Fill pattern with block

Hi all,

I am trying to determine how I could pattern a block (in this case a small square with some corner features).  I tried using a MINSERT command and then XCLIP.

The issue is that XCLIP will cut through the block geometry.  However, if the boundary were to contact any portion of the block, I would want the entire block trimmed.

The issue is that I have literally 10's of thousands of these blocks so I can't do anything manually.

Thanks!

Mike
