Example: Types of Bend
Angled Bend—The bend is formed on one side of the bend line or equally on both sides.
Rolled Bend—The bend is defined by both the radius and the amount of flat material to bend.
When you create a rolled bend, keep in mind that the bend will fail if the material, rolled into a spiral, bends through itself.
Planar Bend—The bend is formed around an axis that is perpendicular to the driving surface and sketching plane.
