You don't need WinISD to design a 3 ft^3 box...all you need is about 30 seconds and a calculator...

LxWxH/1728 for external volume

For internal, subtract 2x the thickness of the wood from each measurement-

example-

12x12x12/1728= 1 ft^3 external

Ok, say the wood is 3/4" (the norm), now we subtract 2(.75) from each measurement (1.5)

So, it's 10.5x10.5x10.5/1728= .67 ft^3 internal...
