Two dialog windows let you build a fragment or brick wall.
This first window lets you generate the zoning.
The fragment/brick wall is built with its axes parallel to the X, Y, and Z axes.
The X direction runs the length of the wall.
The Y direction runs the height of the wall.
The Z direction runs through the thickness of the wall.
The number of fragments/bricks in the X, Y, and Z directions.
The length of a single brick/fragment in the X, Y, and Z directions.
The mortar size (or gap) between fragments/bricks.
Check this box if you want the mortar size to be included in the length of each brick/fragment.
The number of elements per fragment/brick in the X, Y, and Z directions.
The offset ratio for the fragments/bricks.
This is how the bricks are staggered along the length of the wall. For example, if the offset is 0.5 (the default), the bricks will be staggered halfway across each other as shown in the above figure.
Check this box if you want the wall to be symmetric about X=0.
