You can specify a thickness in the X, Y, and Z directions for plates, gussets, and
end caps.
Note:
You must define all the axes in the axis system correctly to orient plates,
gussets, and end caps at the proper location. The X and Y axes define the horizontal and
vertical lengths and the Z-axis specifies a direction for thickness.
