How to pass values to mppBBox

Hi ,
I wrote a template for creating Nwell Ring(Yeah the substrate contact
for the PMOS transistor).
Now I'm trying to change the length of the Ring that i drew, by
passing values through the CIW..
The Code is as follows:

;Getting the id of the ROD object
;in this case Nwell Ring
obj2=getRODobj()
Output at CIW: rodObj:0xeee5f54
obj2~>mppBBox;This is the point that i want to change automatically By
passing values through the CIW
Output at CIW: ((3.66 33.86)
(12.5 34.78)
)

newPoint=list(list(4 34) list(12 40))
Output at CIW: ((4 34)
(12 40)
)
obj2~>mppBBox=newPoint
Output at CIW: *Error* setSGq: invalid ROD data - rodObj:0xeee5f54
What is the problem with the above code..?
(When i try to change the points manually by querrying the Nwell
Ring,It accepts the points i give)

Thanks and regards,
Lokesh rajendran

Lokesh,

You can't stretch a multipart path (or even a path for that matter) by changing
the bBox.

Easiest way is to do:

obj2~>dbId~>points=newPointList

where newPointList is the list of new points you want the MPP to have.

Andrew.

MPP are path-type objects.
Shouldn't they be stretched by changing the points on the path only?

If you want to write a code to change it based on size (or boundary)
of the MPP, I believe you also only have to know the enclosure of the
widest path enclosing the MPP/reference/primary path (fiuh, that's a
mouthful). Then do some calculations to get the end point co-ordinates
to be modified.

So now you have the MPP points, enclosure width and bounding box
values... some mathematical calculations may be required.

Hi Andrew,
Thanks for the help...
My code is working fine now..........
