordinates of the bounding planes of the brick. Alternatively to specifying via xlow.., you can specify the volume of the brick as
  volume= (XL, XH, YL, YH, ZL, ZH).
• doit
  Puts the current data into the meshing database.
