Hi everyone!! Thanks for all the support in my preovious question 

So.. I am working on three different projects. I am wondering now, which material calculators should I use for each? 

These are their charecteristics: 

1- NC v2009, registered on Nov 2011

2- CS v2009, registered on Aug 2016 

3- Campus: v2009, registered on Oct 2016

Is there a link where I can see that? Can I use the same one for the three?

In case I can use any, is there one you recommend? 

Thanks a lot!!
