Solidworks & SigmaNest

Hi

Does anyone out there use SolidNest in conjuction with SolidWorks.If so is it any good what are the Pro's / Con's etc.
I saw a demo a while back and it looked very limited in what itcould do, has it since been improved?
However links between a nested item and a SolidWorks part issomething we are looking at.


Thanks
