Coordinates(bBoxes) of all the shapes(layers) in a layout view

This is possible, but some context as to why would help. There are multiple shape types... Rectangle, Polygon, Path, Elipse, Donut, pathSeg. The coordinates are expressed differently for the different objects. e.g. A rectangle has a bBox, a path a list of points with a width.... Or do you want the edge vertices for a path? An elipse has a bBox. That would not differentiate it from a rectangle. The object type is critical.

Thanks for the reply Rob,

i want the coordinate information to get the positional data of layers such as vias, metals. Basically i want to create a 2-D maze by extracting this information. i can convert the coordinates in different form(list of pts or bBox. or xy) in the next step . Now i want all the layers(merges) and and its coordinates(with its respective object type is fine) 

OK, if you are willing to do this destructively with flattening and merging an easier solution is available. First; flatten, merge, and convert all shapes to polygons. N.B. "rect" will remain as rect despite the convert to polygon. Load the following...

procedure(rdmShapeCoords(cv)
let((shapeCoordList )
foreach(shape cv~>shapes
case(shape~>objType
("rect" shapeCoordList=cons(list(shape~>objType shape~>lpp shape~>bBox) shapeCoordList))
("polygon" shapeCoordList=cons(list(shape~>objType shape~>lpp shape~>points) shapeCoordList))
)
)
shapeCoordList
)
)

All as    rdmShapeCoords(geGetEditCellView())

This will return a list of rect and polygon obects with layer and bBox/points info. If you want you can convert the bBox into the equivalent points list.

Thanks rob, I will try it out!!

If the objects you are dealing with are octilinear (i.e. only multiples of 90 and 45 degrees) then you could use the abe* functions. These can retrieve a representation of a layer throughout the hierarchy and avoid the flattening. For example:

abeInit(cv)
m1=abeLayerFromCellView("Metal1")
iter=abeIslandIterator(m1)
while(polygon=iter->next
  println(polygon)
)
abeDone()

The polygon variable will be the list of points for the outline of each "island".
