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:
{{Properties_Title|Base}}
- Label|String: Default value: 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.
