I am a relatively new user of SKILL. My problem is with the use of dBTransformBBox function. I am able to apply this function to scale the size of objects which are uniquely represented in bounding box fashion("rect" objects). My question is if this function is applicable to polygons as well.
Specifically when I apply dBTransformBBox to a shape in the active layer there is no scaling. As far as I can tell these shapes differ only in that they are represented as "polygon" objects in terms of their geometry. dBTransformCellView scales all layers in a cell view, so it should be possible to scale polygons as well. I tried to use the dbLayerSize function to achieve scaling on the active layer but I do not understand the results returned by it.cvID~>DBUPerUU returns 1000.0.I am attaching a couple of pictures that show the layout before and after the application of dbLayerSize and also some example code of what I used to achieve this.
cv_lay = dbOpenCellViewByType("SEMIREG_STM040" "SR_FA" "layout" "" "a")
shape_list = cv_lay~>shapes
OD_shape_list = nil foreach(shape shape_list if(shape~>lpp == list("OD" "drawing") then OD_shape_list = append1(OD_shape_list shape) );if );for
dbLayerSize(cv_lay "OD" list(OD1) 0.50)
dbLayerSize(cv_lay "OD" list(OD1) -0.50) [returns nil]
leLayerSize(cv_lay list("OD" "drawing") -0.50 list("OD" "drawing")) [also returns nil]
leLayerSize(cv_lay list("OD" "drawing") -0.50 list("OD" "drawing"))
I looked at other posts referring to leLayerSize (which I see in the manual is a layout editor procedural version of the dbLayerSize function), but the problem of the sizing value is still present here. There is no hierarchy in my layout.
I also tried leSizeShape for the specific shape I extract above.

Any help will be appreciated.

Thanks for the pointers. They work with the minor correction that dbLayerSize also needs the layer name on which to output the new shapes.
newShapeList = dbLayerSize( cv_lay list(car(OD_shape_list)) .05)
newShapeList = dbLayerSize( cv_lay "OD" list(car(OD_shape_list)) .05)
What is confusing for me is what is meant by user units for the scale value? Also how are the user units different from DBU's?
