3D graphic illustration of my sketch

I have sketched my design of a machine and I want it to be graphically illustrated using autocad or other apps you can use.
The sketch shows my patented idea, which is a multipurpose stove. During frying, you can just pull the sliding pan to be on top of the stove. During grilling, you can pull the grill which is under the pan. The walls of the stove can also be pulled, while the other wall can be pulled up and folded, to enclose the whole stove, converting it into an oven.
