Boolean operation failed after baked panelling tools with grasshopper.

Hi,

I can't do boolean operation (addition) after I baked my pattern made with the panelling tools with grasshopper. I used the Morph 3D list to generate.

Though I can do boolean operation after I used the panelling tools straight from Rhino ( without using grasshopper).

Anyone else has this problem ? 

Any recommendation ?

Thanks for the help.
