Need a Skill code to get a list of elements under a plygonal shape.

AmitBiswas

I am looking for a comand in skill to get the list of elements under a polygonal shape.

There is a command

 

dbgetTrueOverlaps(
d_cellView
l_bBox
)

 here the output of this command is a list of elements. But this command only takes the input as a list of two points.

 I want to give a list of more number of points as input to the code and the output it will return a list of elements under the polygon formed by the list of input points.

If anybody knows how to get it done please repply.

Regards,

Amit

  •  Derek is correct, using dbLayerTile will break an orthogonal polygon into rectangles which can then be fed to dbGetTrueOverlaps. The first  argument for dbLayerTile is a cellView ID so you could open a scratch cellView using dbOpenCellViewByType in "s" mode (including IC6.1.3) and create the resulting rectangles there. dbLayerTile returns the dbId's for the rectangles so you could then process them from there. I often open a scratch cellView and keep it open just for this type of issue, sharing it among multiple programs.
