Hello all, I am trying to create a steel joist dynamic block, that my office could use in our wall sections.  I thought i could array the joists web and then insert a wipeout that would cover any excess array that past the section mark.  Unfortunately even though I made sure the array was brought to the front and the web sent to the back (draw order) in the block, the array still shows through the wipeout.  Does anybody know anything I can do to fix this.  I have attached the block as is.  Any help would be much appreciated. uploads/265993/Steel_Joist_Block.dwg
