OK, so if you have a single bBox you'd do: dbTransformBBox(bBox inst~>transform) where inst was the instance id of the instance of the pcell. So I mean that inst is an instance in hierarchy X-1, and the shapes within it are in the coordinate system of hierarchy X (using your terminology). To do it for your entire list, you'd do: B=foreach(mapcar bBox A dbTransformBBox(bBox inst~>transform) that would give you a list of transformed bBoxes. Hope that helps, Regards, Andrew![]()
