Other standard shapes
Keep in mind the following when using a standard flange wall shape:
• You cannot change the material thickness direction for an Open, Flushed, Joggle, Duck, C, or Z flange.
• The bend radius value and material thickness direction are only applied to a shape that is not tangent to the attachment wall.
• You can apply rip relief only to a flange with a flush shape.
• Stretch relief is not available for a duck-shaped flange.
