Hi Rolf,
I don't know what you pass into that function, but
check if this object is
a proxy
or
an other object
which has no geometry to be calculated (dictionary ?)

Eg: if it is a proxy, you won't get the boundingbox because
the object is not known to ACAD and it's method to calculate
it's geometry.

Dieter!
I have a selection set filtered on Blocks and Solids and a layerlist. I
didn' know that Layername was case-sensitive. I have 4 layers, which are
filtered from the layerlist. Among them "ASHADE". When I write Ashade the
layer won't be filtered out. And I suppose that all the Block on that layer
probably give me the problem.
