nominal sizes Micro

[Thad58]

OK so I figured out the material list. Now the dimensions on the joist is in inches not feet and inches. Chief said I need to write a Macro that will convert it to that but they don't give that assistants.. Anyone know how to write that Macro

[BrownTiger]

Here is my macro..... You do not have to use it....

It uses rounder function

def rounder(l)
arr = [0,4,8,9,10,12,14,16,18,20,l]
puts arr.select{|item| item < l}.max
end
 

This function rounds a lumber to 4',8',9',10',12'..... to buy list sizes

replace with [0, l] to disable it.
