Removing an invalid object from a block instance

Hi,

Is there a way to remove invalid objects from a referenced block instance, in order to explode the object (block), via grasshopper? In this case, I am exploding the block using elefont

I am limiting any manipulation of the block in rhinospace (exploding, block edit, etc)

Thanks

Hej R -

Could you post an example with invalid objects?
In Rhino 8, you can use native Grasshopper components to explode blocks.
