Sheetmetal glitch

Discussion created by Guest on Oct 2, 2006
I am trying to model a part that we make out of fiberglass with a layer of carbon conductor on the inside. So, I have modeled the tube, unfolded it, then added the carbon layer protrusion to the flat and tried to fold it back round. When I fold the part back, the protrusion that I added becomes a cutout. I have tried the feature as a .001" deep cutout as well, but I get the same results. Any ideas?

The pics included are
Test part - fold and flat pattern suppressed
Test part2 - flat pattern suppressed
Test part3 - all features active
