How to chop hierarchical ROD object?

Slayer

 Hi all!

Could you pls. help me with chopping of the rod objects. The question is I have Instance with RodObject.

 To find this object inside instance I use rodGetOb:

 cv = geGetEditCellView();

gRing = rodGetObj("GuardRing1/GuardRing" cv); Where GuardRing1 - istanceName, GuardRing - name of the rod object;

after that, I  catch all layer on top level and take only m1 layers:

 metStripes = setof(i cv->shapes i->lpp == list("m1" "drawing"));

find m1 path rings in rod object:

 m1SubPath = setof(i gRing->subShapes car(i->lpp) == "m1");

after that, finding common part (metal intersection)  and calculate centerline point and try to make chop, for example:

 rodAddMPPChopHole(gRing list(44.44:19.36 44.44:18.85));
 

But have in CIW following warning:  *WARNING* rodAddMPPChopHole: objId rodObj:0x14b6a18c: hierarchical ROD object not allowed - name is "GuardRing1/GuardRing"

And nothing happend :(

  • It makes no sense to chop a shape within the sub-cell, surely? What if you have two instances of the block containing the guardring - and hence GuardRing1/GuardRing and GuardRing2/GuardRing ROD objects. If you were able to call rodAddChopHole on the first of these, it would modify the second too - which presumably would not be what you want - because they are in the same cell. 

    I think you'd have to flatten the instance of the cell containing the guardring first before you can add a chop hole. Or open the lower level cell (in SKILL), and then do a rodGetObj("GuardRing" lowerCv) and chop that. 

    Regards,

    Andrew.
