Only parts with exact
analytic cylindrical faces can be unfolded. As a test, try to insert an
axis on the cylindrical face. If you can insert an axis, the model is
an exact cylinder. If you cannot insert an axis, then the model is not
an exact cylinder and cannot be unfolded. However, sheet metal parts created
with the Lofted
Bends feature avoid this limitation and unfold appropriately.
