How to use dbShapeQuery to get rect bbox from bottom to top in mosaic type?

Charley Chen

Hi All,

dbShapeQuery can get shape box from bottom to top for instance well,but I have shape inside mosaic .

How to handle shape inside mosaic from bottom to top?

Thak you,

Charley

  • Charley,

    I use a combination of dbGetHierPathTransform and abGetHierPathShape (unfortunately this function doesn't exist as a built-in):

    (defun abGetHierPathShape (overlap)
      (if (listp overlap)
        (abGetHierPathShape (cadr overlap))
        overlap))

    Then you can do (say):

    theShapes=dbShapeQuery(geGetEditCellView() list("Metal3" "drawing") enterBox()) ; use enterBox to define the rectangle for testing
    newShapes=foreach(mapcar obj theShapes dbCopyFig(abGetHierPathShape(obj) geGetEditCellView() dbGetHierPathTransform(obj)))
    newShapes~>layerName="Via1" ; just to make them stand out

    Regards,

    Andrew

    Hi Andrew ,

    Thanks for reply for solution.

    If i don't have the cellview's permission and  just get the bbox of the shape info bottom to top  , How to do it ?

    Rather than using dbCopyFig, you can use dbTransformBBox. For example:

    theShapes=dbShapeQuery(geGetEditCellView() list("Metal3" "drawing") enterBox()) ; use enterBox to define the rectangle for testing
    topBBoxes=foreach(mapcar obj theShapes dbTransformBBox(abGetHierPathShape(obj)~>bBox dbGetHierPathTransform(obj)))
