Hi Chalke,

You can unfold the following types of walls, but you must right-click a planar face and not a cylinder or a cone:

  • Planar walls
  • Cylindrical walls, including large diameter cylinders (roll bends)
  • Most conical walls, such as a part with variable radius round between arcs that was shelled and converted to a sheet metal part. Parts that are made with blends between radii also unfold reliably.
  • Z bends and S bends, even when they neighbor a cylindrical or conical wall.
  • Walls that includes holes that touch a bend or are included in an object that includes a bend.
  • Double-walled parts that include a complex unbending edge.

You also might want to try including the 'Beta options', which can be found in Workbench window >> Tools >> Appearance >> Beta Options

More information on the unfold option can be found in the following references which also include some examples too.

Hope this helps,
