Square Meter based on material and thickness

[donaldleigh]

Evening all

I have found and edited the attached rule (Thanks to Cadline) .  This rule will, from an assembly, enter the m2 of each sheet metal part into a custom iProperty, What I would like to do (and not sure how to) is add these up based on both material and thickness, Issue I have is the material could be any number of materials and same with the thicknesses.

Cheers

I think if you had a set list of materials and thicknesses this would be much easier... I'd be interested to see how this could be done though. Maybe some kind of 2 dimensional array sorted by several columns.
