how to get point of layer that i want in window cell view

Noobnoob

Hello, i am sorry for my English skill.

i am noob for cadence skill language.

As the title says, in window cell view, i want to know point(coordinate) of layer i want

i made a cell named "DECAP" and i placed "DECAP" as mosaic ...

Poly layers is in different hierarchy.

in order to find out all point of Poly layers, i made a script by using skill language...

Script :

wcv = geGetWindowCellView()
overlaps = dbGetTrueOverlaps(wcv wcv~>bBox list("POLY" "drawing") 32 t)

transform = nil
temp = nil
label = nil

foreach(overlap overlaps
transform = append( transform list(dbGetInstTransform(overlap)) )
);foreach
foreach(i transform
temp = append( temp list(nthelem(1 i)) )
);foreach

Result :

((4.2 4.2) "R0" 1.0)
((4.2 4.2) "R0" 1.0)
((4.2 4.2) "R0" 1.0)
((12.2 4.2) "R0" 1.0)
((12.2 4.2) "R0" 1.0)
((12.2 4.2) "R0" 1.0)
(((db:0x1fa1cc9b 0 0) db:0x1fa1ada3)
((db:0x1fa1cc9b 0 0) db:0x1fa1add4)
((db:0x1fa1cc9b 0 0)
(db:0x1fa14b9a db:0x1fa14ca0)
)
((db:0x1fa1cc9b 0 1) db:0x1fa1ada3)
((db:0x1fa1cc9b 0 1) db:0x1fa1add4)
((db:0x1fa1cc9b 0 1)
(db:0x1fa14b9a db:0x1fa14ca0)
)
)

i don't know meaning of (4.2 4.2), (12.2 4.2) ... as result of dbGetInstTransform.

please help me, i want to find out point of poly layer in different hierarhy, in mosaic cell...

    thank you, guys!

    i took a first step for my problem and solved it !!

    as i want, i got a point list.

    next step, i'm going to apply point list to dbPointArrayOr function.

    for example, point_list = ( ((0 0) (5 5)) ((0 5) (5 10)) ((0 10) (5 15)) )

    i think that dbPointArrayOr(wcv point_list)'s result is ( (0 0) (5 15) )

    but, actually, dbPointArrayOr function don't operation.

    what's wrong for me...?

    Thank you for always leaving comments.

    The “point list” you are providing is not a list of point lists but rather a list of bounding boxes. dbPointArrayOr will treat this as a list of point lists, and so each of your bounding boxes will be treated as a two-point diagonal line from the lower left to the upper right, and so you are trying to or three zero-area diagonal lines, and hence the result will be nothing.

    In other words, each point list needs to be the outline of a polygon; if you were starting from the coordinates in a bounding box ((llx lly) (urx ury)) then it would need to be ((llx lly) (urx lly) (urx ury) (llx ury))
