[Solved] Tried using the ABE to obtain layer within a bBox, got all abutting layer shapes instead

jriad

Hello fellow community members,

So I have two instances with their "metal1" shapes abutting. I want to extract the "metal1" shapes from one cell but not the other. What I did was:

(abeInit cv)
(abeLayerFromCellView "metal1" ?bBox (getq instance1 bBox))
What I expected is that this will extract the "metal1" shapes from instance1 but not from instance2. What ends up happening is, because the shapes are abutting, the "metal1" shapes for both instances get extracted, even though instance2 lies completely outside the bBox of instance1.
Is this the expected behavior? Is there any way I can get around it?
Thanks,
Joe

    Joe,

    Yes, it's expected because the abutting shape is seen as a single shape across the hierarchy.

    It's easy enough to fix with a bit of extra code:

    (abeInit cv)
    (setq result (abeLayerFromCellView "metal1" ?bBox (getq instance1 bBox)))
    (setq bBox (abeNewLayer))
    (abeLayerOrPtArray (getq instance1 bBox) bBox)
    (setq result1 (abeNewLayer))
    (abeLayerInside result bBox result1)

    Then result1 contains what you want (I think...)

    Hi Andrew,

    Thanks a lot. This works as expected for the case when the two instances have non-overlapping bBoxes. It will fail (as expected) if the bBoxes overlap.

    For that case I found that a good workaround is to extract the shapes from the instance's master then transform their points via dbTransformPoint.
