[Closed] Simple attach multiple objects

Hi all,

I’m stuck on something that seems so basic…

I basically want to select some objects and then attach them together. I have looked around for examples and have come up with this.

I have 3 editable polys, cy, cy1, cy2. I am trying to attach them all to cy. (hopefully mat ids will stay the same)

My code is below, what am I missing?

select $cy1
select $cy2

for i in collection do
(

polyop.attach $cy i
	
)
