Delete shapes

andyL

I try to cut layers using the Points (p1,p2) of a ruler.
So far I've go the result but I'm not able to delete the original shapes on the current layer.
The script runs through without any error but still the original shape is in.

Any idea is highly appreciated ...


myLayer = layout.layer(1, 0)
l0 = pya.Region()
l0.insert(pya.Box(p1.x, p1.y ,p2.x+1000, p2.y+1000))

l1 = layout.begin_shapes(topcell,myLayer)
l2 = pya.Region(l1)
result = l2-l0

####### Here I try to delete the original shapes
shapes = topcell.shapes(myLayer)
shapes.erase
#topcell.shapes(lay).erase
########


# insert modified shapes
topcell.shapes(myLayer).insert(result)

Thanks in advance,
Andy

Hi Andy,

the solution is to clear the layer entirely:

layout.clear_layer(myLayer)

Thanks a lot Matthias,
It works as planned.


With the programmable interface KLayout is a real outstanding tool !

Cheers,
