Sketches need to be supported by a plane. This plane can be one of the main planes (XY, XZ, or YZ) defined by the Origin of the Body. A sketch is either extruded into a positive solid (additive), with a tool like PartDesign Pad, or into a negative solid (subtractive), with a tool like  PartDesign Pocket. The first adds volume to the final shape of the body, while the latter cuts volume from the final shape. Any number of sketches and partial solids can be created in this way; the final shape (tip) is the result of fusing these operations together. Naturally, the Body can't consist of only subtractive operations, as the final shape should be a positive solid with a non-zero volume.
