Merging shapes non-interactively

I need to use the merge function in a layout via a SKILL program. Doing this interactively is easy- select everything and select "merge" from the menus. How is this done without opening a window? I don't see the merge function in the db or dd functions reference. I can open it with dbOpenCellViewByType, then what?

Thanks,

Tom Spargo

Hi Tom,
I've also found that sometimes it's better to use dbLayerOr() (with a single list of layers) to merge the shapes, and then discard the originals - in some trials I did a while ago, this had better performance than leMergeShapes with a large number of shapes.
I used this approach in solution 11328674
Best Regards,
Andrew.
