creating linked chain

[IsleofGough]

I've bought most of the XSI tutorials, but have the maya tutorial for creating the swiss army knife. I followed along in XSI and could do all the parts up to creating a linked chain. I know how to do this in Maya, but I don't want to buy this tutorial just for this one instruction. Can anyone tell me basically how the chain was created in XSI? (the XSI modeling tutorial creates essentially the same knife)

Addenum: never mind. I figured it out (duplicate/instantiate using animation)
