I would like to clarify the question, and Folke's answer.
Folke is entirely correct for the answer, but I want to distinguish the difference in Solid Edge between a sketch and a profile. A sketch is a feature of its own, a profile is embedded in another (solid) feature. If you created the profile geometry while constructing the protrusion, for example, that "sketch" will not be visible in draft. You MUST create a sketch feature that is independent of any modeling feature. Only those sketches can be viewed in draft.
