DESIGNrev: remove all polygons and references underneath a rectangular area

Hello All,

 

I'm hoping this is the correct place to post this question.  In DESGINrev, is there a way of efficiently removing all shapes (polygons, references, paths, etc.) that lie beneath a rectangular area that is specified at the top level cell?  My goal is to take an existing (~40GB) tiled GDS database, and "chop" a rectangular hole in it from the top level and through the rest of the hierarchy.  My intention is to then drop in another IP block within that "hole".  I understand how to do this by hand editing in the DESIGNrev gui, however, the process is slow, tedious, and prone to error.  If anyone has any advice they can share for efficiently accomplishing such a task, I would be very grateful.  Thank you!

 

Best Regards,

 

George
