And welcome to this instructable on how to make a 3d model of a pumpkin barbeque in 123d design, which you can download here- http://www.123dapp.com/design .
This is a great barbeque for Halloween, as you can roast marshmallows through the mouth, nose and eye hole. Put the top on, and the smoke will pour out of the holes making it look very scary and spooky.

Step 1: Starting off

Finally extrude the rectangle all the way through the pumpkin, then delete the remaining square and move the lid over.
