Mortal kombat help

[kenshen]

Hello if this is the wrong thread i'm sorry and please move. But I am trying to build an arcade cab in wood shop class at my school i got plans for the mortal kombat arcade cab from jakobud.com if i spelled that right. Well when i showed the plans to my woods teacher he started to tell me about how wood has thickness because when we went over the plans together He noticed there was no thickness illustrated and each page of the plans had a different scale can somebody please show me how get the plans of mortal kombat that has those two points mentioned. I also need modify the area where the screen should go to be 26 inches wide be cause the screen i am using is 25 and 1/2 inches wide. Is there any thing else i need to edit to make this work?

Download sketchup! Import the photo and trace your lines over and then resize the lines to what you need. It's free. As far as thickness, are you sure he didn't just want to know how thick a material to use? I would go for 3/4" mdf/mdo/plywood.
