Creating Extruded Surface with API

Hi folks,

is it possible to create an extruded surface out of a sketch? Much like an extrusion, but the result should be a surface without top and bottom planes, and not an extruded boss.

I tried IFeatureManager.FeatureExtrusionThin2 without any success, and failed to find any additional info in the API help.

Any help would be appreciated.

Thank you.
