Regarding "dbGetTrueOverlaps()"

Neeraj Vardhan

Hi,

I am writing a code to get all instances under a marker layer. I tried to use dbGetTrueOverlaps() but it failed with an error of "*Error* dbGetTrueOverlaps: Invalid bBox - (((-0.915 0.025) (4.695 3.135)))". I have mentioned the code below, 

 

 procedure(nvGetVia3()

cv=geGetEditCellView()

x=geGetSelSet()

y=x~>bBox

shape_new=dbGetTrueOverlaps(cv y)

)

 

Thanks & Regards

Neeraj

  • If you use dbGetTrueOverlaps(), you may get a list of lists something like below. The 1st one is the ID of the selected trace.You can always eliminate it using unless like Andrew's code in the POST.

    The first ID in each list represent the instance name in the hierarchy. The last one in each list is the actual object (may be a PATH,POlygon,Shape..etc). Each list is basically a nested list of the hierarchy.

    If you have more number hierarchy you will get more depth in the nesting. If you get the idea you can easily extract the instance ID.

    One can  basically argue that the instance is a last but one in a nested list returned by dbGetTrueOverlaps().

    You can also try  dbGetInstTransform(). It may NOT work in IC5141.

     

     

     shapeList = dbGetTrueOverlaps(cv obj1~>bBox obj1~>layer 0:5)
    \t (db:217705012
    \t     (db:217517248 db:262161624)
    \t     (db:217517248 db:262161472)
    \t     (db:217517248 db:262161312)
    \t     (db:217517248 db:261977724)
    \t     (db:217517248 db:261977644)

    \t )
