Full layout BBox

laurent_c

Hello,

I have a script that I used for long to draw a box all surrounding the full layout of the active cell.
But something is now wrong and I cannot figure out why cv.layout.is_valid_layer?(li) never pass.
Please, can you help to find the missing instruction to insert the boundary_box ?

Thanks, BRgds,
Laurent
