    A SheetMetal Unfold object is derived from a Part Feature object and inherits all its properties. It has no additional properties, but its label has a default value:



    • DataLabel (String): Default value: Unfold (+ a sequential number for second and following items).
      The user editable name of this object, it may be any arbitrary UTF8 string.


    • The sheet metal should have a constant thickness.
    • Flat faces should not contain split lines.
    • Flat faces must be truly planar and not B-spline approximations.
    • Faces of bend angles must be truly cylindrical and also not B-spline approximations.
    • The Unfold feature is not parametric. If the model is modified you have to unfold it again.
