how to cut an array of rectangles in a big rectangle?

kentlintu

Hi All,

I am a newbie to SKILL programming and need help on the following question that seems simple yet getting me stuck for a while. Any help will be appreciated!!

What I am trying to do is simple: I would like to cut several repeated rectangle holes in a rectangle. I have no idea how select the bunch of squares at once and generate the wanted rectangle with holes.

; create the big rectangle

bigrectangle = dbCreateRect(pcCellView mylayer list(0:0 10:5))

; create the array of rectangles

for(i 1 10

xxx = dbCreateRect(pcCellView mylayer list(i*2:4 i*2+1:6)) ;<----------------------------------?? don't know how to  select the rectangle array at once and then eventually delete it after layer generation

)

layerAndNot( pcCellView mylayer list(bigrectangle) list(xxx))

dbDeleteObject(bigrectangle) dbDeleteObject(xxx)

    Something like this should work:

    ; create the big rectangle
    bigrectangle = dbCreateRect(pcCellView mylayer list(0:0 10:5))

    smallRectList=nil

    ; create the array of rectangles
    for(i 1 10
      smallRectList=cons(
        dbCreateRect(pcCellView mylayer list(i*2:4 i*2+1:6))
        smallRectList
      )
    )

    dbLayerAndNot( pcCellView mylayer list(bigrectangle) smallRectList)

    dbDeleteObject(bigrectangle)
    foreach(smallRect smallRectList
      dbDeleteObject(smallRect)
    )

    Regards,

    Andrew.
