Can someone tell me what is wrong with this model, and my cut list?  I know I could not get the shelf in the middle to be sheet metal.  I also need to add doors and skin with 18 gauge sheet metal.  I am going to continue with it but not sure which direction I will go in, I know I can go into the cut list and edit the properties so that is what I am going to do.  What is it I did wrong?  any ways of adding sheet metal around the part?

life is like grapes, all purple and green f***ed up looking, until you crush them, make wine, and get smashed.  then we can see the world for what it is, spinning out of control thru the universe just u will be to smashed off the wine.  lol
